do you have to have a passport to re enter the U.S. or will they let u through? I just need to go
down there for a brief visit to the dentist but don't want to be stuck in mexico.
- You don't need to worry about getting stuck in Mexico, if you don't have a passport, because border guards will probably not even let you through, especially if you're flying (don't know if Juarez has an airport), without a passport. -- Sapphire • (Talk) • 18:32, 15 January 2008 (EST)
