United States v. Karaouni, 379 F.3d 1139 (9th Cir. Aug. 24, 2004) (federal conviction of violating 18 U.S.C. 911 reversed, since, by checking box on an INS I-9 Employment Eligibility Verification Form next to the following printed statement: "I attest, under penalty of perjury, that I am ... [a] citizen or national of the United States" noncitizen did not thereby represent himself to be a United States citizen, as required to support his conviction of falsely and willfully representing himself to be a citizen of the United States, because no rational juror could find beyond a reasonable doubt that, by checking the box on the I-9 Form, he made a claim to be a U.S. citizen as opposed to a U.S. national and a claim to be a U.S. national, even if false, does not constitute a violation of this statute).
