All U.S. and Canadian citizens must travel with proof of citizenship, which is a valid passport, or birth certificate (complete with raised seal, not a photocopy) with a picture identification, or a certified naturalization certificate with picture identification.

Any state government issued drivers license or other form of picture identification should be acceptable.

Non-U.S. citizens who are residing in the United States are required to travel with their Alien Registration Card (Green Card) and valid passports.

All others must have valid passports and necessary visas at embarkation. You should consult with your travel agent for more information if necessary.
