Ahoy there, Francis! Welcome, and thank you so very much for coming to see us with your question.
Disney Cruise Line does a pretty good job of providing information when it comes to
required documentation to travel, but there are a few things up in the air with your question, so let's talk about your best plan.
You should browse the many options the
Disney Cruise ships offer in terms of
itineraries, and determine which cruise you would be considering taking. Take note of where the ship goes - which countries it visits. Also, be sure to check the number of days you would be considered out of the United States.
Once you've done your browsing, selecting, daydreaming, and drooling over the many incredible options, I recommend a visit to the international student office at your university. There are a few variables with the F-1 student visa, including the initial grace period and such, that may impact traveling outside of the United States. There should be someone in the office that can let you know for certain where you stand with your ability to travel, what limitations you may have on places you'd like to visit, and what additional documents you'll need in order to cruise.
I hope this points you in a direction that helps you get into shipshape so you can sail, Francis!
