Two Years Before a Spouse May Follow, and the Money Is Measured Against a Collective Agreement From 1988
Answer
The general rule applies to you
No exception is recorded for citizens of Mexico on this topic. That is the answer, not a gap - everything below is the rule you get, unchanged.
116 exceptions recorded across 45 countries · none match Mexico to Belgium · Residency through marriage
Family reunification with a third-country national in Belgium is in article 10 of the Act of 15 December 1980, and it is conditional in four separate ways. The sponsor must hold an unlimited right of residence and have been admitted or authorised to stay for at least two years - one year if the family ties already existed before the sponsor arrived, and no waiting at all where only children are joining. Both spouses must be over twenty-one. The sponsor must show sickness insurance, housing considered normal for a family of comparable size, and stable, regular, sufficient means, which article 10, § 5 fixes at 110 per cent of the guaranteed average minimum monthly income under article 3 of collective agreement no. 43 of 2 May 1988, plus ten per cent for each further dependent. The family of a Belgian is not in this article at all: article 40ter puts them in the Union chapter, and which half of that article applies turns on whether the Belgian has lived in another member state.
At a glance
- How long the sponsor must already have been here
- Two years, or one if the family ties predate the sponsor's arrival, or none if only children are joining
Article 10, § 1er, first paragraph, 6°, of the Act of 15 December 1980.
- Minimum age of both spouses
- Over twenty-one
Article 10, § 1er, first paragraph, 6°, a).
- Income threshold
- 110 per cent of the guaranteed average minimum monthly income, plus ten per cent for each further dependent
Article 10, § 5, first paragraph. The reference is to article 3 of collective labour agreement no. 43 of 2 May 1988, which the Act does not reproduce.
- What does not count as income
- Integration income, the family allowance supplement, social assistance and family allowances
Article 10, § 5, second paragraph, 2°. Unemployment benefit counts only if the sponsor can show they are actively looking for work.
- A spouse who arrived as a spouse, sponsoring in turn
- Two years of regular residence first
Article 10, § 3, which exists to stop reunification chaining.
- A polygamous sponsor
- No second spouse while another is already in Belgium
Article 10, § 4.
- When the stay stops being limited
- After five years, if the article 10 conditions are still met
Article 13, § 1er, third paragraph. If they are not, a new limited stay is granted instead, renewable only on means and sickness insurance.
- Family of a Belgian
- Article 40ter, not article 10
Whether the Union rules or the national ones apply turns on whether the Belgian has exercised free movement.
Requirements
- A sponsor with an unlimited right of residence, admitted or authorised to stay for at least two years
- Both spouses over twenty-one
- Sickness insurance covering the risks in Belgium for the sponsor and the family
- Housing considered normal for a family of comparable size, meeting the safety and health criteria in force
- Stable, regular and sufficient means at 110 per cent of the guaranteed average minimum monthly income, plus ten per cent per further dependent
What applies to you
Nothing changes for a citizen of Mexico
We have no rule recorded that treats your citizenship differently here, so the general rule above is the one that applies to you. That is an answer, not a gap.
What the law says
«6° les membres de la famille suivants d'un étranger qui dispose d'un droit de séjour d'une durée illimitée et qui est admis ou autorisé à séjourner dans le Royaume depuis au moins deux ans. Ce dernier délai est ramené à un an lorsque les liens familiaux existaient déjà avant l'arrivée dans le Royaume de l'étranger rejoint ou est supprimé si l'étranger se fait uniquement rejoindre par les membres de sa famille visés aux c) à e):»The waiting period and its two reductions, in the sponsor's own terms rather than the applicant's.

Dutch and French are both authentic and a Justel record serves one of them; a quotation from one says nothing about the wording of the other.

Practical notes
The threshold is a percentage of a figure set by a collective labour agreement, so it moves when that agreement moves and without the Act being amended. No euro amount is stated here because the Act states none.
Article 10 was replaced in its entirety by the Act of 18 July 2025 with effect from 18 August 2025 and amended again by the Act of 16 June 2026. The text read here is the resulting article, not either amending Act.
