Of all the immigration-related ideas for former President Donald Trump to go soft on, automatic green cards for college students may be the worst one at the worst time.

Trump has proposed that foreign students who graduate from American universities should “automatically” get to stay in the country. “You graduate from a college, I think you should get automatically as part of your diploma a green card to be able to stay in this country, and that includes junior colleges too.” He said he would address this problem “on day one.”
