For those ports your friends will just need a picture ID (drivers license) and a certified copy of their birth cirtificates. I would highly recommend though that they apply for passports, its the best identification you can have these days. You should still have time and it sure makes traveling easier. Here is a link to all the information on getting one:
Thanks, I always encourage it too, plus our trip is almost a year away, policies could be more strict by then. I just know that at $70/person including the picture, someone's not going to want to bother, so I thought I better check.
This wil be my first cruise. We are going to the Southern Caribbean & we are leaving on 04/15/02. I have a passport, but it expires in June of this year; I don't think there is no time to get another one. Is that going to be a problem?
The rule is that U. S. citizens need both (1) proof of citizenship and (2) proof of identity for travel to the Caribbean, Bermuda, Canada, or Mexico. A passport is the only document that meets both requirements, and is definitely preferred by immigration officials. If you don't have a passport, you can use an official birth certificate (with raised seal) or naturalization papers for proof of citizenship and any identification card issued by a government agency that bears your photograph, such as a driver's licence, a military ID card, or a student identification card issued by a state college or university, for proof of identity. Note, however, that you will need two documents if you don't have a valid passport.
If I remember correctly, an expired passport is acceptable as proof of identity but not as proof of citizenship.
