PASSPORT NOTE: At least two blank passport pages are required when traveling to South Africa. If traveling to multiple countries throughout Africa, make sure that there is one blank passport page available for a stamp from each
additional country that you will be visiting.
(PLEASE NOTE: Amendment pages are not considered valid passport pages.)
Some countries require that your U.S. passport be valid at least six months or longer beyond the dates of your trip. If your passport expires before the required validity, you will have to apply for a new one. Please check with the embassy or nearest consulate of the country that you plan to visit for their requirements.
