International Migration Law provides a detailed and comprehensive overview of the international legal framework applicable to the movement of persons.The role of international law in this field is complex, and often ambiguous: there is no single source for the international law governing migration. The current framework is scattered throughout a wide array of rules belonging to numerous branches of international law, including refugee law, human rights law, humanitarian law, labour law, trade law, maritime and air law, criminal law, and consular and diplomatic law. This textbook therefore cuts through this complexity by clearly demonstrating what the current international law is, and assessing how it operates.

The book offers a unique and comprehensive overview of this growing field of international law. It brings together and critically analyses the disparate conventional, customary, and soft law on a broad variety of issues, such as undocumented migration, nationality, trafficking, family reunification, refugee protection, non-discrimination, regional free movement schemes, and trade and development. It also offers a particular focus on important groups of migrants, namely migrant workers, students, and refugees. It maps the current status of the law governing their movement, providing a thorough critical analysis of the various stands of international law which apply to them, suggesting how the law may continue to develop in the future. This book provides the perfect introduction to all aspects of migration and international law.
