United States v. Esparza, 678 F.3d 389, (5th Cir. Apr. 20, 2012) (record evidence is sufficient to justify the trial judge's conclusion that Esparza was an alien at the time of his reentry, and the nunc pro tunc divorce decree obtained in 2010 purporting to retroactively rearrange Esparza's custody status in 1994 does not raise a reasonable doubt as to his alienage).
