   MEMORANDUM

Ricardo Pacheco-Martinez, a native and citizen of Mexico, petitions pro se for review of the decision of the Board of Immigration Appeals denying, as untimely filed, his motion to reopen the underlying denial of his application for cancellation of removal based on his failure to establish the requisite hardship to a qualifying relative.

Petitioner has waived any challenge to the BIA’s order denying his motion to reopen by failing to raise any arguments related to the BIA’s dispositive determination that the motion to reopen was untimely. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259-60 (9th Cir.1996). This court lacks jurisdiction to review petitioner’s contention that the BIA should have reopened proceedings sua sponte. See Ekimian v. INS, 303 F.3d 1153, 1159 (9th Cir.2002).

PETITION FOR REVIEW DISMISSED. 
      
       This disposition is not appropriate for publication and is not precedent except as provided by 9th Cir. R. 36-3.
