Portugal: US Documents Usually Need No Translation

Portugal's nationality regulation exempts documents written in English, French or Spanish from translation, so US birth and marriage records for Portuguese citizenship by descent are usually filed in English, apostilled.

Where we fit

For US documents, usually not at all, and we would rather say so. If the registrar asks for a translation, or a document is in another language, we can translate it, and the translation then has to be certified by a Portuguese consulate or a professional in Portugal.

Frequently asked questions

Do I need to translate my US birth certificate for Portuguese citizenship?

Usually not: the regulation exempts documents in English unless the registrar asks for a translation.
