Key theories and studies of migration systems in modern domestic and foreign science are considered. In this context, the definition and con-tent of the concept of «migration corridor» as a form of sustainable migration links between sending and receiving countries is also being developed. The Eurasian migration corridor as a part of the Eurasian migration subsystem is theoretically justified and statistically described. It is also noted that the Slavic and Caucasian migration corridors have been formed in the post-Soviet space. It is noted that the Euro-Asian migration corridor was formed on the basis of stable migration flows between the Central Asian countries and the Russian Federation, which are characterized by large-scale flows of labor and educa-tional migrants in favor of Russia and significant amounts of money transfers in favor of sending coun-tries. The migration flows that make up the Euro-Asian migration corridor are dominated by temporary forms of migration, primarily labor and educational. The key migration channels of the Euro-Asian mi-gration corridor are assessed in terms of participation of citizens of five Central Asian countries — Ka-zakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. The article highlights the peculiarities of the transformation of temporary forms of migration into permanent residence in Russia and the partic-ipation of citizens of the region in them. The positive and negative aspects of labor migration from Cen-tral Asia to Russia for sending countries in the region are highlighted.
