Chain migration
Chain migration is the social process by which immigrants from a particular area follow others from that area to a particular destination. The destination may be in another country or in a new location within the same country.
John S. MacDonald and Leatrice D. MacDonald define chain migration as "movement in which prospective migrants learn of opportunities, are provided with transportation, and have initial accommodation and employment arranged by means of primary social relationships with previous migrants". Dara Lind of Vox describes it as a process in which "[p]eople are more likely to move to where people they know live, and each new immigrant makes people they know more likely to move there in turn."
During the debate on immigration policy following Donald Trump's rescission of the Deferred Action for Childhood Arrivals program, the use of the term "chain migration" became contentious.
