Acquisition of nationality relates the procedure of obtention of nationality for persons aged 18 years old. For an adult, declaration of nationality is the main procedure to become Belgian. It’s a relatively swift procedure, which takes about 6 months if there’s no opposition.
Since January 1st 2013, social integration and economic participation conditions are often requested. Therefore, nationality can be refused if basic conditions are not met or if serious personal events have occurred. Judicial appeals are then possible. For all requests, you must :
- At the time of declaration : be authorized to indefinitely stay in Belgium..
- During the years preceding the declaration : possess stay permits for more than 3 months (electronic cards, former “white” or “yellow” cards). “Short stays” are not taken into account (for instance, registration certificates).
- For Europeans, their family members and for refugees, the period between request filing and recognition of rights is assimilated to a long stay (more than 3 months). All stay permits during this period are allowed (annex 19, 19ter, 25, 26, registration certificate). Be careful, this doesn’t apply in case of family regrouping with a Belgian citizen.
