Hi ,
I'm current a F-1 student and I would like to travel to CanCun or adjacent islands. Do I need to contact ICE office before I travel or do I just need to bring my relevant document to show that I have studied in the U.S? If yes, what do I need to bring with me to travel?
My uncle has a green card, and he would like to travel outside The U.S like
Caribbean or adjacent island or mexico, what does he need to do?
