If you are a Mexican Citizen, is it now possible to get a Mexican Passport without leaving the United States. The Mexican Government saw a need for this service, and has created a much easier process for its citizens to get their passports. If you don’t have a birth certificate, all you have to do is visit the nearest Mexican consulate in your state. There you will be able to apply for a copy of your birth certificate. After you receive that birth certificate, you can then use it to apply for a passport at the same consulate office.
