What gets translated on a Mexican birth certificate for USCIS?

Everything on your Mexican birth certificate gets translated, front and back. That includes the registry details, your name exactly as written with both surnames, the seals and signatures (marked where they appear), any notes in the margin or on the back and, if your copy has one, the CURP (Mexico’s population registry code). USCIS asks for a full translation and does not accept a summary. If you were looking for your birth certificate in English, this is what you file: the Mexican acta together with its certified English translation.

A Mexican birth certificate translation doesn’t replace the certificate: the two go in together. For USCIS, the federal agency that handles immigration applications, you send a legible copy of your acta (the Mexican birth certificate), not the original, unless the form instructions or the regulations ask for it. The full English translation and the translator’s signed certification go with that copy (8 CFR 103.2(b)(3) and (b)(4); USCIS).

Current USCIS form instructions, such as those for Form I-485 (the application to adjust status), add that the certification must include the translator’s signature, printed name, signature date and contact information (I-485 instructions).

Immigration court also asks for an English translation with the translator’s signed certification (8 CFR 1003.33). For an immigrant visa interview at the U.S. consulate in Ciudad Juárez, civil records already in Spanish, such as your acta, need no English translation (consulate instructions).

Which kind of acta do you have: formato único, a book copy or an online print?

Whichever you have, it gets translated in full. The U.S. State Department describes these formats and notes that certificates in older formats remain valid:

Format	How to recognize it	When issued	Source
Older formats	Many designs: there were more than 196 different formats	Until 1999	State Department
Sepia security paper	Printing standardized on sepia-colored security paper	From 2000	State Department
Formato único (single format)	One national format on green security paper, with the CURP, a print folio and QR codes	From 2016	State Department; SEGOB
Online print	Plain white paper, in color or black and white, with a QR code and an electronic identifier to verify it online	From 2018	State Department

If yours is a book copy (a copy of the registry page where your birth was recorded), it may not look like any of these. It gets translated the same way, with everything on it.

According to the same State Department page, the “certificado de nacido vivo” (the live birth certificate used to register a baby) is not a birth certificate and does not replace one.

If you printed yours at home, each office decides whether it accepts that copy. The details are in our answer to is an acta printed from the internet valid?

Which parts of the acta get translated?

All of them, on both sides. That is what USCIS requires for a document in Spanish: a translation of the whole document, certified as complete and accurate (8 CFR 103.2(b)(3)).

The USCIS Policy Manual adds, “A summary of a document prepared by a translator is unacceptable.” The American Translators Association (ATA), a professional association, warns that leaving out “fine print, headers, or back-page stamps frequently triggers rejection” (ATA, 2026).

On a Mexican acta, that includes:

• The heading and registry details, such as the state, municipality, oficialía (the civil registry office), acta number and registration date.
• Your name with both surnames, your date and place of birth, and your sex.
• Your parents’ details and, if listed, those of your grandparents and the witnesses (Federal Civil Code, arts. 58 and 59).
• The CURP, the print folio, the electronic identifier and the QR and verification codes, whichever your copy has (SEGOB; State Department).
• The certification by the official who issued the copy, with its seals and its signatures, handwritten or electronic.
• Margin notes and anything on the back.

All of it goes into the certified translation of your birth certificate we deliver.

What is the CURP, and how does it appear in the translation?

The CURP, short for Clave Única de Registro de Población (Unique Population Registry Code), is the code Mexico uses to register each person individually. The translation copies it exactly, character by character, and never translates or corrects it.

According to Mexico’s National Population Registry (RENAPO), the CURP is used to register both people living in Mexico and Mexicans living abroad. It has 18 characters, letters and numbers: the first 16 come from the data on your birth certificate or other identity document, and RENAPO assigns the last two (SEGOB).

If the CURP on your acta doesn’t match the one on another of your documents, tell us before we certify. The translation shows the one on the acta.

What are margin notes, and do they get translated?

Margin notes, or anotaciones marginales, are entries the civil registry adds to your acta to record something that happened after your birth was registered. Yes, they get translated. They are part of the document, and the USCIS rule calls for a full translation.

Mexico’s Federal Civil Code, for example, calls for a note when a child is legally acknowledged after the birth was registered (arts. 82 and 83) and when a judge sends the registry a ruling, such as a divorce (arts. 131 and 132). It also calls for one when a judge rules on a case to correct the record, even if the ruling denies the correction (art. 138).

A note may also be on the back, so send us both sides even if you think the back is blank.

What a note means for your case is a legal question for an immigration attorney or an accredited representative.

What if your acta has an error or your name doesn’t match your passport?

The translation shows the acta as it is, error included. It has to be complete and accurate (8 CFR 103.2(b)(3)), and a translator can’t correct a civil record.

Only Mexican authorities can correct the acta. Under Mexico’s Federal Civil Code, for example, typing, spelling and other errors that don’t affect the record’s essential data are handled through an “aclaración” at the civil registry (art. 138 Bis), and any other correction takes a court ruling (art. 134).

The procedures available depend on the state where your birth was registered. On miregistrocivil.gob.mx, Mexico’s National Civil Registry Platform, you select a state to see the procedures available for it, and you check on a request you made on the platform with a Llave MX account. Ask the civil registry of the state where you were registered which procedure applies to your acta.

If your name is spelled differently on the acta and on your passport, tell us. It’s part of what we check before certifying. Whether that difference matters for your case, or whether to correct the acta before you file, is a question for an immigration attorney or an accredited representative.

What this guide does not answer

This guide does not tell you whether your acta works for your case, whether to correct it before you file, how to handle a name change, or what a margin note means for your application. That is legal advice, and it comes from an immigration attorney or an accredited representative of an organization recognized by the Department of Justice.

EOIR, the Justice Department office that runs the immigration courts, publishes the roster of recognized organizations and accredited representatives.
