This book brings together scholars from various disciplines to explore current issues and trends in the rethinking of migration and citizenship from the perspective of three major immigrant democracies – Australia, Canada, and the　United States. These countries share a history of pronounced immigration and emigration, extensive experience with diasporic and mobile communities, and with integrating culturally diverse populations. They also share an approach to automatic citizenship based on the principle of jus soli (as opposed to the traditionally common jus sanguinis of continental Europe), and a comparatively open attitude towards naturalization. Some of these characteristics are now under pressure due to the "restrictive turn" in citizenship and migration worldwide.

This volume explores the significance of political structures, political agents and political culture in shaping processes of inclusion and exclusion in these diverse societies. This book was originally published as a special issue of Citizenship Studies.
