Passports—Virtually every air traveler entering the U.S. is required to show a passport. Children 15 and under may continue entering with only a U.S. birth certificate, or other proof of U.S. citizenship. Bring a photocopy of your passport with you and store it separately. If your passport is lost or stolen, the copy will facilitate the reissuing process at your consulate.
