This open access short reader provides a compelling introduction to research on migrant transnationalism. The short reader focuses on the significant area of remittances (in financial terms). However, attention is also paid to political, social, cultural and religious transfers and exchanges underscoring the salience of the wide range of ties that are maintained across borders. Increasingly  such ties are sustained through virtual and technology facilitated modes of interaction. Drawing on  established and recent empirical research from across the globe, in dialogue with scholars of migrant transnationalism, the book offers an overview of approaches, conceptual tools, thematic areas, and methods of investigation.Thus, this short reader sheds light on the fundamentals of existing knowledge on migrant transnationalism: What are the key questions in migrant transnationalism research today? How does a transnational perspective deepen our understanding of migration, (social) mobility, diversity, inclusion and development? As a source for researchers, students and policy makers, this short reader is essential reading which shows why looking at the world through a transnational lens adds value, for anyone interested in migration and social change.
