Cruise vacation and US immigration

Your inquiry is a bit unclear: will the cruise only travel to Puerto Rico or the carribean?

A "close circuit" cruise sailing directly to the P.R., which is a "US territory" is considered "domestic travel" and you will not have to undergo Immigration inspection upon return. If, however, either on the way to and/or from San Juan, the cruise ship will stop in any other island that is not US territory, you will then need to undergo Immigration inspection, and as such will need a valid visa stamp on your passport with which to be readmitted back into the USA.

I agree with my colleagues. Contact a US immigration attorney prior to your departure to discuss your cruise itinerary and risks of re-entry to the US.

I think you should really ask the cruise company this question as none of us know your exact itinerary. However, and I'm certainly no expert on this, I've taken 6 to 8 (quick guess on my part) in the past and I was always under the impression that they were "required" to make a stop in a foreign port of call. Again, not an expert on the laws concerning what a cruise company must do and you should really just check with the cruise company. Oh, and there are message board forums dedicated to cruse vacations. Good luck and bon voyage.
