Mexican Nationality by Birth (Article 30)

Mexican citizenship by descent, known as Nacionalidad por Nacimiento (Nationality by Birth), is a right for anyone born abroad to at least one Mexican parent. Following the 2021 Constitutional Reform, this right now extends indefinitely across generations, provided each generation is officially registered. You can complete this process at a Mexican consulate in your country of residence or at a Registro Civil (Civil Registry) office if you are currently in Mexico.

Route 1: Applying at a Mexican Consulate (Outside Mexico)

1. Prepare Your Documents: Gather your long-form birth certificate and your parent’s proof of Mexican nationality (Mexican birth certificate, valid passport, or Matrícula Consular—a consular ID card). If your birth certificate is from a country other than where the consulate is located, it must be apostilled (a form of international authentication) or legalized.
2. Translate Non-Spanish Documents: Any document not in Spanish must be translated by an official translator.
3. Request an Appointment: Book an appointment through the MiConsulado booking portal.
4. Submit for Pre-approval: Many consulates require you to email scanned copies of all documents before your appointment to ensure there are no name discrepancies. The names on your birth certificate must match your parents' Mexican documents exactly.
5. Attend the Registration: Visit the consulate for your appointment. If you are an adult, you will sign the registry yourself. If the applicant is a minor, both parents must usually attend. You may need to bring two witnesses with valid IDs, though some consulates now provide staff to act as witnesses.
6. Receive Your Certificate: Once the Acta de Nacimiento (Mexican Birth Certificate) is signed and registered, you are officially a Mexican citizen. You can usually walk out with a certified copy the same day.

Route 2: Applying at the Civil Registry (Within Mexico)

1. Apostille and Translate: Before traveling to Mexico, ensure your foreign birth certificate has an apostille from the issuing authority (e.g., the Secretary of State in the US state where you were born). Once in Mexico, have it translated by a court-certified translator (perito traductor).
2. Visit the Registro Civil: Go to the Registro Civil office in the municipality where you are staying.
3. Inscribe the Foreign Birth: You will apply for an Inserción de Acta de Nacimiento Extranjera (Insertion of a Foreign Birth Certificate). The office will verify your parent's Mexican birth record in the national database.
4. Obtain Your CURP: Once registered, you will be issued a Clave Única de Registro de Población (Unique Population Registry Code), which is essential for all legal and administrative acts in Mexico.

The initial registration of your birth and the issuance of your first Mexican birth certificate are free of charge at Mexican consulates as a constitutional right.
