MEMORANDUM **

Alfredo Mercado Moreno, a native and citizen of Mexico, petitions pro se for review of the Board of Immigration Appeals’ order dismissing his appeal from an immigration judge’s decision denying his application for cancellation of removal. We have jurisdiction under 8 U.S.C. § 1252. We deny the petition for review.

In his opening brief, Mercado Moreno fails to address, and therefore has waived any challenge to, the agency’s dispositive determination that he failed to provide credible testimony supporting the continuous physical presence required for cancellation of removal. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir. 1996) (issues not specifically raised and argued in a party’s opening brief are waived).

In light of this disposition, we do not reach Mercado Moreno’s hardship contentions.

PETITION FOR REVIEW DENIED.
