All travelers to the Bahamas need a passport. As you arrive into Nassau Airport you will clear Bahamas Customs and Immigration. Be sure your plane ticket matches your documentation. Check with the Bahamas Embassy for visa requirements if you are not a U.S. citizen. U.K. Embassies act on behalf of the Bahamas as well. As you depart Nassau at the end of your trip, you will clear U.S. Customs and Immigration before arriving at your departure gate. Please plan extra time to check in for your flight home.
