Purush, It depends on your cruise itinerary. Are you going to get off the ship? If so, you definitely need a Visa. For US citizen and permanent resident they issue a Visa at the port of entry. You may want to check the procedure for foreign student with the F1 status. I went there last year. I loved the cruise part however; I did not enjoy my stay in Bahamas. I was devastated to return to US. Bahamas is just like Bihar when it comes to corruption and bargaining. If the vendor asks you for 50 dollars, you should offer 5 dollars. That's how bad it is. We went to the restaurant where they had “today’s special 9.99" written outside. After we finished the meal bill came for $15, I asked the waiter why I was over charged and was told, that today's special was for tomorrow, she pointed the advertisement there was a date written in a small letter for the next day. To make the long story short. You will have a great time at the ship however avoid staying in the Bahamas if possible.
