Alright, I see what you meant. Utah's law isn't really being implemented, though, since it's being challenged in court. There's no conceivable way I can see this happening unless the Federal Government gives its express permission--something that would be absurdly unreasonable from a legal standpoint simply because states haven't ever had the power (as far as I know, so correct me if I'm wrong) to grant individuals permission to reside legally in the United States (since such individuals would be entitled to freedom of movement around the country due to their quasi-legal status).
