Millions of children are on the move worldwide. They are fleeing conflicts and wars, they move with or without their parents to attain a better future. This is not a new phenomenon, but its current scale is unprecedented. UN reports suggest that there are currently almost 50 million children who have been uprooted, constituting half of the global refugee population. Migrant and refugee children often find themselves in particularly vulnerable positions, despite the comprehensive human rights protections accorded to them in regional and international legal instruments, including the United Nations Convention on the Rights of the Child adopted 30 years ago. Safeguarding Children’s Rights in Immigration Law is a reflection of the growing concern for children and children’s rights in immigration in academia and practice. It also analyses the diversity of issues related to immigration and children, such as family reunification, detention, participation, human tracking and the rights of siblings in the context of migration, as well as the significance of regional legal systems and infrastructures for the protection of children on the move.The topics explored in this book emphasise its international scope and importance, making it of interest to academics, practitioners, the wider legal profession and law students everywhere.
