Abstract: This article explores the questions of legal regulation of work migration of the citizens of third countries into the EU. Migration on a globalized world is polyoptional and diverse. Covering various social groups, we well as multiple areas of public livelihood, it represents one of the most active driving forces contributing to growth and reallocation of labor resources in the EU, contributing in turn to its economic growth. The necessity to solve the issues pertaining to work migration is substantiated by the creation of the corresponding legal base on the international level and harmonization of the internal legislation of the EU member-states. The methodological base of this research includes general scientific methods (analysis and synthesis, dialectics, logical method), as well as special legal methods: historical-legal, comparative legal, formal legal analyses. The author concludes that the EU and its member-states need to continue reworking the domestic and European legislation in the area of labor and strengthening the integration in the labor market. The efforts should be coordinated towards creation of legislative base on the issues of trans-state exchange of workers from third countries. At the same time, optimization of the migration policy in Europe is not possible without solution of the issues related to socio-psychological, cultural and language adaptation of the migrants.
