Law of Return
Pursuant the Nationality Law (Organic Law No. 2/2018, of July 5), by original assignment, nationality can be sanguine (derived from Portuguese ancestors) or territorial (since the child was born in Portuguese territory), therefore they are Portuguese of origin:
For the purposes established in the paragraph, d) it is necessary to verify the existence of bonds of effective connection with the national community, which implies the recognition, by the Government, of the relevance of such ties, namely due to the sufficient knowledge of the Portuguese language and the existence of regular contacts with the Portuguese territory, and depends on non-conviction, res judicata, for the practice of a crime punishable by a maximum prison sentence of 3 years or more, according to Portuguese law.
