Can I bring my family on a D7?

Short answer: Yes — spouse and minor children join via the D6 family-reunification track, filed after your D7 is granted.

Once your D7 (or D8) is issued, file D6 (Reagrupamento Familiar) for spouse and dependent children. You'll need marriage / birth certificates apostilled, proof of family ties, and adequate accommodation + subsistence (multipliers apply per family member). See related items at /faq?topic=family.
