This reference book sheds lights on the way countries are changing in an effort to control the transnational movements and practices of migrants.

Dual citizenship agreements, outsourcing of border security, the proliferation of government departments dealing with diasporas… Nation-states are developing a growing number of tools for extending their reach beyond their borders. How are policies targeting the flow of migrants transforming governments? This work updates debates on transnationalism that have animated migrant studies for over thirty years. Thomas Lacroix explores the close connections between the "transnational state"—that is, the sum total of a nation's policies and departments aimed at regulating transnational migrations—and the "transnational society," or the tangle of social institutions enabling ties, practices, and relationships to be maintained across borders.
