All travelers to the Bahamas need a passport. As you arrive into Nassau Airport you will clear Bahamas Customs & 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 & Immigration before arriving at your departure gate. Please plan extra time to check in for your flight home.
