Technically an “unincorporated territory” of the United States, it’s not much of a hassle to hop down to Puerto Rico, and not only that—but it’s an experience unlike any other in the US. There’s no other place in the world where you can experience such a wonderful blend of these two great cultures, and still be able to use a US passport.
