ON REMAND FROM THE SUPREME COURT OF THE UNITED STATES•

We affirmed the conviction and sentence of Sergio Duran-Gomez (“Duran”). United States v. Duran-Gomez, 115 Fed.Appx. 743 (5th Cir. 2004) (per curiam). The Supreme Court vacated and remanded for further consideration in light of United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). We requested and received supplemental letter briefs addressing the impact of Booker.

Duran argued in his initial brief and in his petition for a writ of certiorari that his sentence should be vacated because he was sentenced under the erroneous assumption that the Guidelines were mandatory. Our review of this issue is for plain error. United States v. Valenzuela-Quevedo, 407 F.3d 728, 732 (5th Cir. 2005), cert. denied — U.S. —, 126 S.Ct. 267, 163 L.Ed.2d 240 (2005). Although Duran has satisfied the first two criteria for establishing plain error, he is required to demonstrate that “the sentencing judge — sentencing under an advisory scheme rather than a mandatory one — would have reached a significantly different result.” United States v. Mares, 402 F.3d 511, 521 (5th Cir. 2005), cert. denied — U.S. —, 126 S.Ct. 43, 163 L.Ed.2d 76 (2005); Valenzuela-Quevedo, 407 F.3d at 733. Duran has not met his burden because there is “no evidence in the record suggesting that the district court would have imposed a lesser sentence under an advisory guidelines system.” United States v. Taylor, 409 F.3d 675, 677 (5th Cir. 2005).

In his initial brief, Duran challenged the constitutionality of 8 U.S.C. § 1326(b) and the validity of Almendarez-Torres v. United States, 523 U.S. 224, 118 S.Ct. 1219, 140 L.Ed.2d 350 (1998). Duran conceded that his argument was foreclosed by existing precedent, but he sought to preserve the issue for further review. Nothing in the Supreme Court’s Booker decision affected the validity of Almendarez-Torres. See *667 Booker, 125 S.Ct. at 756 (the Booker holding applies to any fact (other than a prior conviction)). The decision in Apprendi v. New Jersey, 530 U.S. 466, 120 S.Ct. 2348, 147 L.Ed.2d 435 (2000), left Almendarez-Torres intact. See Apprendi, 530 U.S. at 489-90, 120 S.Ct. 2348 (“fact of a prior conviction” need not be submitted to a jury).

Because nothing in the Supreme Court’s Booker decision requires us to change our prior affirmance in this case, we therefore reinstate our judgment affirming Duran’s conviction. For the reasons set forth in this opinion on remand, his sentence is also AFFIRMED.

AFFIRMED.
