In this article, the authors analyzed the process of formation and development of the migration
theory, from the end of the XIX century to the beginning of the XXI century through the method of
documentary research. As a result, the countries of origin reap the benefits of intellectual migration
in the event of the return of their highly qualified personnel to their homeland. In conclusion, the
labor market and the education system play the role of connecting elements between Diasporas and
the local population, through which representatives of ethnic groups are built-in into the existing
system of relations.
