In the conditions of an unsurmounted geo-economic crisis the factor of international migration remains the main challenge to national and international security. National security, to a great extent, is determined by the country's political stability, the social environment, socio-cultural relations and economic potential. These factors, in turn, emerge labour migration processes, which can become direct threats to the security of the countries participating in these international flows. Based on the performed analysis, we can conclude that the relationship between security and migration is evident and very complex, since migration can be an important factor of national security, but at the same time, migration is a result of the security environment. In our view, international labour migration, in the context of national security, is one of the most current issues of state policy in most countries, the causes being different, starting with excess of migrants to the need of solving the demographic imbalance through migration flows. Security is possible by effective policies, including migration policy, their implementation being based on social consolidation, social support of government goals and actions, security can not exist in isolation, being interdependent with the life of the individual, society and state.
