Belgium Family Reunification Options for Foreign Workers

Belgium (Koninkrijk België / Royaume de Belgique — Kingdom of Belgium) allows non-EU workers with a valid residence permit — such as a single permit or EU Blue Card — to bring their spouse or partner and minor children to live with them. Belgium tightened its rules in 2025: spouses and partners must now generally be at least 21, and sponsors must show stable income of at least 110% of the average minimum monthly income — €2,369.52 net a month in 2026 for one family member, plus €236.95 for each additional member. Applications are decided by the federal Immigration Office, and families of EU Blue Card holders benefit from a faster procedure. This EU Helpers guide explains who qualifies and how to apply — international candidates can explore Belgian opportunities through EU Helpers. Belgium is a founding member of the EU (1958), a founding Schengen state, a eurozone member since 1999, a founding NATO member since 1949 (NATO is headquartered in Brussels) and a founding Council of Europe member since 1949.

Essential Context: How Family Reunification Works in Belgium

Family reunification is a federal matter, even though work permits are regional.

Who Can Be Reunified

• Your spouse, or your registered partner with an equivalent registered partnership — generally both aged at least 21.
• Unregistered partners in a stable, long-term relationship who meet strict proof requirements.
• Your minor children, and your spouse's or partner's minor children if you or they have custody.
• Disabled adult children who depend on you, in certain cases.

Parents and other relatives of non-EU workers do not usually qualify under these rules.

Eligibility Conditions

• The sponsor holds a valid residence permit in Belgium (for example an A card based on a single permit or Blue Card).
• The sponsor has stable, regular and sufficient income.
• The family has adequate housing that meets basic safety, health and habitability standards.
• Every family member has health insurance covering risks in Belgium.
• Family members have no public-order or security issues and pass a medical check.

The two-year waiting period introduced in 2025 for some sponsors does not apply to economic migrants, so workers can apply as soon as they hold a valid permit.

Financial and Accommodation Thresholds

Income

Under the rules introduced in 2025, the sponsor must show stable, regular and sufficient means of at least 110% of the guaranteed average minimum monthly income. From 1 January 2026:

Some situations are still assessed under the earlier rules, set at 120% of the social integration income (€2,173.88 net a month from March 2026). Social assistance does not count towards the income requirement. Check which rule applies to you.

Accommodation and Health Insurance

• A registered rental contract or proof of ownership for housing that meets basic safety, health and habitability standards.
• Health insurance covering all family members in Belgium — usually through the sponsor's Belgian mutual insurance fund (mutualité / ziekenfonds).

Step-by-Step Reunification Process

1. Confirm that your income meets the 2026 threshold for your family size and that your housing is suitable.
2. Gather marriage and birth certificates, legalised or apostilled and translated where required.
3. Family members apply for a type D visa for family reunification at the Belgian embassy or consulate, or — if already legally in Belgium — file at the commune.
4. The Immigration Office examines the file; Blue Card families follow a faster procedure.
5. After approval, family members travel to Belgium and register at the commune within eight working days.
6. After a residence check, they collect their A card.

Documents Checklist

Timing: How Long Family Reunification Takes

Can Family Members Work in Belgium?

Yes. Family members admitted through family reunification generally do not need a separate work authorisation and can work with their residence card. Check the work-access mention on the card and confirm with the regional authority if you are unsure.

Children's Schooling

Schooling is compulsory in Belgium from age 5 to 18 and public schools are free. The language of instruction depends on the community: Dutch in Flanders, French in Wallonia, Dutch or French in Brussels and German in the German-speaking Community. Brussels and other cities also have European and international schools. Register children early, as popular schools in Brussels and Flanders use enrolment systems.

Renewal of Family-Member Permits

Family members renew their A cards at the commune, usually in line with the sponsor's permit. During the first years, the Immigration Office can check that the conditions — income, housing, health insurance and a genuine family relationship — are still met. Renew everyone's cards together.

Pathway to Long-Term Residence for Family Members

Family members can apply for long-term residence after five years of uninterrupted legal residence. Belgian nationality is usually possible after five years of legal residence with proof of language skills, social integration and economic participation.

Common Mistakes to Avoid

• Ignoring the age-21 rule — spouses and partners must generally be at least 21.
• Using an old income figure — the 2026 threshold is €2,369.52 for one family member, plus €236.95 for each additional member.
• Counting social assistance as income — it does not count.
• Non-legalised documents — civil documents usually need legalisation or an apostille and a translation.
• Inadequate housing — housing must meet basic standards and suit the family.
• Missing commune registration — register within eight working days of arrival.

Final Guidance

Family reunification in Belgium is open to non-EU workers from the moment they hold a valid residence permit, with no waiting period for economic migrants. Make sure your spouse or partner meets the age-21 rule, your income reaches the 2026 threshold of €2,369.52 net a month plus €236.95 for each additional family member, your housing meets basic standards and everyone has health insurance. File at the Belgian embassy or commune with legalised and translated documents, and register with the commune within eight working days of arrival. Blue Card families benefit from a faster procedure.
