Michigan Gov Rick Snyder has something to say to foreign students and entrepreneurs wary of settling in the US, where tough new laws in Arizona, Alabama, Georgia, and South Carolina aimed at illegal aliens have also led to an exodus of legal workers: Come to Michigan. While Republican presidential candidates Mitt Romney and Newt Gingrich spar over who will more vigilantly guard the border, Snyder has assigned state agencies to persuade skilled foreigners to put down roots in Michigan. Snyder's program will promote Michigan abroad as a friendly place for entrepreneurs to open businesses, and match employers to foreign students with training in science and engineering. He's betting an influx of immigrants to the state, which led the nation in unemployment for much of the last decade as the auto industry collapsed, will help revive the economy.
