International migration is a functional component of modern societies, both wealthy and poor. In a way, one can see that migration solves the unequal distribution of people and opportunities. Despite the political pressure to control immigration, almost all changes in politics have broadened the scope of legal immigration to allow for settlement by refugees, farm workers (in case of urbanrural migrations), “illegal” immigrants with long-term residence in the country, and workers in great demand to move around freely. Our main research objective is to demonstrate, using the available data as well as the analysis of the metadata and the research literature, that migration, especially labour migration, has a narrow connection with the issues of national security. Large outflows and inflows of people might bring about security threats linked to organized crime, terrorism and the spread of radical ideas. Moreover, migration is responsible for the brain drain of young and well-educated people who are searching for higher wages and better opportunities abroad depriving their own home country of valuable human capital. Our paper analyses the phenomenon of international migration perceived from the angle of migration culture that goes hand in hand with recent globalization trends all around the world. We come to a solid conclusion that migration policy should be treated as an important element in establishing well-ballanced national security policy in the globalized world. It might be of a particular interest for the migration scholars, labour market economists and stakeholders and policy-makers dealing with the issues of national security, public and migration policies, as well as sustainable economic development.
