TORRUELLA, Circuit Judge. This is the sixth (and hopefully the final) installment of Petitioner David Eduardo Castañeda’s tumultuous voyage through our nation’s immigration system. Castañeda began his journey more than twenty years ago, when he arrived in the United States seeking political asylum based on the alleged persecution he suffered at the hands of the Shining Path, a ruthless guerrilla organization bent on overthrowing the government of Perú. On February 6, 2012, after his case generated three court-of-appeals opinions, one district court opinion, and numerous administrative determinations, an Immigration Judge (IJ) finally granted asylum to Castañeda and his family members. Subsequently, on April 12, 2012, we entered final judgment closing Castañeda’s case. See Castañeda-Castillo v. Holder, 676 F.3d 1 (1st Cir.2012) (“Castañeda V”). In so doing, we cautioned that we were taking “no position on the deadline for filing, or potential merit of, an application for attorneys’ fees under the Equal Access to Justice Act.” Id. at 3. On July 12, 2012, Castañeda filed such a petition, seeking to be awarded the attorneys’ fees he incurred while litigating his case in federal court, as well as the attorneys fees related to the administrative proceedings he underwent. After careful consideration, we grant his petition in part and deny it in part. I. Background The full history of this case is chronicled in the four prior opinions of this court and one opinion of the U.S. District Court for the District of Massachusetts. See Castañeda-Castillo v. Gonzales, 464 F.8d 112 (1st Cir.2006) (“Castañeda I”); Castañeda-Castillo v. Gonzales, 488 F.3d 17 (1st Cir.2007) (en banc) (“Castañeda II ”); United States v. Castañeda-Castillo, 739 F.Supp.2d 49 (D.Mass.2010) (“Castañeda III”); Castañedar-Castillo v. Holder, 638 F.3d 354 (1st Cir.2011) (“Castañeda IV”); and Castañeda V, 676 F.3d 1. The following relevant facts are culled from those decisions. A. The Accomarca Massacre Castañeda, a former lieutenant in the Peruvian army, was accused of taking part in the massacre of innocent villagers in Accomarca, Perú (the “Accomarca Massacre”) in 1985, during the country’s bloody struggle with the revolutionary Shining Path movement. Castañeda II, 488 F.3d at 19. Castañeda led one of the four patrols involved in the Accomarca operation but was three to five miles away from the massacre, id., and was not in any way involved in, or responsible for, the heinous actions of the larger force. Castañeda IV, 638 F.3d at 357; Castañeda II, 488 F.3d at 19. The Peruvian Senate Human Rights Commission investigated the events and determined that Castañeda’s squad “was not involved in any confrontations with [the] fugitive civilians” who were killed. Castañeda II, 488 F.3d at 19. Despite this finding, Castañeda was charged with homicide and abuse of authority before a military tribunal, although said charges were ultimately dismissed. Castañeda V, 676 F.3d at 2. The dismissal was affirmed by the Supreme Council of Military Justice, Perú’s highest court with jurisdiction over military justice matters. See id.; Castañeda III, 739 F.Supp.2d at 52. Notwithstanding, Castañeda’s name became associated with the Massacre, and he and his family began receiving death threats from the Shining Path, Castañeda IV, 638 F.3d at 357-58, a violent group that “is among the world’s most ruthless guerrilla organizations,” Castañeda I, 464 F.3d at 114 n. 3. Thereafter, members of the Shining Path sent death threats to Castañeda, attempted to murder him twice and to kidnap one of his daughters, and set off explosives in front of his parent’s home. Castañeda I, 464 F.3d at 120-21. In fact, a bomb that went off shortly after he left a restaurant with his family killed several innocent bystanders. Castañeda IV, 638 F.3d at 358. In 1991, following the murder of his neighbor, a former military officer who apparently was also in the Shining Path’s cross-hairs, Castañeda and his family decided to flee Perú, and they arrived in the United States on tourist visas. Castañeda I, 464 F.3d at 120-21. B. The Petition for Asylum; Castañeda I and II In 1993, Castañeda filed the petition for asylum that gave rise to the instant saga. Castañeda V, 676 F.3d at 2. It was not until 2004 that the petition was denied by an IJ, who found that Castañeda was barred from applying for asylum and withholding of removal because he had participated in the persecution of others on account of their political opinion, given his presumed role in the military during the Accomarca Massacre. Id. The Board of Immigration Appeals (BIA) affirmed in 2005. Id. Castañeda was subsequently incarcerated and spent the next five years in the Department of Homeland Security’s (DHS) custody, until he was finally released on bail in August 2010. Id. In the meantime, Castañeda pursued a petition for review before us challenging the BIA’s denial of his petition for asylum (the “first petition for review”). Said petition gave rise to our decision in Castañeda I, where we found that the BIA’s determination that Castañeda had engaged in the persecution of others was not supported by substantial evidence. Castañeda I, 464 F.3d at 137. Subsequently, we granted the government’s request to rehear the case en banc, which resulted in our decision in Castañeda II. There, we held that for the persecutor bar to apply to Castañeda, he must have had prior or contemporaneous knowledge that his actions during the Accomarca Massacre had the effect of assisting in the persecution of others. Castañeda II, 488 F.3d at 21-22. We remanded the case back to the immigration agencies for them to determine whether Castañeda was credible when he denied having said knowledge. Id. at 24-26. Following remand, the IJ again denied Castañeda’s application for asylum and withholding of removal, holding that (1) he had not met his burden of proving that he did not persecute others; (2) he had not established that he was persecuted on account of his membership in a particular social group or because of his political opinion; and (3) he had not established that he had an objectively reasonable fear of future persecution. Castañeda TV, 638 F.3d at 359. In May 2009, the BIA reversed the IJ as to point (1), concluding that there was insufficient evidence to support the IJ’s finding that Castañeda had prior or contemporaneous knowledge of the Accomarca Massacre. Id. Nevertheless, the BIA upheld the IJ’s decision as to points (2) and (3), reasoning that the Shining Path did not target Castañeda because he was a member of a particular social group — members of the military who were linked to the Accomarca Massacre — rather, they targeted him out of revenge for the massacre. Id. at 362-63. The BIA then found that Castañeda failed to prove that he had a genuine fear of future persecution were he to return to Perú and thus denied his application for asylum. Id. at 359. C. Castañeda IV In June 2009, Castañeda filed a petition for review of the BIA’s ruling before this court (the “second petition for review”). Said petition gave rise to our decision in Castañeda IV, where we held that the BIA committed legal error when it reasoned that the Shining Path’s vindictive motivation precluded a finding of persecution on account of a statutorily protected ground. Id. at 363. In light of the “ordinary remand rule,” we sent the case back to the BIA for consideration of whether “Peruvian military officers whose names became