what type of passport do american citizens have?
By law, a valid unexpired U.S. passport (or passport card) is conclusive (and not just prima facie) proof of U.S. citizenship, and has the same force and effect as proof of United States citizenship as certificates of naturalization or of citizenship, if issued to a U.S. citizen for the full period allowed by law.here are five types of passport booklets; as well, the Department of State has issued only biometric passports as standard since August 2007, though non-biometric passports are valid until their expiry dates.
