U.S. Citizens may use one of the following for entry into Mexico:
• Valid Passport: This is the most recommended document - secure and convenient.
• Certified Birth Certificate: (hospital certificate is not acceptable). A birth certificate must include your given name and surname, date and place of birth, date the birth record was filed, and seal or other certification of the official custodian of such records (usually the Department of Health Services in the city where you were born).
Brides will have an easier time if tickets are issued in their maiden name to match their documents. For U.S. airport security purposes the name on the driver's license and the name on the ticket must match.
Women traveling with tickets in their married name whose driver's license (or state issued ID) is in their married name, but who are using a birth certificate as proof of citizenship will be fine as long as the first name and date of birth on their driver's license and their birth certificate match.
Natural U.S. Citizens born outside the United States may use a Certificate of Citizenship, a Report of Birth Abroad, a Consular Report of Birth (Form FS-240) or Certification of Birth (Form DS-1350 or FS-545).
U.S. Naturalization: If you claim citizenship through naturalization you may use your Certificate of Naturalization or Certificate of Citizenship or laminated Naturalization card. Note: Some airlines/charter companies may still accept the Notarized Affidavit of Citizenship or possibly a Voters Registration Card.