associated with the Accomarca massacre” constituted a cognizable social group. Id. We emphasized, however, that the “unusually prolonged and convoluted history of this case prompted] us to take the further step of retaining jurisdiction over Castañeda’s appeal while the BIA addresses these issues on remand.” Id. On October 11, 2011, the BIA ruled that military officers linked to the Accomarca Massacre comprised a cognizable social group and that Castañeda suffered past persecution due to his membership in such a group. Castañeda V, 676 F.3d at 3. The case was remanded to the IJ so that she could determine whether the government could rebut the presumption that Castañeda harbored a well-founded fear of persecution if he were to return to Perú. Id. On February 6, 2012, an IJ granted asylum to Castañeda and his family, effectively laying to rest an application for asylum that had been pending for almost twenty years. Id. D. Castañeda V Castañeda’s legal battles, however, were not over. He returned to this court and filed a motion requesting that we enter a final judgment in his favor, noting that, in Castañeda IV, this court had elected to retain jurisdiction over the post-remand proceedings, and that it was now time to “officially terminate this [ejourt’s jurisdiction.” In response, the government argued that we had no authority to issue a final judgment, because we “lack[ed] jurisdiction to pass judgment on the merits of this case.” Id. It maintained that Congress granted courts of appeals jurisdiction to review only final orders of removal, and that, as the IJ’s decision to grant asylum to Castañeda was not such an order, we lacked jurisdiction to enter a final judgment effectively sanctioning her award of asylum as final. In Castañeda V, we rejected that argument. 676 F.3d at 1. We explained that when we remanded this case to the BIA in Castañeda IV, we “explicitly retained jurisdiction for the express purpose of ensuring a speedy resolution of this case.” Id. at 3. As such, we dismissed as moot the petition for review over which we had retained jurisdiction in Castañeda IV, and directed the clerk of the court to issue a final judgment in Castañeda’s favor. Id. The clerk of the court entered said judgment on April 12, 2012, the same date that Castañeda V was decided. E. The Extradition Proceedings During the pendency of Castañeda’s second petition for review, on March 9, 2010, the government filed a request for the extradition of Castañeda to his native Perú. Castañeda III, 739 F.Supp.2d at 50. The request stemmed from the government of Perú’s renewed decision to charge Castañeda with the crimes of aggravated murder, kidnapping and forced disappearance arising from the events surrounding the Aecomarca Massacre. This request was the result of a change in Perú’s government and the revocation of an amnesty law passed in 1995 which protected members of the military from further prosecution. Id. at 52. No effort was made to extradite Castañeda until five years after the new Peruvian government filed charges against him. Id. at 53. Nevertheless, the government argued before the federal district court in Massachusetts that Castañeda should be held in custody without bail until a determination of extraditability was made under 18 U.S.C. § 1834. Id. at 50. On August 17, 2010, the district court in Castañeda III granted Castañeda’s request to be released on bail, finding that he had established special circumstances warranting such relief. Id. at 63-64. The government ultimately decided to voluntarily dismiss the extradition proceedings against Castañeda in April 2011. F. The Habeas Corpus Proceedings Castañeda also filed a petition for a writ of habeas corpus with the district court on February 2010, noting that he had been detained by DHS for nearly four and a half years while he waited for his asylum application to be adjudicated, despite having no criminal history and not being subject to mandatory detention. Given the extradition request, Castañeda was transferred to the custody of the U.S. Marshal service, and the government moved for the dismissal of the habeas petition on the grounds that Castañeda had named the wrong custodian, presumably the DHS. However, as previously recounted, Castañeda ended up being released on bail on August 2010, in the context of his extradition proceeding. II. The Petition for Attorney s’ Fees Having dotted the tortured factual landscape, we now proceed to discuss Castaneda’s petition for attorneys’ fees. On July 12, 2012, Castañeda filed the. amended petition for attorneys’ fees that is now before us. He first seeks an award for fees he incurred in relation to his first petition for review of the BIA’s September 9, 2005 removal order, which resulted in this court’s decisions in Castañeda I and Castañeda II (en banc). Second, Castaneda seeks an award of attorneys’ fees incurred in relation to his second petition for review of the BIA’s May 26, 2009 removal order, which resulted in this court’s decisions in Castañeda TV and Castañeda V. In addition to seeking an award with respect to those four decisions, Castañeda seeks an award of attorney’s fees and expenses incurred during the post-remand administrative removal proceedings that took place after the remands ordered in Castañeda II and Castañeda TV. Castañeda also seeks an award of attorneys’ fees and expenses incurred during the extradition and habeas proceedings that were conducted before the district court, as well as during several administrative bond proceedings that were conducted before the Executive Office for Immigration Review (“EOIR”). Finally, Castañeda also seeks to be awarded the fees incurred during the preparation of both his original and amended application for attorneys’ fees. III. The Equal Access to Justice Act In the United States, each party is usually required to bear its own attorneys’ fees; “the prevailing party is not entitled to collect them from the loser.” Buckhannon Bd. & Care Home, Inc. v. W. Va. Dep’t of Health & Human Res., 532 U.S. 598, 602, 121 S.Ct. 1835, 149 L.Ed.2d 855 (2001). The Equal Access to Justice Act (“EAJA”), 28 U.S.C. § 2412, is an exception to that rule. It provides in part that a court shall award to a prevailing party ... fees and other expenses ... incurred by that party in any civil action ... including proceedings for judicial review of agency action, brought by or against the United States in any court having jurisdiction of that action, unless the court finds that the position of the United States was substantially justified or that special circumstances make an award unjust. 28 U.S.C. § 2412(d)(1)(A). The EAJA aims to “ensure that certain individuals ... will not be deterred from seeking review of, or defending against, unjustified governmental action because of the expense involved.” Aronov v. Napolitano, 562 F.3d 84, 88 (1st Cir.2009) (citing Scarborough v. Principi, 541 U.S. 401, 407, 124 S.Ct. 1856, 158 L.Ed.2d 674 (2004)). The Act “reduces the disparity in resources between individuals ... and the federal government.” Id. (citing H.R. Rep. No. 99-120(1), at 4 and 1985 U.S.C.C.A.N. at 133). Nevertheless, since it effectively amounts to a partial waiver of sovereign immunity by the United States, its scope must be strictly construed in favor of the government. Ardestani v. I.N.S., 502 U.S. 129, 137, 112 S.Ct. 515, 116 L.Ed.2d 496 (1991). The EAJA also mandates that a party seeking an award of attorneys’ fees must submit his petition “within thirty days of final judgment in the action.” 