An important adaptation and integration tool of the state migration policy is teaching migrants the language of the recipient country. Insufficient language knowledge and skills of migrants or their insufficient motivation to learn the language for quick adaptation and integration into the society of the recipient country is one of the main problems facing the integration policy of various states. Teaching migrants of various ages and gender at different educational levels to the language of the recipient country increases the efficiency of adaptation and integration of migrants, and also increases the level of tolerance of the major population of the country. The problem of the language training of foreign citizens in the system of state migration policy is discussed using the example of the Russian Federation and several European countries. The article analyses some features of the post-crisis migration period in the light of the current trend towards increased migration from countries of origin that do not have close historical, linguistic and cultural ties with the recipient country, as well as the reasons for the differences in language integration policy, the motivation of migrants to learn the language and existing approaches to the language integration of migrants. The existing practice of preliminary language testing of future migrants is discussed.
