Unprecedented numbers of children are crossing international borders seeking safety. Framed around compelling case studies explaining why children are on the move in Africa, the Americas, Asia, Europe, the Middle East and Oceania, this book explores the jurisprudence and processes used by nations to adjudicate children’s protection claims. The book includes contributions from leading scholars in immigration, refugee law, children’s rights and human trafficking which critically examine the strengths and weaknesses of international and domestic laws with the aim of identifying best practice for migrant children.
