Exit Visa

If you live in less than a kindly, loving, free and open country, you can't just move in and out of its borders easily the way you can in the United States. Spend some time visiting North Korea, and note copiously how their own citizens have to apply months and months in advance for an exit visa to come see the happiest place on earth. (It ain't the capital of North Korea.)

And when you come back through JFK, be sure you kiss the ground of our not-perfect but oh-so-awesome country, which does not require exit visas.
