The family reunification status is the best option suited to your requirement. Family members of a person with a residence permit (obtained through the D7 visa) are also entitled to residence permits, based on the family reunification status.
Family reunification works in the following way: a person who obtains a residence permit to live in Portugal (whether for study, work, investment, etc.) is entitled to regroup close relatives or those under their responsibility. After placing the order (if everything is fine), family members are also allowed to live in the country and can even work if they want. Who is entitled to family reunification in Portugal? Family members of a person who have obtained a residence permit to live in Portugal are entitled to reunification. It is incumbent upon the holder of the right to family reunification to request SEF the entry and residence of his/her family members, whenever they are located outside the national territory. Whenever family members are in national territory, family reunification may be requested by them or by the holder of the right. Not everyone in the family is entitled to request family reunification. For the SEF (Foreigners and Borders Service), the body responsible for requests for family reunification and residence permit, the family members who can request reunification are: spouse or partner of the person who has a residence permit; minor children of the couple or one of the spouses/partners; minors adopted by the applicant or by the spouse/partner; older children of the couple or of one of the spouses/partners, as long as they are single and study in Portugal; parents of the resident or his/her partner/spouse, if they are his/her responsibility; minor siblings, as long as they are under the resident's guardianship.
