U.S. citizens are required to enter and depart the United States on a U.S. passport. This requirement applies equally to U.S. citizens, including children, who are dual nationals. Dual national U.S. citizens may NOT use their foreign passport to apply for an electronic travel authorization (ESTA). The Department of Homeland Security routinely denies or cancels ESTAs for dual national U.S. citizens. If you are a U.S. citizen or national and live abroad and plan to travel to the United States, make sure you do so with a valid U.S. passport. If your U.S. passport is expired or expires soon, renew before your trip! Remember many countries require passports have six months validity.
