The conditions for non-EU migrant workers to gain legal entry to Britain, France, and Germany are at the same time similar and quite different. To explain this variation this book compares the fine-grained legal categories for migrant workers in each country, and examines the interaction of economic, social, and cultural rationales in determining migrant legality. Rather than investigating the failure of borders to keep unauthorized migrants out, the author highlights the different policies of each country as “border-drawing” actions. Policymakers draw lines between different migrant groups, and between migrants and citizens, through considerations of both their economic utility and skills, but also their places of origin and prospects for social integration. Overall, migrant worker legality is arranged against the backdrop of the specific vision each country has of itself in an economically competitive, globalized world with rapidly changing welfare and citizenship models.
