Did you know that the U.S. conducts a yearly immigration lottery for people who want to come here but have no particular qualifying criteria for admission? Several million people apply for about 20,000 slots. Because of some error in the lottery process, in 2010 the government invalidated the results after the 20,000 winners had been notified. In trying to rationalize immigration policies, we must remember that those policies apply not just to those crossing the southern border from Mexico without having gone through the prescribed application procedure.
