What do I need to travel to the Bahamas?
I am traveling to the Bahamas before, I am not a U.S. citizen, but I am a permanent resident. I have a green card and a passport from another country is right or do I need a passport to travel?
Since June 2009, you will need a passport, but I just got back from there and March 6 all you needed was a birth certificate and driver's licenses if June 1st b4 you carry your green card their inputs and BC, and dl. Good luck i hope u have fun.
