# Mexican birth certificate translation, field by field

A Mexican birth certificate translation for USCIS is a full English version of the acta de nacimiento with a signed statement that it is complete and accurate and that the translator is competent[1]. Translate every field, including the CURP, the margin notes and the certification, and keep names and numbers exactly as written.

## What is on a Mexican acta de nacimiento

Mexico's civil registries issue birth certificates in one national layout, the Formato Único, which the national population registry (RENAPO) describes field by field in its manual[2]. It lists only the registered person and the parents, with the CURP of each, and it can be checked online[2]. Older certificates follow earlier state layouts. The specimen at the top of this page is one of those, with grandparents and witnesses, so match the fields to your own copy.

## Rules for translating it

- Translate the whole document, front and back, including stamps, seals and the certification text. USCIS asks for a full English translation[1].
- Keep names exactly as written, with both surnames and every accent. A name is not translated or anglicized.
- Copy numbers as printed: the CURP, the identifier, the book and entry numbers and the validation number.
- Spell out the month in every date, so a reader cannot take 06/05/1994 for June 5 when the certificate means May 6.
- Describe what cannot be translated in brackets, such as [seal], [QR code] or [illegible signature].

## How to translate a Mexican birth certificate with LoreAI

1. **Get the certificate as a PDF or photo.** A copy requested online through Mexico's national civil registry platform starts by choosing the state where the birth was registered[3]. A scan or a phone photo of a paper copy works too.
2. **Upload it and choose English.** LoreAI reads the scan, translates it from Spanish and rebuilds the form's sections as Word tables.
3. **Check every field.** Check the CURP, names, dates and margin notes against the original one by one. Correct the Word file where needed.
4. **Add the signed statement.** The person who checked the translation signs a certification. The [certificate of translation template](https://www.loreai.org/certificate-of-translation-template) has the wording.

## Can I translate it myself?

The USCIS rule asks for a translator who certifies the translation as complete and accurate and certifies that they are competent in Spanish and English[1]. It does not exclude the applicant. USCIS's director has quoted agency guidance that anyone, including family members, can provide a translation as long as they certify their competence[4].

Ask a bilingual friend or relative to check and sign the LoreAI draft if you want someone other than the applicant to translate. That second reading also catches a swapped surname or a misread digit in the CURP.

## Notarization and apostille

Neither the USCIS translation rule nor its filing instructions mention a notary or an apostille for the translation[1][5]. Send a legible copy of the certificate with the translation, not the original, unless USCIS asks for the original[5]. If a court or a foreign office asks for an apostille, follow that office's instructions.

## Is there a template?

LoreAI builds the English version from your own certificate, so the fields match your document instead of a generic form. The [birth certificate translation template](https://www.loreai.org/birth-certificate-translation-template) has the usual fields in a blank layout you can fill in by hand. The [Spanish to English guide](https://www.loreai.org/birth-certificate-translation/spanish-to-english) explains common terms on other Spanish-language certificates.

## Questions people ask

### Do I need to translate the back of the certificate?

Yes, if anything is printed or stamped on it. USCIS asks for a full English translation[1], and the back of the national format carries a QR code and the state's coat of arms[2].

### Should I translate the CURP?

No. Copy the CURP exactly and explain it once, for example as Unique Population Registry Code[2].

### Does LoreAI keep both surnames?

LoreAI keeps names as written, including both surnames and accents. Check them against the original before anyone signs.

### Is this a certified translation?

No. LoreAI gives you the English Word file. A person who knows Spanish and English checks it and signs the statement.
