and why, addressing regional disparities within Bulgaria. The text explores the impact of economic differences, educational background, and other factors that play into immigrants¿ motivations to move. The next part of the book examines different migratory movements and transnational practices between Switzerland, Bulgaria, and other destination countries for Bulgarian immigrants. It addresses larger socioeconomic shifts and resulting impacts at individual, household, community, and national levels. Finally, the book assesses all of these factors within the context of shifting immigration policies. This work draws on mixed-method empirical research conducted in both countries over a three- year period, analysed within four major frameworks: transnationalism and migrant networks, social inequality, regional disparities and development, and immigration policies. The results will be of interest for researchers working in a variety of social science fields, including anthropology, geography, sociology, social psychology, law, public policy, political science, international studies, demography and exploring issues related to migration and development, social and regional disparities, inequality, employment, social networks, social identity and others.
