Today (4 June 2021) on the proposal of Minister of Justice Vincent Van Quickenborne, the Council of Ministers approved a draft royal decree amending the legislation on the acquisition of Belgian nationality in the context of Brexit.
The draft decree will provide for the addition of the certificate and residence permits (M-card) issued to British nationals benefiting from the withdrawal agreement under Brexit into the existing regulations relating to the acquisition of Belgian nationality, so that British citizens who are legally resident in Belgium on or before 31 December 2020 will retain the possibility to acquire Belgian nationality subject.
The project is now to be forwarded to the Council of State for its opinion.
Draft royal decree amending the royal decree of January 14, 2013 implementing the law of December 4, 2012 amending the Belgian Nationality Code in order to make the acquisition of Belgian nationality neutral from the point of view of immigration. See more (in French) here.
