Imagine dealing with the DMV. Only it's like 100X worse than the caricature of the DMV (here in PA the DMV is actually fine). And you have to time the arrival of your license with your job starting date, your apartment lease date, your airplane ticket, your bank account, etc.
I've been an "immigrant." I'm actually pretty sure I worked illegally for awhile, though a bit of don't ask don't tell is sometimes healthy.
