Holders of an EU/EFTA permit are entitled to family reunification, regardless of their family members' nationality. Qualifying family members may include the spouse, the registered partner in same-sex couples and children aged under 21. Parents and children over the age of 21 also qualify, provided they financially depend on the main permit holder. If family members of EU/EFTA nationals do not have EU/EFTA nationality, they may be subject to visa requirements when entering Switzerland before having received their family reunion permits.

Third-country national holders of a B permit are also entitled to family reunification. The main permit holder's spouse and children benefit from that right.
