¶2 Gabriel Ponce-Rodriguez, a native and citizen of Mexico, petitions for review of the Board of Immigration Appeals’ (“BIA”) order dismissing his appeal from an immigration judge’s removal order. We have jurisdiction under 8 U.S.C. § 1252. We review de novo questions of law and constitutional claims. Avila-Sanchez v. Mukasey, 509 F.3d 1037, 1040 (9th Cir.2007). We deny the petition for review.
¶3 Because Ponee-Rodriguez’s June 18, 1996, deportation order was lawful when he was deported and the record reveals that his waiver of appeal of that order was “considered and intelligent,” the BIA did not err in concluding that he failed to demonstrate a “gross miscarriage of justice at the prior proceeding” and he therefore may not, at this point, collaterally attack his 1996 deportation order. Ramirez-Juarez v. INS, 638 F.2d 174, 175-76 (9th Cir.1980) (per curiam); see also Alvarenga-Villalobos v. Ashcroft, 271 F.3d 1169, 1172-73 (9th Cir.2001); Biwot v. Gonzales, 403 F.3d 1094, 1098 (9th Cir.2005) (waiver of right to appeal must be “considered and intelligent”).
¶4 We reject Ponce-Rodriguez’s constitutional challenge to 8 C.F.R. § 1003.44(k)(2). See Avila-Sanchez, 509 F.3d at 1040-41.
¶5 PETITION FOR REVIEW DENIED.
