Theoretical approaches in the study of international migration. Migration networks

A constant theme in the research of international migration, the phrase "migration network" defines a system of relations built in a certain region, among migrants and former migrants, migrants and non-migrants or potential migrants, both in the areas of origin or in the destination ones, based on various types of relationships, being relatives, friends, or sharing a common history. This paper aims to introduce several paradigms that form the foundation of the migration network theory in the study of international migration. As further presented, some authors claim that, due to the existence of said social networks, the migrants flows are being directed towards certain areas and fields of work, by creating a connection between the labor market in the country of origin and that of destination. The perspective of social networks in the approach of migration can be summarized by the following: the networks connect migrants in time and space. Once the migration flows are being initiated, they come to sustain themselves, reflecting the institutionalization of information networks, help and obligations that develop among migrants in the host society, and the friends and relatives in the emigration area.
