MEMORANDUM **

Kalwinderjit, a native and citizen of Indonesia, petitions for review of the Board of Immigration Appeals’ order dismissing his appeal from an immigration judge’s decision (“IJ”) denying his application for asylum, withholding of removal, and protection under the Convention Against Tor *765 ture (“CAT”). We have jurisdiction pursuant to 8 U.S.C. § 1252. We review for substantial evidence, Husyev v. Mukasey, 528 F.3d 1172, 1177 (9th Cir. 2008), and we deny the petition for review.

In his opening brief, Kalwinderjit fails to challenge the agency’s dispositive determination that his asylum claim is time-barred. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir. 1996) (issues not supported by argument are deemed waived).

Substantial evidence supports the agency’s adverse credibility determination because Kalwinderjit’s vague and inconsistent testimony as to when he hid in the garbage container to elude his persecutors gave the IJ reason to question Kalwinderjit’s credibility and Kalwinderjit failed to provide corroborating evidence to support his claim of memory loss. See Sidhu v. INS, 220 F.3d 1085, 1091-92 (9th Cir. 2000). In the absence of credible testimony, Kalwinderjit’s withholding of removal claim fails. See Farah v. Ashcroft, 348 F.3d 1153, 1156 (9th Cir. 2003).

Because Kalwinderjit’s CAT claim is based on the same statements the agency found not credible, and no other evidence shows it is more likely than not he would be tortured if returned to Indonesia, substantial evidence supports the agency’s denial of CAT relief. See id. at 1156-57.

PETITION FOR REVIEW DENIED.
