Ambrose Agwuibe appeals his 63-month sentence on a conviction for conspiracy to commit wire fraud, wire fraud, and aiding and abetting. 18 U.S.C. §§ 2, 371, 1343. For the first time on appeal, Agwuibe argues that his 12-level enhancement for fraud in excess of $200,000, his four-level enhancement for fraud involving more *742 than 50 victims, and his two-level enhancement for obstruction of justice were unconstitutional under Blakely v. Washington, 542 U.S. 296, 124 S.Ct. 2531, 159 L.Ed.2d 403 (2004).

Because Agwuibe raises these arguments for the first time on appeal, they are reviewed for plain error. See United States v. Mares, 402 F.3d 511, 520 (5th Cir. 2005), petition for cert. filed (Mar. 31, 2005) (No. 04-9517). Agwuibe fails to demonstrate that the district court would have reached a different result under an advisory guidelines scheme. See id. at 521-22. Accordingly, Agwuibe cannot establish plain error with respect to the district court’s sentencing enhancements. See id.

AFFIRMED.
