Today's immigration news

President Obama announced today that the US would no longer deport illegal aliens age 30 who came to the country before they were 16, as long as they do not pose a security threat.  Republicans called it a political move, although you have to wonder where the votes are on this (unless I underestimate vote fraud).  Economically, the main impact will be to encourage young illegal aliens to make further investments in their own human capital, since they need not be as concerned about deportation.  But the odds of deportation now are not especially high, so the even lower odds are unlikely to be a game changer.
