03 · Process
Step by step
Book on MiConsulado
Civil registry requires an appointment: citas.sre.gob.mx or 1 (424) 309-0009.
Attend with the three documents
One parent or the person themselves is enough. A special power of attorney is accepted.
Receive the certificate
It takes about an hour; the legal maximum is 15 calendar days. The first certified copy is free.
04 · Booking
Appointments
Booked on MiConsulado, like other civil registry services. If the person cannot travel, the guidelines allow remote registration with prior authorisation from the consular services directorate.
ConsulMap is an independent directory. It neither manages nor sells appointments: this button opens an external official site.
05 · Your case
Who it applies to
- People born in the US (or another country) with at least one Mexican parent.
- It can be done by the person, either parent or someone with a legal interest.
- A parent who is a minor may appear on their own.
06 · Avoid a repeat visit
Common mistakes
- Following old lists that ask for witnesses, a long-form certificate or both parents: the 2024 guidelines and 2025 protocol do not require them. If your consulate asks for more, ask which rule it relies on.
- Confusing this registration with a US “dual citizenship” procedure: US citizenship is not affected.
07 · About this guide
Scope of this guide
Article 30 of the Constitution makes Mexicans by birth those born abroad to a Mexican father or mother. Birth registration at the consulate records that person in the Mexican civil registry and gives them a Mexican birth certificate, which they can then use for a passport, consular ID or CURP. The head of the consulate carries it out as civil registry judge.
Frequently asked questions
How much does Mexican dual nationality cost?
Birth registration is free, and so is the first certified copy. Additional copies cost USD 20 in 2026.
Do both parents need to attend?
No. Under the current guidelines, either parent, the person themselves or someone with a legal interest may do it.
Must the US birth certificate be apostilled or translated?
The consular civil registry guidelines do not require it. Confirm with your consulate when booking.
