Can my spouse or children join me on a D4 study visa?

The D4 is a residence-type visa, so it opens a route for close family to live with you in Portugal. In practice you first secure your own residence permit, then request family reunification through AIMA for your spouse or partner, minor children and other qualifying dependants.

You will need to show suitable accommodation and enough income to support the family without relying on public funds. Family members granted reunification receive permits linked to yours, so it is important to keep your own student status and permit valid throughout.