28 U.S.C. § 2412(d)(1)(B). Consequently, in order for Castañeda to prove himself eligible for an award of attorneys’ fees under the EAJA, he must establish (1) that he is the prevailing party in the civil action; (2) that his petition was timely filed; (3) that the government’s position was not substantially justified; and (4) that no special circumstances make an award against the government unjust. Comm’r, I.N.S. v. Jean, 496 U.S. 154, 158, 110 S.Ct. 2316, 110 L.Ed.2d 134 (1990); Norris v. S.E.C., 695 F.3d 1261, 1264 (Fed.Cir.2012). IV. Eligibility Under EAJA We now proceed to discuss whether Castañeda meets the four requirements listed above. We do so in turn. A. Prevailing Party Status 1. Applicable Law The term “prevailing party,” as used in the EAJA and other fee-shifting statutes, is a “legal term of art.” Buckhannon, 532 U.S. at 603, 121 S.Ct. 1835. To be considered a prevailing party, a party must be “awarded some relief by the court.” Id. The party must also show (1) a “material alteration of the legal relationship of the parties” and (2) a “judicial imprimatur on the change.” Aronov, 562 F.3d at 89. The Supreme Court has held that there are only two situations that meet the judicial imprimatur requirement: (1) where the party has “received a judgment on the merits” or (2) where the party “obtained a court-ordered consent decree.” Buckhannon, 532 U.S. at 605, 121 S.Ct. 1835. A party’s mere success in accomplishing its objectives, however, is insufficient to confer it prevailing party status. Id. at 606, 121 S.Ct. 1835; Aronov, 562 F.3d at 89. 2. Discussion The government recognizes that Castañeda is the prevailing party in Castañeda II and Castañeda IV, but not in Castañeda V. It argues that our decision to issue a final judgment in Castañeda V did not confer upon Castañeda the status of prevailing party, because said decision did not effectively “rule on the merits” of Castañeda’s second petition for review. The government stresses that this court had already ruled on the merits of such a petition in Castañeda IV, and that, following the remand ordered in that case, the immigration agencies had independent authority to grant Castañeda asylum. Once the decision was made by an IJ to grant Castañeda asylum, the argument goes, such decision did not depend on this court’s judicial imprimatur or approval in the form of a final judgment. Therefore, the government argues that the parties’ legal relationship remained the same both before and after we entered final judgment in Castañeda V, and that such judgment cannot confer prevailing party status upon Castañeda under the EAJA. Castañeda, for his part, argues that he is the prevailing party in each of the proceedings of Castañeda I, Castañeda II, Castañeda IV and Castañeda V. He claims that the government has mistakenly considered Castañeda IV and Castañeda V to be two separate cases, when in reality they are not, because this court did not issue a mandate after the Castañeda IV decision; instead, it decided to retain jurisdiction and refrain from terminating that proceeding. As such, Castañeda argues the decisions in Castañeda IV and Castañeda V should be construed as forming part of the same “civil action” under the EAJA, an action which was not terminated until after Castañeda V. Therefore, Castañeda maintains he became a prevailing party in Castañeda V, when this court noted its previous findings in Castañeda IV, entered a final judgment and issued a mandate effectively terminating the case. We agree with Castañeda that he should be accorded prevailing party status with respect to Castañeda V. In reaching our conclusion, we have found instructive the Federal Circuit’s ruling in Former Employees of Motorola Ceramic Products v. United States, 336 F.3d 1360 (Fed.Cir.2003). There, a pair of employees who had been dismissed from their respective employments petitioned the Department of Labor (DOL) for benefits. Id. at 1362. The DOL denied their petitions and the employees sought review before the Court of International Trade (CIT). Id. The CIT found the DOL’s decision to be erroneous and thus remanded the ease back to the DOL for reconsideration, but retained jurisdiction over the proceedings during remand. Id. The employees were granted their benefits and afterwards filed an application for attorneys’ fees pursuant to the EAJA. Id. at 1363. The CIT denied the petition, holding that its remand to the DOL did not constitute a judgment on the merits that afforded prevailing party status to the employees, and the employees appealed to the Federal Circuit. Id. In order to determine whether the CIT’s remand order to the DOL constituted relief on the merits, the Federal Circuit relied on the Supreme Court’s holdings in Sullivan v. Hudson, 490 U.S. 877, 109 S.Ct. 2248, 104 L.Ed.2d 941 (1989) and Shalala v. Schaefer, 509 U.S. 292, 113 S.Ct. 2625, 125 L.Ed.2d 239 (1993), and distilled the following rule: where the plaintiff secures a remand requiring further agency proceedings because of alleged error by the agency, the plaintiff qualifies as a prevailing party (1) without regard to the outcome of the agency proceedings where there has been no retention of jurisdiction by the court, or (2) when successful in the remand proceedings where there has been a retention of jurisdiction. Former Emps., 336 F.3d at 1366. It follows that, under the second prong of the rule, a court’s remand order to an administrative agency, with retention of jurisdiction, creates a prevailing party “if the party obtains the benefits it sought before the agency.” Id. at 1367 (our emphasis); see also Flom v. Holly Corp., 276 Fed. Appx. 615, 617 (9th Cir.2008) (citing Former Employees with approval). The court thus found that the employees qualified as prevailing parties under this prong, because they obtained relief at the DOL after the CIT had remanded the case due to the agency’s error. Former Emps., 336 F.3d at 1367. In the case at bar, our remand order in Castaneda TV explicitly stated that we were to retain jurisdiction during the agency proceedings, due to the “unusually prolonged and convoluted history of this case.” Castañeda TV, 638 F.3d at 363. There is no doubt that a material alteration of the relationship between the parties occurred when an IJ granted Castañeda his request for asylum. However, in order to become a prevailing party, there must have been a “judicial imprimatur” of that change. That imprimatur did not come until our decision in Castañeda V, when we acknowledged that “all factual and legal issues relating to Petitioners’ eligibility for asylum [had] now been resolved in their favor by the administrative agency” and directed the clerk of the court to issue a final judgment. Castañeda V, 676 F.3d at 2. In essence, the final judgment we entered pursuant to Castañeda V is the final judgment “on the merits” we would have entered after deciding Castañeda TV, were it not for our decision to retain jurisdiction over the ensuing agency proceedings. In requesting that this court enter such a final judgment, Castañeda correctly attempted to comply with the strictures of the Buckhannon decision, which required him to secure a judgment on the merits or a court-approved settlement in order to be considered a prevailing party. 