Why is it?

I heard this on the radio on America's Trucking Network:

1. Why is it, that if you cross the border into North Korea you're caught and sentenced to hard labor, etc..?



2. Why is it, that if you hike into Iran you are sentenced to prison for x years, etc..?



3. Why is it if you sneak into the United States you get a Driver's Licence, a Social Security Card, etc..?

Arsenio.
