America has borders. You have quite strict borders, actually. Even getting a work permit in New York actually is quite a difficult thing to do. I've got to prove I've got an address. I've got to prove I have private health care. And when my work permit runs out, if I haven't left, there'll be a knock at the door, they'll put me in handcuffs and take me to JFK Airport. That's how you guys do it.
