United States v. Maturin, 499 F.3d 1243 (11th Cir. Sept. 11, 2007) (federal conviction and sentence based on guilty plea to illegally reentering the U.S. after having previously been deported is affirmed over claim that defendant is not subject to a 17-month sentence enhancement as the term of imprisonment for his offense ended more than 15 years before his reentry, as that aggravated felony requirement applies only to foreign convictions).
