WHAT WE TRANSLATE
The Portuguese Marriage Certificate (Certidão de Casamento)
A Portuguese marriage certificate is a Certidão de Casamento, issued by the Conservatória do Registo Civil where the marriage was registered or ordered online. It covers civil ceremonies and Catholic (canonical) marriages transcribed into the civil register, and — since 2010 — same-sex marriages. Request the cópia integral so the certificate shows the property regime (regime de bens): comunhão de adquiridos (the default), comunhão geral de bens, or separação de bens, a detail USCIS officers reviewing a bona fide marriage for Form I-130 or I-751 often check. Divorce, annulment, and a spouse's death are later recorded here as averbamentos, so a full copy can carry the marriage's entire history. Both spouses' complete multi-surname names appear exactly as registered, and Portuguese spouses do not automatically change surnames on marriage. We translate the property regime, both full names, and every marginal note precisely, delivering a signed Certificate of Accuracy meeting 8 CFR 103.2(b)(3) so nothing in Portuguese remains for the adjudicator to interpret.
WHO ISSUES IT
Where Your Portuguese Marriage 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 Marriage Certificate Translated
For your Portuguese marriage 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 Marriage Certificate Pitfalls
Portuguese marriage certificates frequently carry a marginal annotation recording a later divorce or a spouse's death that must be translated, not skipped, and both spouses' names have to match their other USCIS filings exactly.
Native Portuguese Specialist

FAQ
Frequently Asked Questions
How much does Portuguese marriage certificate translation cost?
A standard Portuguese marriage 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 marriage 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.
My Portuguese certificate is already the multilingual 'modelo internacional' form. Is that enough for USCIS?
No. The CIEC multilingual (modelo internacional) certificate helps a reader, but USCIS still expects a full English translation accompanied by a signed Certificate of Accuracy meeting 8 CFR 103.2(b)(3). We translate the document as issued so nothing is left in Portuguese.