532 U.S. at 605-06, 121 S.Ct. 1835. He achieved the desired result and thus became a prevailing party once the final judgment was entered. As can be seen, in arriving at this conclusion we have traveled down a similar path to the one followed in Former Employees, except that we consider that Castañeda only became a prevailing party when, per his request, we entered a final judgment pursuant to Castañeda V. We think this was a necessary step, given Buckhannon’s requirement that there be a “judgment on the merits,” id., and the Supreme Court’s holding in Melkonyan v. Sullivan, 501 U.S. 89, 94, 111 S.Ct. 2157, 115 L.Ed.2d 78 (1991), that a “final judgment” under the EAJA “can only be the judgment of a court of law.” B. Timeliness 1. Background The government’s second argument is that Castañeda’s petition for attorneys’ fees is untimely under 28 U.S.C. § 2412(d)(1)(B). Said provision states that a proper application for attorneys’ fees must be submitted “within thirty days of final judgment in the action.” Id. A “final judgment” is defined by the EAJA as a judgment that is final and unappealable. Id. at § 2412(d)(2)(G). Castañeda notes that this court elected to retain jurisdiction after its decision to remand in Castañeda TV, which was decided on March 24, 2011. Following remand, Castañeda was able to prevail and obtain asylum in the immigration agencies, and he thus returned to this court requesting that we enter a final judgment in his favor. We entered such a final judgment, according to our own terms, on April 12, 2012, pursuant to our order in Castañeda V. Therefore, Castañeda argues that said judgment became a “final judgment,” within the meaning of the EAJA, on July 11, 2012, when the period for seeking certiorari to the Supreme Court expired. See Sup. Ct. R. 13.1. The decision to remand in Castañeda TV, according to him, also became final and unappealable as of that date, because this court retained jurisdiction over his petition for review pending the completion of the post-remand administrative proceedings at the immigration agencies. Consequently, as he filed his amended petition for attorneys’ fees the day after, on July 12, 2012, Castañeda claims he is well within the 30-day time period allowed by the EAJA. The government, for its part, claims that Castañeda’s petition is untimely. It counters that if Castañeda wanted to recover attorneys’ fees for the proceedings that led to the decision in Castañeda TV, he should have filed his petition by July 22, 2011, that is, 120 days after this court issued its judgment in that decision. The government claims that the judgment issued pursuant to Castañeda IV became a “final judgment” under the EAJA on June 22, 2011, despite this court’s decision to retain jurisdiction on the matter and forgo entering its own final judgment until Castañeda V was decided. In support of its contention, it cites to several Supreme Court cases which have interpreted when a judgment becomes “final” for EAJA purposes, but those cases deal with judicial review of Social Security Administration (“SSA”) cases under 42 U.S.C. § 405(g) by the district courts. The government, nevertheless, relies on those cases to argue that this court was stripped of its ability to retain jurisdiction over Castañeda’s petition for review following our remand order in Castañeda IV, and that instead we were supposed to enter a final judgment relinquishing jurisdiction on the matter, thereby triggering the 120-day time period to file a petition for attorneys’ fees under the EAJA. 2. Supreme Court Jurisprudence on Judicial Review of SSA Cases In order to understand the government’s argument, it is necessary to provide a brief summary of the specialized nature of judicial review of SSA agency determinations. In SSA cases, a district court reviewing a decision rendered by an SSA agency may only remand a case back to that agency under either sentence four or sentence six of section 405(g). See Melkonyan, 501 U.S. at 90, 111 S.Ct. 2157. Under sentence four of section 405(g), the district court must enter “a judgment, affirming, modifying, or reversing the decision of the Commissioner of Social Security, with or without remanding the cause for a rehearing,” 42 U.S.C. § 405(g), whereas under sentence six, the district court “does not rule in any way as to the correctness of the administrative determination,” but instead remands the case to the agency for further fact finding, Melkonyan, 501 U.S. at 98, 111 S.Ct. 2157. Further, following a sentence six remand, the agency “must return to the district court to ‘file with the court any such additional or modified findings of fact and decision,’ ” along with a supplemental record of the post-remand proceedings. Id. (quoting 42 U.S.C. § 405(g)). The Supreme Court distinguished between sentence four and sentence six remand orders for the first time in Sullivan v. Finkelstein, 496 U.S. 617, 110 S.Ct. 2658, 110 L.Ed.2d 563 (1990). In Finkelstein, a case that did not concern the EAJA, the SSA agency had denied a widow’s application for disability benefits, and the widow sought review in the district court under section 405(g). The district court reversed in part the decision of the SSA agency and remanded the case so that the agency could determine whether the widow could engage in any gainful activity. The Secretary of Health and Human Services appealed to the court of appeals, but said court dismissed the appeal for lack of jurisdiction, reasoning that the district court’s decision to remand the case to the SSA agency was not an appealable “final decision” under 28 U.S.C. § 1291. On certiorari, the Supreme Court differed and held that the district court’s remand was a sentence four remand under section 405(g), and that said type of remand order is an appealable final decision. The Court reasoned that the district court’s order was “unquestionably” a judgment because “it terminated the civil action challenging the Secretary’s final determination that [the] respondent was not entitled to benefits, set aside that determination, and finally decided that the Secretary could not follow his own regulations in considering the disability issue.” Id. at 625, 110 S.Ct. 2658. The Court ruled that sentence four of section 405(g) “directs the entry of a final, appealable judgment even though that judgment may be accompanied by a remand order.” Id. at 629, 110 S.Ct. 2658 (our emphasis). It placed much emphasis on the fact that sentence eight of section 405(g) provides that “[t]he judgment of the court shall be final except that it shall be subject to review in the same manner as a judgment in other civil actions.” Id. at 625, 110 S.Ct. 2658 (emphasis in original). A year after Finkelstein was decided came the Supreme Court’s decision in Melkonyan, where the Court was faced with the question of whether an administrative decision rendered following a remand from a district court could be a “final judgment” within the meaning of the EAJA. The Court answered in the negative, holding that the “plain language [of the EAJA] makes clear that a ‘final judgment’ under § 2412 can only be the judgment of a court of law.” Melkonyan, 501 U.S. at 94, 111 S.Ct. 2157 (quoting 28 U.S.C. § 2412(d)(1)(B)). According to the Court, “[i]n sentence four [remand] cases, the [EAJA] filing period begins after the final judgment (‘affirming, modifying, or reversing’) is entered by the [district] court and the appeal period has run, so that the judgment is no longer appealable.” Id. at 102, 111 S.Ct. 2157 (quoting 42 U.S.C. § 405(g) and citing 28 U.S.C. § 2412(d)(2)(G)). On the other hand, the Court clarified that the EAJA filing period in sentence six remand cases “does not begin until after the post-remand proceedings are completed, the Secretary returns to court, the court enters a final judgment, and the appeal period runs.” Id. The Court then concluded that “in § 405(g) actions, remand orders must either accompany a final judgment affirming, modifying or reversing the administrative decision in accordance with sentence four, or conform with the requirements outlined by Congress in sentence six.” Id. at 101-02, 111 S.Ct. 2157 (emphasis added). Two years later, in Schaefer, the Supreme Court reviewed an EAJA application for attorneys’ fees filed after the district court remanded an SSA case pursuant to sentence four of section 405(g). Schaefer is significant because the district court in that case clarified that, although it was remanding the case under sentence four, it retained jurisdiction and planned to enter a final sentence four judgment after the completion of the post-remand administrative proceedings. 