This document discusses the concept of immigrant transnationalism, which refers to immigrants regularly engaging in economic, political, and socio-cultural activities that span national borders as part of their daily lives. Advances in transportation and communication have enabled more durable and frequent participation by immigrants in their home countries. The document examines drivers of transnationalism like globalization and how contexts of exit and integration shape transnational activities. It finds that transnationalism takes many forms like business investments, remittances, and cultural exchanges. Transnationalism challenges theories that assume immigrants fully integrate into host societies and severs ties with home countries.
