Mauro Guzman-Arroyo appeals from his guilty-plea conviction for illegal reentry of a deported alien. For the first time on appeal, he argues that his sentence should be vacated and the case remanded for resentencing in light of United States v. Booker, — U.S.-, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). He does not allege that a Sixth Amendment violation occurred but, instead, asserts that the district court would have imposed a lesser sentence under an advisory sentencing scheme. Guzman-Arroyo’s claim fails to meet the plain-error standard because he has not shown that the error affected his substantial rights. See United States v. Mares, 402 F.3d 511, 521 (5th Cir. 2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517); United States v. Valenzuela-Quevedo, 407 F.3d 728, 732-33 (5th Cir. 2005).

AFFIRMED.
