This book is concerned with the analysis of the pre-accession and post-accession process in the field of free movement of persons in the EU. It examines the extent to which nationals of states covered by Europe Agreements and Stabilisation and Association Agreements derive rights related to free movement and non-discrimination under three categories of economic movement - as workers, as self-employed persons and as service providers. The text discusses a number of controversial issues related to the topic of movement, such as access to the Member States' labour market, family reunification rights and transitional arrangements in the post-accession period. It reveals that the transformation of the status of economic migrants is not finalised immediately upon accession and the sensitivities surrounding free movement of persons from the new Member States remain much longer.
