After many years of dealing with the emigration of the population, Croatia has recently encountered increased immigration on its territory. The structure of the immigrant population, which is predominantly an immigrant labor force, has recently been marked by increasing multiculturalism and it is no longer only about the population of neighboring countries, which requires a new adaptation. In this paper, we deal with the issue of integration of the new immigrant population, which is defined as a two-way process. There is a demand for adaptation of immigrants who come to the territory of the Republic of Croatia, as well as those on the side of the local population. Different dimensions of integration include legal and political participation, characteristics of the labor market, enabling and creating various social rights for immigrants, and cultural acceptance and attitudes of society towards immigrants. It is crucial to observe each of the dimensions in the Croatian social context and recognize certain obstacles and advantages for the integration of immigrants.
