MEMORANDUM **

Cenobio Evaristo Santiago-Santiago, a native and citizen of Mexico, petitions for review of the Board of Immigration Appeals’ order dismissing his appeal from an immigration judge’s decision denying his motion to reopen. We have jurisdiction under 8 U.S.C. § 1252. We deny the petition for review.

In his opening brief, Santiago-Santiago fails to address, and therefore has waived any challenge to, the agency’s dispositive determination that the motion to reopen was untimely filed. 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); 8 C.F.R. § 1003.23(b)(1).

PETITION FOR REVIEW DENIED.
