Ok I have a valid passport but I have misplaced it. However, I have a photo of it, which shows the relevant info. I have plans to summer in Ajijic, and can't seem to get an appointment at a US Passport Agency due to Covid. I was thinking of applying for the FMM online using all of my valid information. When I cross the border do you think that the Customs and Immigration officials in Mexico would allow me passage. I do have my old expired passport. If I wasn't trying to get the TIP for driving my car I wouldn't worry about it. Any thoughts and suggestions would be greatly appreciated.
