I was reading in a travel book that if you are traveling past the border region (16 miles from the USA) you will need this thing called a FMT. Do i really need to get one? I have a US Passport. Could that be enough? I am planning on heading from the US to Panama. Maybe farther, but playing it by ear... So do I really need this, and what kind of paperwork will I need for this trip so I don't land myself in some sort of legal troubles??
-Thanks
