We need to start another thread "Lazy A$$ Americans"...........I believe that if the aliens (not ET) would come here and get the drivers license that would defeat their purpose of coming over here illegally. It would require to much information on their part. As well as a photo and finger printing. They would not go for it. My opinion.
People who have money would not be coming here illegally (under normal curcumstances). If I was wanting to benefit from coming here and earning money, then I would not want to leave a "paper trail". I would want to come here - earn money - send it/take it to my family, that's it.
