Brazilian and European Portuguese are different enough that using the wrong variant on a USCIS or court submission can cause problems. Portuguese has around 260 million speakers — about 80% in Brazil, the rest mainly in Portugal, Angola, Mozambique, and Cape Verde. We match each project to the right variant: Brazilian Portuguese for the bulk of US immigration work, European Portuguese for Portuguese-government documents and EU citizenship applications. The two share an alphabet but have distinct legal vocabulary, spelling conventions, and signature blocks. Major US Portuguese-speaking communities sit in Massachusetts, Rhode Island, South Florida, New Jersey, and California.
