RESEARCH REPORTS EU Accession and Migration: Evidence for Bulgarian Migration to Germany

Bulgaria’s European Union accession in 2007 turned the country’s citizens from third-country na-tionals with restricted mobility rights into EU citizens with rights to free movement within the EU. Economic rights were restricted for seven years by transitional periods in the free movement of work-ers. This article explores changes in the Bulgarian migration pattern to Germany after 2007 in the specific context of free movement with restricted freedom to work, and analyses the extent to which those changes can be related to that particular regime. Starting from this point, Bulgarian migration patterns to Germany are overviewed and a periodisation of migration since the World War II is sug-gested. Changes in the dynamics, forms and composition of migration after EU accession in 2007 are analysed, based on administrative data and a small-scale survey among Bulgarian migrants in Ham-burg. Both the administrative data and the survey results provide empirical grounding for a plausible relation between EU accession and migration patterns. The scale of migration has increased and more temporary migration has taken place. However, the rise of migration can be attributed not only to new migration from Bulgaria but also, to a large extent, to a redirection of migration flows from other destination countries and the legalisation of irregular migrants. Circular migration has lost to a great extent relevance which could be plausibly explained by changed migration strategies under a regime of free movement. Despite transitional periods in the free movement of workers, labour mi-gration has become a predominant form of mobility. Transitional periods did not prevent migrants from moving to Germany but, given the reduced labour market opportunities, may have hampered their successful labour market integration
