SUMMARY ORDER
Keng Ying Lin, a native and citizen of the People’s Republic of China, seeks review of a May 29, 2008 order of the BIA, affirming the October 30, 2006 decision of Immigration Judge (“IJ”) Barbara A. Nelson, which denied her application for asylum, withholding of removal, and relief under the Convention Against Torture (“CAT”). In re Keng Ying Lin, No. [ AXX XXX XXX ] (B.I.A. May 29, 2008), affg No. [ AXX XXX XXX ] (Immig. Ct. N.Y. City Oct. 30, 2006). We assume the parties’ familiarity with the underlying facts and procedural history in this case.
As an initial matter, we note that Lin explicitly abandons any challenge to the IJ’s determination that she was ineligible for asylum. Moreover, we lack jurisdiction to consider Lin’s argument that the IJ erred in denying her application for CAT relief where she did not challenge before the BIA the IJ’s denial of that category of relief. See 8 U.S.C. § 1252(d)(1); see also Karaj v. Gonzales, 462 F.3d 113, 119 (2d Cir.2006). We dismiss the petition for review to that extent.
In addition to the statutory requirement that petitioners exhaust the categories of relief they seek, 8 U.S.C. § 1252(d)(1), petitioners must also raise to the BIA the specific issues they later raise in this Court. See Foster v. INS, 376 F.3d 75, 78 (2d Cir.2004). While not jurisdictional, this judicially imposed exhaustion requirement is mandatory. Lin Zhong v. U.S. Dep’t of Justice, 480 F.3d 104, 119-20 (2d Cir.2007). Here, the government correctly argues that Lin failed to exhaust before the BIA her argument that the IJ erred by denying her application for withholding of removal on credibility grounds. Accordingly, we decline to consider this issue. See Lin Zhong, 480 F.3d at 124. Because the adverse credibility determination was dispositive of Lin’s request for withholding of removal, her failure to exhaust is fatal to her petition for review. See Steevenez v. Gonzales, 476 F.3d 114, 118 (2d Cir.2007).
For the foregoing reasons, the petition for review is DENIED in part and DISMISSED in part. As we have completed our review, the pending request for oral argument in this petition is DENIED.
. In any event, we note that the IJ did not err in denying Lins application for withholding of removal on credibility grounds where she admitted that in her previous removal proceedings, she had lied to the IJ about her claim of forcible abortion. See Siewe v. Gonzales, 480 F.3d 160, 170 (2d Cir.2007) (holding that "a finding of fraudulent evidence redounds upon all evidence the probative force of which relies in any part on the credibility of the petitioner ... [a]nd where an IJs finding of fabrication (supported by substantial evidence) serves as the basis for discrediting other evidence, a reviewing court is in no position to conclude that the discrediting of the remaining evidence is unsupported by substantial evidence”).
