Impact of migration on the security situation is the attention of politicians, sociologists and other specialists, given the problems they cause, because in their view migration is a direct threat to the sovereignty and national security. To determine the interdependence between migration and security in the international system is necessary to analyze the extent to which migration has an impact on the countries of origin and countries where migrants are heading. The tragic events that occurred in recent decades (USA, Spain, London, Beslan, India, Syria, etc.) allow us to advance the hypothesis that there is a link between migration, terrorism and security.
