Residente Permanente

Thanks for the input, but the consulate is not open today, nor would I have enough time to deal with it except for getting it resolved at the airport and allowing extra time for that. At the very least, I have a valid U.S. passport and should be able to pass through at the airport with that...

Aren't you good for 6 months jf you just enter as a tourist? Then try straightening out the mess while you're in Mexico? Just asking.

Since the border is supposed to be closed to tourists crossing on foot or in vehicles, he may find problems crossing from San Diego to Tijuana. Having a migratory status of Residente should open doors that are closed to others.
