To Wild Bill Wiederhold: I have a question regarding crossing to Mexico by land walking. Can I cross with only the Green Card? Or I need a my national passport (My passport is expired) or a USA travel document along with the Green Card? I know crossing by car has no issue and returning to the USA with only the Green Card works flawlessly. Thank you
If you are a U.S. citizen or legal alien. It shouldn't be an issue as when you arrive at customs you are already in America. I've forgotten my passport once or more and not had an issue. As long as you have some sort of proof of residency. Best of luck.
