Millions of foreign visitors who came to the United States on legal visas, and who had to register with our government to get those visas, are now still in the United States after their visas have expired, and our government isn't doing much to try to apprehend them (if they even know where they are because many of these people have moved or are using aliases to avoid getting caught). Anyway, law enforcement knows where many illegal aliens can be found right now (standing on street corners in groups of 25-50 looking for work in most of our large cities) and yet these illegal aliens aren't being rounded up and deported.
Yesterday, was on the way home from work. Saw a pick up truck pull over to the side of the street. out of it came 4 guys, all very non assimilated in appearance. Place they were dropped off is the same as where they would have been picked up early in the morning. In all border states, this is common.
