Summary

Makes it a crime to knowingly lie or use fake papers about U.S. citizenship, becoming a citizen, or alien registration. That covers lying under oath in any citizenship or naturalization matter; denying you were naturalized to avoid a legal duty; using or trying to use fake or fraudulently obtained arrival, naturalization, or citizenship documents; making false certificates or statements about someone’s oath, signature, or appearance on immigration or naturalization papers; saying you are a U.S. citizen to get federal or state benefits or to work illegally; and saying you are a citizen to register or vote. A person convicted can be fined under federal law, imprisoned for not more than five years, or both. The voting-registration rule does not apply if both of the person’s natural parents (or, for adopted people, both adoptive parents) are or were U.S. citizens (by birth or naturalization), the person lived in the U.S. permanently before age 16, and the person reasonably believed they were a citizen when they lied.