509 U.S. at 295, 113 S.Ct. 2625. The EAJA applicant in that case thus argued that the “final judgment,” for purposes of the EAJA, would be the final judgment entered by the district court after all post-remand proceedings were completed at the agency, and not the district court’s order remanding the case back to the agency. Id. at 297, 113 S.Ct. 2625. The Supreme Court rejected this argument, stating that it “was inconsistent with the plain language of sentence four, which authorizes a district court to enter a judgment ‘with or without’ a remand order, not a remand order ‘with or without’ a judgment.” Id. (quoting Finkelstein, 496 U.S. at 629, 110 S.Ct. 2658). It further noted that a sentence four remand order constitutes a final judgment under the EAJA, as it “terminat[es] the litigation with victory for the plaintiff.” Id. at 301, 113 S.Ct. 2625. Thus, the Court held that the 30-day time period for filing an EAJA petition for attorneys’ fees, following a sentence four remand, begins immediately upon expiration of the time to appeal said remand order. Id. at 297-98, 113 S.Ct. 2625. 3. The Government’s Arguments The government contends that Schaefer, as well as the other Supreme Court cases mentioned above, compels the conclusion that remands in the immigration context should be treated the same way as remands in the social security context. Particularly, the government posits that our remands to the BIA in Castañeda II and Castañeda IV are akin to the remands authorized under sentence four of section 405(g). It emphatically calls our attention to case law from the Third, Seventh and Ninth Circuits, holding that remands to the BIA in immigration cases are analogous to the sentence four remands at issue in the Supreme Court’s SSA cases. See Johnson v. Gonzales, 416 F.3d 205, 209-10 (3d Cir.2005); Muhur v. Ashcroft, 382 F.3d 653, 654-55 (7th Cir.2004); Rueda-Menicucci v. I.N.S., 132 F.3d 493, 495 (9th Cir.1997). Therefore, the government contends that, if Castañeda wanted to recoup the attorneys’ fees and expenses he incurred in Castañeda II and Castañeda IV, he should have filed his petition for attorneys’ fees within 30 days after the judgments issued in those cases became final and unappealable, that is, by September 20, 2007, and July 22, 2011, respectively. Instead, Castañeda filed his petition on July 12, 2012 (91 days after we issued our decision in Castañeda V) which is long after the judgments entered in Castañeda II and Castañeda IV “became final,” according to the government’s calculations. The decision to retain jurisdiction following our remand in Castañeda IV, the government posits, is inconsistent with the Supreme Court’s definition of a “final judgment” under the EAJA. According to the government’s reading of the Supreme Court’s jurisprudence, this court had to enter a final judgment after deciding Castañeda IV, because our decision there effectively ruled “on the merits” of Castañedas petition for review, vacated the decision of the administrative agency, and remanded the case for further proceedings consistent with the opinion. The government argues that, after this course of action, there was nothing left for this court to do but to relinquish jurisdiction and enter a judgment on the merits, as commanded by sentence four of section 405(g) and Schaefer. The government goes on to argue that, despite this court’s decision to retain jurisdiction over the post-remand proceedings in Castañeda IV, it would have been able to appeal the judgment in that case as a “final order” under 28 U.S.C. § 1291. According to the government, the final judgment we entered in Castañeda V cannot make the Castañeda IV judgment appeal-able again, as the former did not purport to reaffirm the latter’s ruling on the merits. Therefore, we are urged to construe the judgment entered pursuant to Castañeda IV as a “final judgment” for purposes of the EAJA, once the time period for seeking certiorari before the Supreme Court expired. 4. Castañeda’s Arguments Castañeda, for his part, argues that this court’s remand in Castañeda TV should be construed as a sentence six remand, as opposed to a sentence four remand. He strenuously notes that this court elected to retain jurisdiction over the post-remand administrative proceedings following our decision in Castañeda IV, which according to him, effectively takes that remand outside of the purview of sentence four of section 405(g). Although he admits that sentence four requires a remanding court to relinquish jurisdiction over the matter and terminate the case on the merits, he points out that there is no similar provision in any of the statutes governing judicial review of immigration cases. The Third, Seventh and Ninth Circuit cases relied upon by the government, he also claims, are distinguishable from his case, because in those cases each court plainly relinquished jurisdiction over the case when it remanded to the BIA. In addition, following a sentence six remand, the SSA agency is required to return to the district court and file any additional or modified findings of fact, as well as its decision adjudicating the merits of the petitioner’s claims, so that the court may review it and enter a final judgment on it. Castañeda theorizes that we attempted to do something similar in our Castañeda IV remand order, because although we did not require the BIA to make any additional findings of fact, we did direct the parties to file joint status reports on the progress of the administrative proceedings every sixty days. Castañeda claims that he expected to continue filing said reports until a final decision was reached at the immigration agencies, at which time he would file said decision with this court so that we could enter a final judgment on it, as required by sentence eight of section 405(g). Therefore, Castañeda urges us to treat the remand ordered in Castañeda TV as a sentence six remand, and the judgment entered pursuant to Castañeda Fas a “final judgment” for EAJA purposes, once the period for seeking certiorari to the Supreme Court expired. 