WHAT WE TRANSLATE
The Portuguese Birth Certificate (Certidão de Nascimento)
A Portuguese birth certificate is a Certidão de Nascimento drawn from the assento de nascimento held by any Conservatória do Registo Civil, and today it is most often ordered online through Civil Online or gov.pt rather than at a counter. Always request the cópia integral (full copy), which reproduces the complete register entry plus every averbamento — the marginal annotations added later for marriage, divorce, name change, adoption, or death — instead of the short narrative certidão de teor. Entries from before the 1980s were handwritten into bound registry books (livros de registo) and can be hard to read, needing careful transcription. Portugal also issues the multilingual "modelo internacional" (CIEC Convention 16) form, but USCIS still requires a full English translation with a signed Certificate of Accuracy under 8 CFR 103.2(b)(3). Because Portuguese nationals typically carry two to four surnames — usually the mother's line before the father's — we preserve the exact name order and every accented spelling so an I-130 or I-485 adjudicator matches your identity cleanly across filings.
WHO ISSUES IT
Where Your Portuguese Birth Certificate Comes From
In Portugal, civil-status records come from the Conservatória do Registo Civil (Civil Registry Office), under the Instituto dos Registos e do Notariado — IRN (Institute of Registries and Notary Affairs), Ministério da Justiça. Portugal has been a party to the Hague Apostille Convention since 1969, so a single apostille issued by the Procuradoria-Geral da República (Attorney General's Office) authenticates a Portuguese public document for USCIS.

USCIS REQUIREMENTS
How USCIS Wants Your Portuguese Birth Certificate Translated
For your Portuguese birth certificate, USCIS requires a complete English translation of everything on the page — the issuing office’s details, seals, and any marginal notes included — plus a signed certification of accuracy under 8 CFR 103.2(b)(3). Machine translation cannot sign that certification. We reproduce the document's exact layout so an officer can compare it line by line against your Portuguese original.
WATCH OUT FOR
Common Portuguese Birth Certificate Pitfalls
Portuguese birth certificates carry parent names and often marginal notes (later corrections, adoptions, or legitimations); USCIS compares them against your passport and forms, so an omitted annotation or a transposed surname is one of the most common causes of a Request for Evidence.
Native Portuguese Specialist
A native speaker of your document's language handles it — not a generalist or a machine.

FAQ
Frequently Asked Questions
How much does Portuguese birth certificate translation cost?
A standard Portuguese birth certificate is typically $15-25 total, certified and formatted, delivered in 24-48 hours. Pricing is $0.05 per word; longer or multi-page documents are quoted exactly before you pay.
Is your Portuguese birth certificate translation accepted by USCIS?
Yes. Every translation includes a signed Certificate of Accuracy meeting 8 CFR 103.2(b)(3). If USCIS rejects it citing the translation, we correct it free and reimburse your resubmission fee.
Does Portugal use apostilles for USCIS documents, or do I need embassy legalization?
Portugal has been a Hague Apostille party since 1969, so an apostille from the Procuradoria-Geral da República is all the authentication USCIS needs — there is no U.S. embassy or consular legalization step. You then add a certified English translation.
