Which family members qualify for reunification with a Portuguese resident?

Portuguese rules define a clear set of qualifying relatives. The most common are the spouse and minor children of either spouse, including lawfully adopted minors, and a registered partner in a relationship comparable to marriage.

Beyond that, single adult children who are dependent and studying at a Portuguese institution can qualify, as can dependent first-degree ascendants such as parents, and in some cases minor siblings under the sponsor's guardianship. Each category has its own dependency and documentary tests, so confirm which applies to your relative before applying.