5. Analysis We have not had the opportunity to consider the issue of what constitutes a final judgment for EAJA purposes when a court of appeals remands an immigration case for further administrative proceedings while retaining jurisdiction over those proceedings. The government here invites us to equate judicial remand orders in the immigration context with remand orders in the social security context. Particularly, the government urges us to apply the sentence four — sentence six remand dichotomy to remands undertaken in the immigration context. We, however, find it difficult to accept the government’s invitation in this regard. First of all, in Tyler v. Fitzsimmons, we noted that “[w]hen acting outside the strictures of the Social Security statute, a reviewing court normally is not confined to two types of remand, but [rather] possesses the ‘inherent’ authority to condition its remand order as it deems appropriate.” 990 F.2d 28, 32 n. 3 (1st Cir.1993) (citing Melkonyan, 501 U.S. at 101, 111 S.Ct. 2157). This is because judicial remand orders in the social security context are governed by the detailed and inflexible language that Congress adopted in section 405(g). In contrast, judicial review of final orders of removal in the immigration context are governed by a different statute: section 242 of the Immigration and Nationality Act (INA), as amended by the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), 8 U.S.C. § 1252. In particular, section 242(a)(1) of the INA states that: Judicial review of a final order of removal (other than an order of removal without a hearing pursuant to [the expedited-removal provisions for undocumented aliens arriving at the border found in] section 1225(b)(1) of this title) is governed only by chapter 158 of Title 28 [known as the Hobbs Act], except as provided in subsection (b) of this section and except that the court may not order the taking of additional evidence under section 2347(c) of such title. 8 U.S.C. § 1252(a)(1). The Hobbs Act, which is incorporated by the provision above, sets out the jurisdiction of the courts of appeals in reviewing agency orders. See 28 U.S.C. § 2349(a). Needless to say, both the INA and the Hobbs Act employ starkly different language when it comes to regulating judicial remands to the immigration agencies, as compared to that used in section 405(g) to regulate remands to the SSA agencies. Despite this incongruity, the government urges us to adopt the sentence four — sentence six remand dichotomy featured in section 405(g), when no such dichotomy exists in either the INA or the Hobbs Act. In so doing, the government has not pointed us to any language in the INA nor in the Hobbs Act which would support its proposition that this court lacked authority to retain jurisdiction over the post-remand administrative proceedings that followed our decision in Castañeda IV, and that we lacked authority to enter a final judgment in Castañeda V, thereby terminating the proceedings which had originated with Castañeda IV. In any event, the parties’ assertion that we could, in theory, remand an immigration case using a sentence-six-style remand is troublesome. As already discussed, under sentence six of section 405(g), a district court “may at any time order additional evidence to be taken before the Commissioner of Social Security.” 42 U.S.C. § 405(g). However, remanding a case to an immigration agency with the purpose of having it collect additional evidence, at least at the behest of a petitioner, appears to be prohibited under a plain reading of section 242 of the INA, which states that “the court may not order the taking of additional evidence under section 2347(c) of [Title 28].” 8 U.S.C. § 1252(a)(1); see also I.N.S. v. St. Cyr, 533 U.S. 289, 312 n. 36, 121 S.Ct. 2271, 150 L.Ed.2d 347 (2001). It follows that courts of appeals lack the authority to approve a party’s request to remand a case back to the BIA so that said party may present additional evidence. See Najjar v. Ashcroft, 257 F.3d 1262, 1281 (11th Cir.2001). This is not to say that the government’s argument is entirely without merit. We must recognize that the Third, Seventh and Ninth circuits have expressed a willingness to equate remands to the BIA in the immigration context with the sentence four remands featured in the social security context. But as Castañeda correctly points out, the remands at issue in those cases were ordered with a concomitant relinquishment of jurisdiction by the court. See, e.g., Johnson, 416 F.3d at 209-10 (“[The court of appeals] entered judgment in [petitioner’s] favor and relinquished jurisdiction.”) (emphasis added). Consequently, those circuits had no trouble likening those remands to the sentence four remands existing in the social security context. The fact remains that we have no way of knowing how those circuits would have ruled had the courts in those cases decided to retain jurisdiction over the post-remand proceedings. Conversely, in our decision in Castañeda TV, we cited to cases from the Second and Seventh Circuits to support our authority to retain jurisdiction over the post-remand proceedings. See Ucelo-Gómez v. Gonzales, 464 F.3d 163, 172 (2d Cir.2006) (directing the BIA to issue an opinion responsive to the limited remand within forty-nine days, and retaining jurisdiction in the interim), Asani v. I.N.S., 154 F.3d 719, 725 (7th Cir.1998)(retaining jurisdiction during a limited remand to the BIA to determine whether, inter aha, changed circumstances in the petitioner’s home country supported a finding of a well-founded fear of future persecution); and Yang v. McElroy, 277 F.3d 158, 164 (2d Cir.2002). Therefore, there is countervailing authority, at least from the Second and Seventh Circuits, that effectively undermines the government’s position that we lacked the authority to retain jurisdiction in Castañeda IV. What’s more, the law of the case doctrine governs on this issue. In Castañeda V, we explicitly rejected the government’s argument that we were without authority to enter a final judgment terminating the proceedings. Chi. & N.W. Transp. Co. v. United States, 574 F.2d 926, 929 (7th Cir.1978) (“Appellate reconsideration of issues that have already been decided in an earlier appeal is ordinarily foreclosed by the doctrine of law of the case.”). In addition, by retaining jurisdiction over the post-remand proceedings in Castaneda IV, we instilled in Castañeda a legitimate expectation that, were he to prevail at the immigration agencies and obtain asylum, he could return to this court and seek the entry of a final judgment to effectively terminate the proceedings surrounding his petition for review. There is no reason to suppose that Castañeda did not reasonably believe that this potential final judgment would anchor the filing period for his EAJA attorneys’ fees petition. Adopting the government’s argument to the contrary would effectively force us to backtrack from our decision to retain jurisdiction in Castañeda IV and to nullify the final judgment we entered pursuant to Castañeda V. We reject this argument, primarily because it has no basis in either the INA or the Hobbs Act, and because adopting it would eviscerate the legitimate expectation we ourselves created in the mind of Castañeda. Moreover, we are also mindful that the legislative intent behind the EAJA counsels against creating confusion with regards to what constitutes a “final judgment” for purposes of the statute. See H.R. Rep. 99-120, n. 26 (provision of the EAJA defining “final judgment,” 28 U.S.C. § 2412(d)(2)(G), “should not be used as a trap for the unwary resulting in the unwarranted denial of fees.”). Based on the foregoing, we reject both the government’s argument that we should treat the remand order in Castañeda IV as a sentence four remand, and Castañeda’s argument that we