Will Trump make him leave?
I know that he has some kind of work permit to star in Hollywood films, but do you think that the U.S. Government might put him on the bus to Tijuana anyway?
If Trump gets elected and actually starts deporting people en masse (which BTW I seriously doubt that he will), there might be some confusion as to who can stay and who can't. Mr Luna might forget his wallet the day the Cops show up at the restaurant he's eating in, and he gets a quick one way ride across the border. More likely, he and other prominent Mexican citizens in America might just leave out of principle, a show of solidarity with their countrymen.
It's weird times we live in.
