Once the broader opportunities are set, the familiar story about evolving migration dynamics goes like this: as migration flows develop, potential migrants who have stayed at home can move in increasing numbers. For this to occur, migrant networks need to form: With the existence of migration networks and the support they carry, it becomes easier to travel abroad, to find work and housing, to get adjusted to new types of work, to change jobs, to find child care, to keep in touch with the country of origin, and to consummate communal and spiritual needs. Information then flows through personal contacts, such as recurrent, transilient, and return migrants, and within immigrant clusters, such as manifold Landsmannschaften. In short, migrant networks, reduce the economic and psychological risks and costs associated with international long-distance migration.
