Polish Immigrant Organizations in Germany examines the situation of Polish immigrant organizations in Germany. Based on in-depth, mixed-method research consisting of surveys, case studies, and interviews with immigrants, representatives of institutions involved in the implementation of integration strategy and those responsible for Polish diaspora policy, it develops the notion of the transnational opportunity structure, which analyses the major factors shaping the situation of immigrant organizations.With attention to the characteristics of the migration process and the immigrant community, the country of residence, the country of origin, and bilateral relations between the two countries—which are in turn moderated by both global factors and micro factors—this book offers a multi-faceted analysis of diverse processes of developing diaspora groups and their organizations. It will therefore appeal to scholars of sociology, political science, security studies, and public policy with interests in migration and Diaspora studies, as well as intra-European mobility.
