During the past decade the European Union has developed the foundations of a common migration policy by harmonising national immigration and asylum laws and introducing new instruments. Despite some remarkable achievements European policy-makers have struggled to build a conceptual basis for migration policy. The Stockholm Program on the future of the Area of Freedom, Security and Justice underlines the need for continued critical reflection about the conceptual foundations and legal challenges of European migration law. This collection of essays by young and promising European lawyers from different national and academic backgrounds supports an interdisciplinary approach to the analysis of European migration law, reflecting the political, economic and sociological context of legal rules governing the international movement of people. Since European migration law is a relatively new area of European law-making, young scholars are in a particularly good position to enhance our understanding of recent developments in and future challenges of the construction of European migration law.
