Rafael Antonio Urquilla-Avalos unconditionally pleaded guilty to unlawful presence in the United States after deportation following a felony conviction for a drug trafficking offense. He was sentenced to 37 months of imprisonment and three years of supervised release. He appeals his conviction and sentence.

The Government correctly argues that Urquilla-Avalos’ unconditional guilty plea waived all non-jurisdictional defects in the trial court proceedings against Urquilla-Avalos and bars an as-applied constitutional challenge to 8 U.S.C. § 1326(b). United States v. Spruill, 292 F.3d 207, 215 (5th Cir. 2002); United States v. Johnson, 194 F.3d 657, 659 (5th Cir. 1999), vacated on other grounds and remanded, 530 U.S. 1201, 120 S.Ct. 2193, 147 L.Ed.2d 230 (2000), prior opinion reinstated with modification, 246 F.3d 749 (5th Cir. 2001). However, Urquilla-Avalos’ unconditional *448 guilty plea did not waive his right to assert that 8 U.S.C. § 1326(b) was facially unconstitutional. See United States v. Knowles, 29 F.3d 947, 952 (5th Cir. 1994) (citing Menna v. New York, 423 U.S. 61, 62, 96 S.Ct. 241, 46 L.Ed.2d 195 (1975) (state court conviction)).

For the first time on appeal, Urquilla-Avalos contends that the “felony” and “aggravated felony” provisions of 8 U.S.C. § 1326(b) are unconstitutional. As Urquilla-Avalos concedes, this argument is foreclosed by Almendarez-Torres v. United States, 523 U.S. 224, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998), which this court must follow “unless and until the Supreme Court itself determines to overrule it.” United States v. Izaguirre-Flores, 405 F.3d 270, 277-78 (5th Cir. 2005) (internal quotation marks and citation omitted), petition for cert. filed (July 22, 2005) (No. 05-5469).

The conviction and sentence are AFFIRMED.
