I am a Chinese holding J-1 Visa in US and will stay in US for 10 months. I want to take a cruise trip during this winter vacation to some of the Bahamas islands arranged by the cruise company Carnival. I am not sure if I need seperate visa from Bahama Embassy in US for the trip? I will only follow the cruise ship routine and spend 5 days. My wife is going to come to join me(with J-2) and share the trip with me. Is she required to obtain the visa from Bahamas Embassy in advance? Please kindly help me in this in urgent. Thanks a lot!
