The freedom of movement and residence for persons is one of the cornerstones of the European Union. Therefore the regulation of the mobility of economically active citizens of EU Member States and their family members has been one of the core activities of the EU policy- and law-makers which has led to the introduction of EU citizenship with the Maastricht Treaty in 1992. However, freedom of movement is not an uncontested principle – as recent events have clearly shown. Added to this is a growing concern regarding migratory movements of Third Country Nationals to Member States of the European Union: either as labor migrants, in the form of family reunification, or as applicants for international protection. The EU and its Member States currently face the challenge of having to find a way forward within the legal and political frameworks existing in Europe. This year’s summer school aims at adressing this challenge from different perspectives.
