Did you know that through the surname it is not possible to obtain Portuguese Nationality? It's a shame! Because my last name is Rosas, uncommon in Brazil, and very common in Portugal. To obtain Portuguese Citizenship we need to be a descendant of Portuguese and obtain the birth certificate (birth certificate) of the relative in Portugal. And for that, you have to know exactly who the Portuguese is in the family.
Who is entitled to Portuguese Citizenship: 1 - Child; 2 - Neto(a); 3 - Great-grandson; 4 - Reacquisition of Portuguese citizenship: If you lost Portuguese citizenship (you opted for Brazilian nationality when the law did not allow you to have both). 5 - Wife of a Portuguese citizen; 6 - Married for more than three years with a Portuguese citizen; 7 - He has lived in a stable union for more than five years, with a Portuguese citizen (Necessary to prove a link with Portugal); *To file this process it is necessary that the Stable Union be recognised by a Brazilian judicial judgement and, sequentially, be reviewed and confirmed by the competent Portuguese court. To carry out such review/confirmation, the applicant must hire a lawyer directly in Portugal (or with representation in Portugal). 8 - Descendant of Portuguese Sephardic Jews (Necessary to prove link with Portugal); 9 - Minor children born on a date prior to the naturalisation of father or mother by topic 2 above are entitled to acquisition by naturalisation. The process is similar to topic 2, but with different article and requirements. *It is necessary to prove link with Portugal; 10 - Nationality Conservation: Born in a former Portuguese colony when it still belonged to Portugal. To apply for it, it is necessary to be a child or grandchild of a Portuguese national (by birth or by assignment) and to have been born on a date prior to the proclamation of independence of that former colony, that is, while that country still belonged to Portugal.
