Each document in this chain must be apostilled and translated into Portuguese.
Portugal permits dual citizenship, making Portuguese citizenship by descent an increasingly popular pathway for the large U.S.-based Portuguese diaspora.

- An unbroken chain of descent documents linking you to your Portuguese ancestor
- All required vital records must be apostilled and translated into Portuguese
