The United States of America does not require exit visas. Since October 1, 2007, however, the U.S. government requires all foreign and U.S. nationals departing the United States by air to hold a valid passport (or certain specific passport-replacing documents). Even though travellers might not require a passport to enter a certain country, they will require a valid passport booklet (booklet only, U.S. Passport Card not accepted) to depart the United States in order to satisfy the U.S. immigration authorities. Exemptions to this requirement to hold a valid passport include:
The Democratic People's Republic of Korea (North Korea) requires that its citizens obtain an exit visa stating the traveller's destination country and time to be spent abroad before leaving the country. Additionally, North Korean authorities also require North Korean citizens obtain a re-entry visa from a North Korean embassy or North Korean mission abroad before being allowed back into North Korea.
