There's a new passport card out now. Seems a helluva lot more convenient than the book, although I never have my passport on my person in Mexico. But I'm just wondering if anyone has one yet, and if so, if there have been any problems with Mexican officials accepting them. Would be nice to just be able to bring a copy of the card for FM-3 and FM-2 renewals, but that would be too easy, so I don't see that happening. Costs only $20 for 10 years....if you already have a passport.
