In this consolidated appeal, Jose Gerardo Ramos-Garcia appeals only from his guilty-plea conviction for knowingly making a false statement on a resident alien application (No. 05-50095); Ramos-Garcia abandons any challenge with respect to the revocation of his supervised release relating to his prior illegal reentry conviction (No. 05-50037).

Ramos-Garcia contends that his sentence is invalid in light of United States v. Booker, — U.S. -, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), because the sentencing judge applied the sentencing guidelines as if they were mandatory. We review for plain error. United States v. Valenzuela-Quevedo, 407 F.3d 728, 732 (5th Cir. 2005), petition for cert. filed (July 25, 2005) (No. 05-5556). To prevail under a plain error analysis, Ramos-Garcia must show, among other things, that the error prejudiced him by adversely affecting his substantial rights. Id. at 733.

Ramos-Garcia fails to establish that he would have received a lower sentence had the district court applied the sentencing guidelines as advisory rather than mandatory. See id. at 733-34. He thus fails to establish prejudice to his substantial rights. See id.

AFFIRMED.
