United States v. Elzahabi, 557 F.3d 879 (8th Cir. Mar. 5, 2009) (federal conviction of knowingly possessing and using a fraudulently obtained immigration document in violation of 18 U.S.C. 1546(a), affirmed because evidence was sufficient to support conviction, rejecting claim that prosecution failed to prove that marriage was invalid), following Lutwak v. United States, 344 U.S. 604, 611-612 (Feb. 9, 1953) ("We do not believe that the validity of the marriages is material. No one is being prosecuted for an offense against the marital relation.... [W]hen one of the aliens stated that he was married, and omitted to explain the true nature of his marital relationship, his statement did, and was intended to, carry with it implications of a state of facts which were not in fact true.").
