Foreign nationals may naturalize after meeting a minimum residence period (usually four years), demonstrating proficiency in the Portuguese language, and fulfilling a good character requirement.Although Brazil gained independence in 1822 and Brazilian nationals no longer hold Portuguese nationality, they continue to have favoured status when living in Portugal; Brazilians resident for at least three years are eligible to vote in Portuguese elections and serve in public office there.The initial processing is done by the Federal Police, which collects the applicant's fingerprints and may request a recorded interview or additional documents.[5] The process is then forwarded to the Ministry of Justice and Public Security, which may also request additional documents, and finally publishes its decision in the Official Journal, available online.[8] If approved, a copy of this decision is sufficient proof of naturalization to obtain a Brazilian identity document or passport.Brazil only issues visas to its dual citizens in exceptional circumstances, such as for those who work in foreign government jobs that prohibit the use of a Brazilian passport.[17] Male citizens between 18 and 45 years of age are required to present a military registration certificate when applying for a Brazilian passport.The constitution also restricts the ownership and management of journalism and broadcasting companies to citizens by birth or who have been naturalized for more than 10 years.Citizenship could be lost if one was naturalized in another country or accepted employment or honors from foreign governments without the approval of the crown.Only the illegitimate child born abroad to a Brazilian mother could derive nationality from her, on the condition of establishing residency in Brazil.[42][43] In 1933, Gilberto Amado [pt] and Lucillo Antonio da Cunha Bueno, the Brazilian delegates to the Pan-American Union's Montevideo conference, signed the Inter-American Convention on the Nationality of Women, which became effective in 1934, without legal reservations.
