Nearly every discussion I have with someone who is opposed to immigration eventually includes my opponent saying something like this: “I am not against immigration.  I am against illegal immigration.  I have no problem if immigrants come here legally.”  I have always had a strong skepticism of this particular position.  Most anti-immigrant people are unaware how limited the options for legal immigration are.  Most anti-immigrant people are unaware of backlogs, priority dates, age-outs, one year filing deadlines, stop-time rules, and the fact that, for many people, THERE IS NO LINE.
