The Belgian Chamber of Representatives has adopted a law raising the fee for registering the acquisition of Belgian nationality from €150 to €1.000. The change, included in the programme law adopted on 18 July 2025, forms part of a broader package of budgetary measures. The new fee will apply to applications submitted after the law enters into force and will be indexed annually.
