Migration refers to the movement of people from place to place for life or work. Along with other social controversies, international migration is becoming an increasingly global phenomenon that is researched by numerous scientific disciplines, but systematic research dealing with the connection of social networks with migration and integration activity is rare. This research starts from/begins with the theory of migrant networks and social capital in order to investigate in more detail the main motives of migration, the integration and transmigration aspects of migrants' activities and the plan of (non)return to the country of origin. This is a relatively unexplored area as far as Croatian migration history is concerned, although it is inevitable that "traditional" emigration to Germany resulted in numerous migrant networks. The research was conducted using a semi-structured interview method on a sample of 10 young migrants from Zagreb and Zagreb County who are working in Germany. The research results show that cross-border migration represents a need caused by deep-rooted political, economic and social problems that dominate Croatian society. Croats traditionally emigrated to Germany, which resulted in a branched migrant network, which in modern times promotes/improves new migrant and integration flows. An important characteristic of contemporary migrations of the Croatian population refers to the transnational activities by which they connect the country of immigration and the country of origin, while the return to the homeland is only possible if financial stability is ensured and political-labor relations are arranged, because they represent the main push factors.
