n.— «In reality, 80% of foreign students who come to the U.S. to study, end up staying permanently, either by marrying an American citizen, having an American citizen anchor baby, going on to an American graduate school, or by getting a job at a shyster company that gets the person an H1B visa for life.» —“Re: Foreign Students” by Bruce R Usenet: soc.college July 21, 1996.
