Regaining Belgian nationality

• Be 18 years of age or older
• To have one's main residence on the territory of the City of Brussels
• Have had your main residence in Belgium during the 12 months preceding the declaration, based on continuous legal residence
• Have been admitted or allowed to reside indefinitely at the time of the declaration
• Have not lost the Belgian nationality by revocation

There is an exception to the condition of residence in Belgium if you have lost your Belgian nationality because you did not make a declaration of nationality retention before your 28th birthday. In that case, the application can be made from abroad, before the head of the consular post.
