 From Nevada Public Radio, I'm Joe Shane. I'm in the state of Nevada. If you're undocumented, the path to permanent residency in the U.S. can be long, arduous, even impossible. Depending on your case, you might be required to leave the U.S. and live in your country of origin for three to ten years, and there's no guarantee you'll be allowed back in. Some people give it a shot. Others stay in the shadows and in limbo, not wanting to be separated from their families and the country they call home.
