This book examines the role and impact of EU, international human rights and refugee law on national laws and policies for integration and argues for a broad understanding of the relationship between integration and the law. It analyses the legal foundations of integration at the international and regional levels and examines the interaction of national, EU and international legal spheres, highlighting the significance of these dimensions of the relationship between integration and the law. The book draws together these central themes to enhance our understanding of the connections between integration and the law. It also makes specific recommendations for the development of holistic, human-rights based approaches to integration in EU Member States. The book will be of value to academics and researchers working in the areas of immigration, and refugee law, as well as those interested in cultural diversity both from a legal and sociological perspective.
