U.S. citizens require a U.S. passport, a completed FSM Immigration Arrival and Departure Record (FSM Form 5004), and a completed FSM Customs Form to enter the FSM. The passport must be valid for at least 120 days beyond the date of entry into the FSM. The FSM Immigration Arrival and Departure Record and Customs Form are distributed by the air carrier prior to arrival at the point of entry. There is no limit to the length of time U.S. citizens and nationals may remain in the FSM.
