INTERACT - Researching Third Country Nationals’ Integration as a Three-way Process - Immigrants, Countries of Emigration and Countries of Immigration as Actors of Integration ; The fulltext pdfs are available upon request to migration@EUI.eu during the embargo period (until 6 October 2019) ; This report compares two important corridor migrations to Belgium in order to better understand the variation in several dimensions of Turkish and Moroccan immigrants’ integration – in particular, labour market, education and citizenship. It is based on an original methodology combining three different data sources (an analysis of the legal and political frameworks, a quantitative analysis, and a survey). It aims to test the INTERACT project’s main hypothesis which conceives of integration as a three-way process. This report provides insight on integration from the immigration country perspective but also from the countries of origin; it appraises the impact that Turkey and Morocco may have on the integration of their migrants in Belgium. The main findings are the following. Firstly, the countries of origin may have an impact on integration when emigration starts. Secondly, countries of origin may have a positive or negative impact on some integration dimensions (citizenship) but no obvious impact on others (education and labour market). In their efforts to maintain and develop links and to protect migrants’ rights abroad, countries of origin can thus facilitate integration, but indirectly. ; INTERACT is co-financed by the European University Institute and the European Union
