Passports Required!
In case you haven’t heard, starting tomorrow a passport is required to travel between the US and Mexico (and Canada, our 2nd wedding destination choice 
). In case you don’t have one, you can go to any post office to get your photo taken and submit your application. You’ll need to have a certified copy of your birth certificate OR an old passport.
Processing time is 6-8 weeks, so you might not want to put this off until the last minute. More details on the USPS site or the US Department of State site.
