Can anyone tell me if they let a U.S. citizen travel to the U.S. with an expired passport? My mother just realized her passport expired this 23rd of August and she has a flight for the 13th of september. From what I've been told, to renovate a passport now at the Consulado takes approx. 3 weeks to a month, so there's no time for that. Some people have told me they would probably let her pass, but I'd like to hear if anyone has had the actual experience.
