Fast, Reliable Support for Your Portuguese Embassy/Consulate Appointment
If you're a U.S. citizen applying for Portuguese citizenship by marriage through a Portugal Embassy or Consulate in the US, one of the key steps in the process is preparing and legalizing your U.S.-issued documents. This includes obtaining apostilles, the official certifications that make your American documents valid for use in Italy.
At American Notary Service Center, we specialize in providing apostille services for U.S. documents required by Portuguese authorities, specifically tailored for clients applying through marriage.
What Documents Need Apostille?
Based on the requirements published by the Embassy of Portugal in Washington, D.C., applicants must present several civil and criminal documents, each properly apostilled for international use.
The most commonly required documents include:
U.S. Birth Certificate (long form, issued by the state vital records office)
Marriage Certificate (must be a certified copy from the issuing state)
FBI Criminal Background Check
⚠️The Portugal embassy may have requirements on the issuing dates of those documents, for example, within the past 3 or 6 months. Be sure to check with them before you order our apostille service.
All of these documents must be apostilled by the appropriate federal or state authority before they are accepted by the consulate.
Please order the Apostille service below and enter the number of documents. Processing times vary depending on the issuing state. You can check the current processing times here.
Certified Translation (if needed)
In addition to apostilles, the Portuguese government may require certified translations into Portuguese of each document. These translations must match the legalized (apostilled) documents and are often submitted alongside the originals at your consular appointment.
We can connect you with certified Portuguese translators experienced with consular requirements, or deliver a complete package with both apostilles and translations.
