Quick Facts
Eligibility
Brazil citizenship by descent is governed by Nacionalidade por filiação. Brazilian nationality passes by filiation without limit. Adoption, posthumous children, and children born abroad to Brazilian parents are all eligible. We file through the Consulado or directly with the Cartório in Brazil.
Eligibility for Brazil citizenship by descent depends on three key factors: (1) the generational distance between you and your Brazilian ancestor — most Brazilian programs cover no generational limit, but some go further; (2) whether the citizenship line was broken by naturalization in another country before the next child's birth in the line; and (3) the specific statute in effect at the time of each birth in the line.
Ancestra's written eligibility opinion addresses all three factors for your specific case, citing the exact statute and consular venue that applies. Our genealogists specialize in recovering the civil registry, parish, and consular records required to establish the unbroken lineage that Brazilian nationality law requires.
