Portuguese medical translation — serving 1.4 million US Portuguese speakers
With 1.4 million Portuguese speakers in the United States — concentrated in Massachusetts, New Jersey, California, and Florida — the demand for qualified Portuguese medical interpreters is both a legal requirement and a patient safety imperative. Section 1557 of the Affordable Care Act mandates free qualified interpreters for all LEP patients in federally funded healthcare settings.
Portuguese medical translation also serves Brazil's rapidly growing healthcare sector — the largest in Latin America. Brazil's ANVISA regulatory agency requires Portuguese-language documentation for all pharmaceutical products and medical devices sold in Brazil.

Portuguese legal translation across two legal traditions
Brazil operates under a civil law system based on the Napoleonic Code, while Portugal follows the Portuguese Civil Code — both distinct from US common law. Brazilian legal terminology, particularly in corporate law, labor law, and real estate, has no direct English equivalent. Day Translations' legal team includes specialists in both Brazilian and Portuguese law.
Legal
Title VI — Civil Rights Act
Requires language access for LEP individuals in all federally funded programs. Portuguese is among the top 10 most requested languages in US federal agencies.
Court Interpreters Act
28 U.S.C. § 1827 mandates certified interpreters in federal courts. Portuguese is frequently requested in immigration courts, particularly for Brazilian and Cape Verdean nationals.
Brazilian LGPD
Brazil's Lei Geral de Proteção de Dados (LGPD) requires Portuguese-language privacy notices and data processing agreements for all companies operating in Brazil.
EU Regulatory Requirements
Portugal is an EU member state. All EU regulatory submissions must be available in Portuguese for the Portuguese market. INFARMED requires Portuguese for pharmaceutical submissions.

Business & localization
The Brazilian market: Latin America's largest economy
Brazil is the 9th largest economy in the world and the largest in Latin America, with a GDP of $2.1 trillion. Brazil's e-commerce market is the largest in Latin America, projected to reach $70 billion by 2026. Portuguese localization is essential for any company entering the Brazilian market — Brazilian consumers overwhelmingly prefer content in Brazilian Portuguese.
Portuguese localization requires careful distinction between Brazilian and European Portuguese. The two varieties differ in spelling (Brazil's 2009 orthographic reform), vocabulary, formality level, and cultural references. Day Translations' localization team includes in-country reviewers in São Paulo, Rio de Janeiro, and Lisbon.
