how do i become a citizen of portugal
Portuguese nationality law A person aged 18 or over may be naturalised as a Portuguese citizen after 6 years legal residence.[1][2] There is a requirement to have sufficient knowledge of the Portuguese language and effective links to the national community. Children aged under 18 may acquire Portuguese citizenship by declaration when a parent is naturalised, and future children of such Portuguese nationals will be considered Portuguese citizens by birth. A naturalized Portuguese citizen only starts to be considered Portuguese once the naturalization process is done. Therefore, they cannot transmit nationality to his descendants if they have already been born and are over 18 by the time the naturalizion process is finished.
