What type of travel document is required for a non-US citizen?
Non-US citizens are responsible for obtaining all documents needed in order to enter the countries to be visited or connected through, and for reentry into the U.S. If you are denied boarding for the countries to be visited or connected through, you are not eligible for a refund for missed travel services. We urge you to contact the consular offices of the countries on your itinerary, as well as the U.S. Bureau of Citizenship and Immigration Services, for complete information.
