A. Your having been cited won’t keep you from becoming a U.S. citizen. You should note the citation on form N-400, Application for Naturalization, where it asks “Have you EVER been arrested, cited, or detained by any law enforcement officer . . .” Traffic citations that do not involve alcohol, drugs or vehicular homicide do not bar naturalization. President Trump is doing everything he can to keep immigrants from getting U.S. citizenship, but even he can’t change this rule. The N-400 instructions says you need to present documentation of traffic offenses only if the fine was $500 or more, involved alcohol or drugs, led to an arrest or seriously injured another person. I suggest you bring proof that you paid your fine, even if the rules don’t require it, in case the immigration officer requests it.
