This book provides a multi-disciplinary investigation of family reunification laws, policies and practices across the European Union. Family reunification - the possibility for family members to (re)unite in a country where one of them is residing - has been high on the political agenda. Building on original empirical research with families and practitioners as well as in-depth doctrinal analyses, the book explores the fragmentation of legal rules, the gaps between formal regulations and practices, and their consequences for families across borders. Different contributions in the volume point to the growing inequalities among and within applicant families, based on residence status, gender, location, citizenship and socio-economic resources, due to the family reunification regimes currently in place.The book enhances interdisciplinary dialogue by providing clear insights into the specific contribution of migration law, private international law and social scientific analyses to the study of family reunification. The book is aimed at researchers working on the topic of family reunification, as well as students of law and socio-legal studies and practitioners in the field of migration.
