   SUMMARY ORDER

Yue Xian Li and Cun Xi Zheng, natives and citizens of the People’s Republic of China, seek review of an April 24, 2009, order of the BIA affirming the June 21, 2007, decision of Immigration Judge (“IJ”) Margaret R. Reiehenberg, which denied their application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). In re Yue Xian Li, Cun Xi Zheng, Nos. [ AXXX XXX XXX ]/[ AXXX XXX XXX ] (B.I.A. Apr. 24, 2009), aff'g Nos. [ AXXX XXX XXX ]/[ AXXX XXX XXX ] (Im-mig. Ct. N.Y. City June 21, 2007). We assume the parties’ familiarity with the underlying facts and procedural history in this case.

Under the circumstances of this case, we review the IJ’s decision as modified by the BIA’s decision. See Xue Hong Yang v. U.S. Dep’t of Justice, 426 F.3d 520, 522 (2d Cir.2005). The applicable standards of review are well-established. See 8 U.S.C. § 1252(b)(4)(B); see also Manzur v. U.S. Dep’t of Homeland Sec., 494 F.3d 281, 289 (2d Cir.2007).

1. Asylum and Withholding of Removal

Substantial evidence supports the agency’s adverse credibility determination. Petitioners admit that they fabricated their claim that Li underwent a forced abortion and that they submitted fraudulent documents in support of that claim. They argue, however, that because they voluntarily recanted their false claim, it cannot be the basis for an adverse credibility finding. They explain that because they were uneducated and did not speak English, they were left with no other choice but to assert the claim given to them by the snakehead and immigrant service agency that were assisting them. We are not unsympathetic to this argument, having recognized that immigrants are a “vulnerable population ... who often arrive unfamiliar with our language and culture, in economic deprivation and in fear.” Aris v. Mukasey, 517 F.3d 595, 600 (2d Cir.2008). Yet, although applicants should be encouraged to recant false testimony and disavow fraudulent evidence, it does not follow that the agency must credit testimony and evidence the applicant later presents. Here, the IJ did not err in applying the maxim falsus in uno, falsus in omnibus, and disbelieving Petitioners’ new claim involving a forced IUD insertion. See Siewe v. Gonzales, 480 F.3d 160, 170 (2d Cir.2007) (finding that once an IJ concludes that a document is false, he or she is, subject to certain limitations, “free to deem suspect other documents (and to disbelieve other testimony) that depend for probative weight upon [the applicant’s] veracity”).

Accordingly, the credibility determination was supported by substantial evidence. The IJ’s adverse credibility determination is fatal to Petitioners’ challenge to the denial of their application for asylum and withholding of removal. See Paul v. Gonzales, 444 F.3d 148, 154-55 (2d Cir.2006).

II. CAT Relief

Petitioners also assert that they are eligible for CAT relief based on their illegal departure from China and that the agency erred in failing to consider that claim. Petitioners are correct that neither the IJ nor the BIA specifically addressed their . claim that they would be jailed and tortured for illegally departing China. Yet even assuming this was error, see Ramsameachire v. Ashcroft, 357 F.3d 169, 184-85 (2d Cir.2004)(“[T]he BIA’s decision with . respect to an alien’s claims for asylum and - withholding of removal ... should never ... be determinative of the alien’s CAT claim.”), we decline to remand because doing so would be futile, see Xiao Ji Chen v. U.S. Dep’t of Justice, 471 F.3d 315, 339 (2d Cir.2006). As we have held time and again, the BIA does not err in finding applicants ineligible for CAT relief when they claim only that they would be imprisoned in China for their illegal departure and that torture occurs in Chinese prisons. See Mu Xiang Lin v. U.S. Dep’t of Justice, 432 F.3d 156, 159-60 (2d Cir.2005); see also Mu-Xing Wang v. Ashcroft, 320 F.3d 130, 143-44 (2d Cir.2003) (requiring an alien to demonstrate that someone in his “particular alleged circumstances” would more likely than not be tortured). Because Petitioners make precisely this claim, and allege no particular circumstances indicating a likelihood that they will be tortured, we can “ ‘confidently predict’ that the agency would reach the same decision” were we to remand. Xiao Ji Chen, 471 F.3d at 339.

For the foregoing reasons, the petition for review is DENIED. As we have completed our review, the temporary stay of removal that the Court previously granted in this petition is VACATED, and the pending motion for a stay of removal in this petition is DISMISSED as moot.

      . Although both the BIA and the IJ rejected Petitioners' claim of a fear of future persecution based on the birth of their three children, Petitioners do not challenge that determina- . tion here. Accordingly, we deem any such ,. challenge waived. See Yueqing Zhang v. Gonzales, 426 F.3d 540, 541 n. 1, 545 n. 7 (2d Cir.2005).
