MEMORANDUM **

Guadalberto Virgilio Rojas-Santos, and Guadalupe Isabel Santos-Ambrosio, peti *739 tion pro se for review of the decision of the Board of Immigration Appeals denying them second motion to reopen the underlying denial of their application for cancellation of removal based on their failure to establish the requisite hardship to their qualifying United States citizen children.

Petitioners do not raise any arguments concerning the BIA’s denial of them second motion to reopen as being untimely and numerically barred, and therefore petitioners have waived any challenge to that decision. See Martinez-Serrano v. INS, 94 F.3d 1256, 1259 (9th Cir. 1996) (issues not specifically raised and argued in a party’s opening brief are waived).

PETITION FOR REVIEW DENIED.
