The purpose of this research is to examine whether Serbia’s accession to the European Union represents migrational threat to EU member countries. Therefore, we have conducted a research on migration potential on representative sample in Serbia in order to gain insight into the scope, structure but also determinants of migration potential. The research also provides important information on characteristics of potential migrants, reasons for migration and destination countries. The data are important for the creation of migration policies of the country and the assessment of demographic, economic and social detriments, but also the assessment of their potential for return through connections of migrants with the country of origin and possible return to the homeland. The research is also important since it is one of rare ones related to migration potential of Serbia. It contains the following chapters: research methodology, sample, migration potential, potential migrants profile, motives and obstacles to migration, destination countries, conclusions and recommendations.
