Deep dives
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.
British Nationality Act
British nationality law is famously intricate. Crown service, consular registration, and double-descent (grandparent) routes each open under different sections of the BNA 1981. We map your exact fact pattern to the right section.