should treat said remand as a sentence six remand. We agree with Castañeda, though, that the remand order in Castañeda IV is entirely distinguishable from the remands at issue in the cases decided by the Second, Seventh and Ninth Circuits. Accordingly, we hold that said remand should not be construed as a sentence four remand, and that the final judgment entered pursuant to Castañeda V should be treated as a “final judgment” under the EAJA, once the period for seeking certiorari before the Supreme Court expired. Since that occurred on July 11, 2012, and Castañeda filed his petition for attorneys’ fees the day after, we deem that said petition is timely as to the proceedings that led to our decisions in Castañeda IV and Castañeda V. 6. Castañeda I and II Castañeda also seeks an award for the attorneys’ fees he incurred during the proceedings that led to our earlier decisions in Castañeda I and II, arguing those fees may be included alongside the ones expended in Castañeda IV and H As recounted earlier, the government claims that if Castañeda wanted to recover the attorneys’ fees he incurred in Castañeda I and II, he should have filed an EAJA petition on or before September 20, 2007, that is, 30 days after the judgment in Castañeda II became final and unappealable. In essence, the government believes that Castañeda was required to file two EAJA petitions for attorneys’ fees, one for the proceedings that culminated in Castañeda II, and another for the proceedings that ended in Castañeda V. It claims that both sets of proceedings should be construed as separate “civil action[s]” under the EAJA, because they adjudicated different petitions for review and because this court did not retain jurisdiction over the post-remand administrative proceedings that followed Castañeda II. For the reasons that follow, we agree with the government. Castañeda argues that requiring him to have filed two different petitions for attorneys’ fees would be “wasteful, needlessly time consuming for the judicial system” and would “belie[ ] the underlying purpose of the EAJA, and def[y] a common sense approach to litigating EAJA claims.” His argument here mainly rests on two eases: (1) the Supreme Court’s decision in Jean, 496 U.S. 154, 110 S.Ct. 2316, and (2) the Second Circuit’s decision in Gómez-Beleno v. Holder, 644 F.3d 139 (2d Cir.2011). Specifically, Castañeda relies on language from Jean, where the Court stated that “the EAJA — like other fee-shifting statutes — favors treating a case as an inclusive whole, rather than as atomized line-items.” 496 U.S. at 161-62, 110 S.Ct. 2316. He argues that treating a case “as an inclusive whole” means treating both of his petitions for review as a single civil action under the EAJA, which in turn warrants finding his EAJA petition timely with respect to the fees incurred in Castañeda I and II. We think Castañeda reads Jean too broadly. Said case did not involve a petitioner who was seeking a fee award for multiple petitions for review; rather, the issue at stake in Jean was whether a prevailing party could be barred from recovering the attorneys’ fees it incurred during the fee litigation stage of the proceedings, if the government is able to prove that its position during that specific stage was substantially justified. 496 U.S. at 156, 110 S.Ct. 2316. The Court answered that question in the negative, holding that the EAJA’s “substantial justification” requirement is a “single finding that ... operates as a one-time threshold for fee eligibility.” Id. at 160, 110 S.Ct. 2316. Therefore, the decision in Jean, which went more to the EAJA’s “substantial justification” requirement, rather than its statute of limitations, does not help Castañeda in this regard. Castañeda also relies on Gómez-Beleno, where the Second Circuit treated two separate petitions for review as a single civil action for purposes of attorneys’ fees under the EAJA. The court allowed the prevailing party in that case to recover the fees expended in both proceedings, even though the EAJA filing period for the first petition for review had already passed. The court in Gómez-Beleno, however, made it clear that the government did not argue that the two petitions for review in that case should have been treated as separate civil actions, and thus the argument was deemed to have been forfeited. 644 F.3d at 145 n. 3. Nevertheless, Castañeda points out that the court could have, motu proprio, excluded the fees incurred by the petitioner during the first petition for review, based purely on the language contained in the EAJA’s statute of limitations provision. The court declined to travel down that path and instead relied on Jean’s “inclusive whole” language as an additional basis for upholding the award of fees in relation to the first petition for review. Id. As such, Castañeda invites us to follow the Second Circuit’s lead and allow him to recover the fees incurred in both Castañeda I and II. We do not accept this invitation. As previously discussed, we do not agree that Jean should be read as broadly as Castañeda and the Second Circuit seem to suggest. In addition, the Second Circuit may have ruled otherwise had the government decided to take up the issue. Instead, we find ourselves favoring the approach taken by the Third, Seventh and Ninth Circuits in Johnson, Muhur and Rueda-Menicucci, respectively, where those courts held that a judgment remanding a case to the BIA for further proceedings constitutes a final judgment for purposes of the EAJA’s statute of limitations. The remands featured in those cases are exactly like the remand we ordered in Castañeda II; they were all issued after the circuit court reversed the BIA’s erroneous denial of an asylum application and they were entered without the concomitant retention of jurisdiction that characterized our remand order in Castañeda IV. As such, we conclude that the judgment we entered pursuant to Castañeda II should be construed as a final judgment for EAJA purposes, once the period for seeking certiorari before the Supreme Court had expired. Since Castañeda did not file an EAJA petition to recoup the fees expended in those proceedings, his current application must be denied as to those fees. Our conclusion in this regard is further reinforced by the statutory language of the EAJA, its legislative history and common sense. The EAJA states that “[a] party seeking an award of fees and other expenses shall, within thirty days of final judgment in the action, submit an application for fees.... ” 28 U.S.C. § 2412(d)(1)(B) (emphasis added). The Supreme Court has noted that the word “shall” ordinarily connotes an intention by Congress “to impose discretionless obligations.” López v. Davis, 531 U.S. 230, 241, 121 S.Ct. 714, 148 L.Ed.2d 635 (2001); Lexecon Inc. v. Milberg Weiss Bershad Hynes & Lerach, 523 U.S. 26, 35, 118 S.Ct. 956, 140 L.Ed.2d 62 (1998) (“[T]he mandatory ‘shall’ ... normally creates an obligation impervious to judicial discretion.”); Anderson v. Yungkau, 329 U.S. 482, 485, 67 S.Ct. 428, 91 L.Ed. 436 (1947) (the term “shall” is “ordinarily [t]he language of command” (internal quotation marks omitted)). But see Gutiérrez de Martínez v. Lamagno, 515 U.S. 417, 432-33 n. 9, 115 S.Ct. 2227, 132 L.Ed.2d 375 (1995) (“Though ‘shall’ generally means ‘must,’ legal writers sometimes use, or misuse, ‘shall’ to mean ‘should,’ ‘will,’ or even ‘may.’ ”). Given that the EAJA is a partial waiver of the government’s sovereign immunity, and so must be strictly construed in favor of the government, Ardestani, 502 U.S. at 137, 112 S.Ct. 515, and that we have described the EAJA’s filing period as jurisdictional, Tyler, 990 F.2d at 30, we find that the word “shall” in this context means “must.” See also Aronov, 562 F.3d at 88 (“Whatever flexibility there may be in interpreting fee shifting statutes involving awards against parties other than the United States, such flexibility does not exist as to EAJA applications.” (citing Lehman v. Nakshian, 453 U.S. 156, 161, 101 S.Ct. 2698, 69 L.Ed.2d 548 (1981))). Therefore, it follows that if Castañeda wanted to recover the fees he incurred during the proceedings leading up to Castañeda II, he “must” have filed an EAJA petition as to those proceedings on or before September 20, 2007, which is 30 days after the judgment in that civil action became final for EAJA purposes. Since Castañeda failed to do so, this court is without jurisdiction to entertain his present fee petition as to those proceedings. Our holding is also driven by a desire to avoid confusion for parties and legal counsel engaged in litigating petitions for review such as the ones at issue here. Suppose that Castañeda had actually prevailed in the immigration agencies following our remand in Castañeda II. Most likely, his award of asylum would have been entered after the EAJA filing period for the Castañeda II judgment had passed. Castañeda would have thus found himself in a position where he could not recover the fees expended during the judicial proceedings leading up to Castañeda II, nor the fees expended during the subsequent post-remand administrative proceedings. He could not have tethered his EAJA petition to the IJ’s order granting him asylum, because said order would not qualify as a “final judgment” under the EAJA. See Melkonyan, 501 U.S. at 94, 111 S.Ct. 2157 (stating that “a ‘final judgment’ under [the EAJA] can only be the judgment of a court of law.”). Nor could he have relied on 5 U.S.C. § 504, a provision of the EAJA that allows prevailing parties to recover the fees incurred during administrative proceedings, because said provision does not apply to proceedings governed by the INA. See Ardestani, 502 U.S. at 137, 112 S.Ct. 515 (concluding that administrative immigration proceedings do not fall under 5 U.S.C. § 504). One can easily see how adopting Castañeda’s argument in this regard may leave similarly situated litigants at a dead end with respect to attorneys’ fees if they fail to file a fee petition following a Castañeda //-type judgment and subsequently become prevailing parties at the agency level. Our holding here is meant to provide a clear time frame for filing a petition for attorneys’ fees under the EAJA in the immigration context, and to avoid any confusion among the parties as to that time frame. In summary, we find that we are without jurisdiction to award Castañeda the attorneys’ fees he seeks with respect to Castañeda I and II. His petition is thus denied as to those fees. C. Other Proceedings Before delving into the issue of whether the government’s position was substantially justified, we must pause to address Castañeda’s arguments that he is entitled to an award for the fees he incurred during the administrative proceedings that followed Castañeda II and Castañeda IV, as well as the ones incurred during his habeas corpus and extradition proceedings. We begin by analyzing whether he is eligible to recover the fees he incurred in the post-remand administrative proceedings that followed Castañeda IV. 1. The post-Castañeda IV agency proceedings Castañeda seeks an award for the attorneys’ fees he incurred during the post-remand administrative proceedings that took place after Castañeda IV. As previously discussed, a party may not rely on 5 U.S.C. § 504 to recoup fees expended during an immigration agency proceeding. However, in Hudson, the Supreme Court held that certain administrative proceedings may be considered to form part of a “civil action” for which fees may be awarded under the EAJA. 490 U.S. at 892, 109 S.Ct. 2248. Castañeda thus relies on Hudson to argue that the post-remand administrative proceedings that followed our decision in Castañeda TV qualify as part of the civil action for which he is attempting to recover fees. We agree with him and proceed to explain our reasoning. In Hudson, a SSA case decided before Finkelstein, Melkonyan and Schaefer, the district court carried out a sentence four remand to the SSA agency, while retaining jurisdiction over the ensuing administrative proceedings. The petitioner was able to prevail on remand and subsequently filed an EAJA application for attorneys’ fees with the district court, where, inter alia, he sought to recover the fees he incurred during the post-remand administrative proceedings. The Hudson court held that petitioner could recover such fees, and it established the following rule: [wjhere a court orders a remand to the [agency] in a benefits litigation and retains continuing jurisdiction over the case pending a decision from the Secretary which will determine the claimant’s entitlement to benefits, the proceedings on remand are an integral part of the “civil action” for judicial review, and thus attorney’s fees for representation on remand are available subject to the other limitations in the EAJA. 490 U.S. at 892,109 S.Ct. 2248. The Court explained that certain qualifying administrative proceedings are “so intimately connected with judicial proceedings as to be considered part of the ‘civil action’ for purposes of a fee award.” Id. Those qualifying classes of administrative proceedings were defined by the Court to be those “where ‘a suit has been brought in a court,’ and where ‘a formal complaint within the jurisdiction of a court of law1 remains pending and depends for its resolution upon the outcome of the administrative proceedings.” Id. Evidently, the holding in Hudson turned out to be at odds with later Supreme Court cases regarding sentence four remands, as Hudson sanctioned a district court’s use of a sentence four remand while retaining jurisdiction over the post-remand agency proceedings. Recall that in Finkelstein, the Court held that a district court may not effectuate a sentence four remand while simultaneously retaining jurisdiction over the post-remand proceedings. 496 U.S. at 624-25, 110 S.Ct. 2658. The Justices recognized this incongruity in Schaefer and thus decided to narrow the scope of Hudson, writing that they no longer “considered] the holding of Hudson binding as to sentence-four remands that are ordered (as they should be) without retention of jurisdiction, or that are ordered with retention of jurisdiction that is challenged.” Schaefer, 509 U.S. at 300, 113 S.Ct. 2625. The government argues that Hudson is now binding only as to sentence six remands where a court “does not rule in any way as to the correctness of the administrative determination,” and remands the case to the agency for further fact-finding. Since Castañeda IV was not a sentence six remand, the argument goes, Castañeda may not rely on Hudson to recover the fees incurred in the post-remand administrative proceedings that followed that decision. This narrow reading of Hudson is mistaken. Although the Court in Schaefer, in a footnote, stated that “Hudson remains good law as applied to remands ordered pursuant to sentence-six,” and that it was “limiting Hudson to sentence-six cases,” we believe this language mea
