   SUMMARY ORDER

Alena Alexandrovna Humen, a citizen of Belarus, seeks review of an April 22, 2008 order of the BIA, affirming the May 11, 2006 decision of Immigration Judge (“IJ”) Steven R. Abrams, which denied her application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). In re Alena Alexandrovna Humen, No. [ AXXX XXX XXX ] (B.I.A. Apr. 22, 2008), aff'g No. [ AXXX XXX XXX ] (Immig. Ct. N.Y. City May 11, 2006). We assume the parties’ familiarity with the underlying facts and procedural history in this case.

When the BIA’s opinion fully adopts the IJ’s decision, this Court reviews the IJ’s decision. See Mei Chai Ye v. U.S. Dep’t of Justice, 489 F.3d 517, 523 (2d Cir.2007). We review the agency’s factual findings, including adverse credibility determinations, under the substantial evidence standard. See 8 U.S.C. § 1252(b)(4)(B); see also Corovic v. Mukasey, 519 F.3d 90, 95 (2d Cir.2008). We review de novo questions of law and the application of law to undisputed fact. See Salimatou Bah v. Mukasey, 529 F.3d 99, 110 (2d Cir.2008).

Before the BIA, Humen failed to exhaust any challenge to the agency’s adverse credibility finding. In addition to the statutory requirement that petitioners exhaust each category of relief, see 8 U.S.C. § 1252(d)(1), this Court generally will not consider arguments regarding individual issues that were not exhausted before the agency. See Lin Zhong v. U.S. Dep’t of Justice, 480 F.3d 104, 107 n. 1, 122-23 (2d Cir.2007). While not jurisdictional, this judicially-imposed issue exhaustion requirement is mandatory. Id. at 119-20. In particular, a petitioner must challenge all findings that are dispositive of her claims, and the failure to do so is fatal to her petition for review. See Steev-enez v. Gonzales, 476 F.3d 114, 117-18 (2d Cir.2007).

In her appeal to the BIA, Humen failed to challenge any of the findings that formed the basis of the IJ’s adverse credibility determination. Indeed, she did not even acknowledge that the IJ made such a determination. Her argument to the BIA, that “[biased on the entire record, it is clear that Judge’s decision does not support a finding that she has not met her burden of proof,” was not sufficient to exhaust the arguments she raises for the first time before this Court. See id.

Furthermore, while the BIA adopted and affirmed the IJ’s adverse credibility finding, its mere mention of that finding does not excuse Humen’s failure to offer any meaningful challenge before the BIA. Cf. Waldron v. INS, 17 F.3d 511, 515 n. 7 (2d Cir.1994); Xian Tuan Ye v. DHS, 446 F.3d 289, 296-97 (2d Cir.2006). Because we find that Humen failed to exhaust any challenge to the agency’s adverse credibility finding, and because that finding was dispositive of Humen’s remaining applications for relief, see Majidi v. Gonzales, 430 F.3d 77 (2d Cir.2005), we deny the petition for review. See Steevenez, 476 F.3d at 117-18.

For the foregoing reasons, the petition for review is DENIED. As we have completed our review, the pending motion for a stay of removal in this petition is DISMISSED as moot. 
      
      . We note that the Government has asserted exhaustion as an affirmative defense in this case. See Lin Zhong, 480 F.3d at 124. In addition, Humen has explicitly waived any challenge to the agency's denial of her application for relief under the CAT.
