Travel Documents

Normally, this would be true, however the OP is a foreign citizen residing in the US. They will need their Permanent Resident Card when entering the US. This card is not necessarily a travel document, thus requiring their passport in foreign ports.

Passport is the way to go then you need not worry about oyher docs.

As a resident alien, you should have your resident alien card as well has your home country passport.

The RA card will get you back into the US. The passport will show your citizenship in the foreign ports.

Cannot hurt to get a passport and then you are covered for all trips.

A passport is always going to be your best bet. It is the only reliable and universally-accepted travel and ID document for international travel. Especially by air. Cannot travel by air without a passport. If there is an emergency with anyone, you on your trip, or with someone back home, you would need a passport to fly out of wherever you are. It's an investment that is good for 10 years... $10-$15/year, and it's a Federal ID, better than any drivers license. Only thing better is a military ID I believe. Why worry about the what if's. So much more piece of mind having a valid passport. My .02 of course...

We have purchased three waterproof carriers for our passports. But we are taking excursions from the cruiseline and when we are just hanging out at port we won't venture to far from the ship.

You do not have a US Passport so you should travel with your passport from home country. Yes you're a permanent resident with a green card but that does not replace your passport. Something goes wrong on the trip and you could have problems.

If you do not have a valid passport I would not travel. 99% of the time no problem, but that 1% will burn you. Good Luck

There's another thread on carrying your valuables.... you can get a waterproof pouch and carry it with you.. seems the best option

We always carry our passports with us. If an emergency happened and we were delayed, missed the ship and needed to fly out of the country, a photocopy of the passport wouldn’t be accepted.

There may be lockers to rent where you snorkel, but it also might be a good idea to purchase a waterproof package for it so you can wear your passport when you are in the water.
