In Belgium, the Brussels-Capital Region constitutes the main gateway for international migration. Like everywhere in Europe, the challenge of immigration and in particular what happens afterwards, namely the integration of new immigrants in the host society, is particularly palpable in Brussels. Within the Belgian federal state, the federated entities have implemented different integration policies. Recently, these policies have experienced major upheavals, especially in Brussels where the result raises questions. Different (and possibly competing) institutions are competent, and today there are two civic integration programmes in the same territory: one from the Dutch-speaking community and the other from the French-speaking community. The aim of this article is to examine these policies by placing them in the particularly complex institutional context of Brussels. This involves studying and understanding the institutional labyrinth in which these policies exist, as well as describing them in order to compare them. This institutional puzzle has consequences for the stakeholders, i.e. the authorities and the migrants themselves.
