Abstract

The gradual development of European Union (EU) immigration and asylum law has been characterized by two related, ongoing tensions: the conflict between EU competence in this field and national sovereignty, and the friction between immigration control and the protection of human rights. The EU's approach to resolving the two key tensions in this area are assessed by examining the four key subjects addressed by immigration law: visas and border controls, irregular migration, legal migration, and asylum. The European Union has been more active in the fields of visas and border controls than in any other area of immigration and asylum law owing to the early development of a legal framework, originally in the form of the Schengen Convention. As for irregular migration, the European Union's initial piecemeal approach has been supplemented by the adoption of the fairly comprehensive Returns Directive.
