The article is intended to analyze the legal aspects of the impact of educational migration on the national security of Ukraine. The legal basis of educational migration is considered, in particular, the consolidation of Ukraine's participation as a full participant in the European educational space in the regulatory framework and its impact on Ukraine's national security. The positive and negative consequences of educational migration and their impact on the national security of the country are analyzed. Comprehensive measures, including legal ones, in the field of education and migration policy of Ukraine have been identified. Academic mobility and cross-border education are identified as the main institutional forms of educational migration. Today, the national security of Ukraine requires the protection of the public interests of all segments of the population, including young students, which ensures the sustainable development of the country and society. The vast majority of migrants are young people - the most active part of the population, prone to self-development and adaptation in a multicultural environment. Ensuring constitutional human rights and freedoms, including their right to education, are objects of national security. It is proved that international integration and integration of the national higher education system into the European educational space is one of the main principles of state policy in education. Accordingly, there are academic mobility programs in the field of international cooperation. Migration policy is one of the priority areas of the country's development. Migration is a complex process that includes, in addition to legal, economic, socio-psychological, political and cultural interrelationships. The issue of modern migration processes and national security is always promising in terms of further research, especially given that the analysis of the migration situation in Ukraine shows that they are developing much more dynamically than the process of legal regulation in this area. In fact, it is about the complexity of effective legal regulation of migration processes in the country.
