Question by d y: Cruise documentation?
My mom wants to go on a cruise. She is born in China, so she moved here (USA) 25 years ago. She has an valid US Alien card (green card) and a picture NYS ID card. She is NOT a citizen, so dont advise about US passports. Can she go to cruise ships to Carribeans? I need personal experience advice rather than website links.

U.S. Resident Aliens are required to present, in addition to a valid passport, a current and valid Alien Resident Card.
