Abstract. The migration challenges occurring in the world require joint efforts from the state to control and regulate within the framework of various integrations. The article examines the features of the legal regulation of labor migration flows of three integration associations. The associations are EU, NAFTA (USMCA), EAEU. The subject of the study is the internal and external migration policies of the associations. Special attention is paid to study international, integration and national migration regulations. They relate to the goals of associations and the needs of the labor markets of the members. In conclusion the legal acts of integration associations regulate labor migration and have a number of inconsistencies. Migration policy often is carried out by individual countries based only on their own national interests.

Key words: labor migration; migration policy; migration flows; integration associations; EU; NAFTA; USMCA; EAEU.
