Some of the destinations will require you possess a visa for entry. If you do need a visa, you can contact a facility that handles visa processing or contact the consulate of the embassy or consulate of the country you plan to tour. A passport will also be needed if your travel plans take you out of the U.S. The expiration date on the passport should be good for 6 months after the end of your trip. Make sure you have a government-issued I.D., such as a driver's license, if you plan to travel inside the U.S. It also helps to carry a copy of your birth certificate.
