Hello everyone. I recently received the official extension letter for my expired 10 year green card while I'm in the process of naturalization. It's form I 797 and gives me a two year extension. Can I travel to Mexico with this, my expired green card, and Mexican passport? I called Aeromexico and didn't give me a concrete answer. Called USCIS and was told this letter allowed me to travel. Can anyone confirm? Did anyone here went through this situation? Thanks
