The article deals with political discourse on the problems of migration regulation and integration of immigrants from different cultures in the EU countries with focus on dynamics of his discourse in the aftermath of the migration crisis peak in 2015. The research shows that the aggravation of migration crisis in the EU not only stimulated and actualized political discourse on the regulation of migration, but also revealed the presence of different, sometimes oppositional approaches in this field. Visible politicization of the discourse on migration problems in the EU countries, which is evident in the European mass media, has a negative impact on the social cohesion of society, triggering political polarization, and contributes to growing influence of populist parties and movements. This puts the supranational structures of the EU and the political leadership of individual European countries before the need to develop an adequate and effective response to the challenges of a dramatically increased ethno-social and ethno-cultural heterogeneity. The analysis shows that attempts to replace (or substitute) the problem of integration of migrants from the countries of the Middle East and Africa with the refugee problem, and the migration crisis being renamed the “refugee crisis”, are only partially effective and in general do not contribute to overcoming political polarization. The calls in the political discourse for control over migration, as well as over the external and internal borders of the EU countries have a greater effect and affect the policies of a number of EU member states.
