This book investigates the complex intersection between international migration patterns and the sustainability of national welfare systems within the European context. Authors Andrew Geddes and Michael Bommes, both established scholars in migration studies and political sociology, challenge the prevailing narrative that immigration inherently threatens social security. They provide a rigorous framework that examines how European states navigate the tension between inclusive social policies and increasingly restrictive border management.

Experts in European policy and sociology recognize this work as a critical contribution to the discourse on social citizenship and border control. Readers frequently note the academic density of the prose, which makes it a foundational text for students and researchers focusing on the structural challenges of the modern welfare state.
