Chain Migration and Assimilation
By Andrew R. Arthur on December 20, 2017
On December 15, 2017, the White House issued a release captioned "It's Time [t]o End Chain Migration". That release includes a package of graphs and slides that detail the effect of chain migration on immigration to the United States.
That package begins with an introductory paragraph that includes the following:
Chain Migration also undermines national security, by failing to establish merit-based criteria for evaluating entrants into the United States — instead, familial relations are all that is required to obtain a green card and, in turn, become a voting U.S. Citizen within a short period of time, with access to Federal welfare and government benefits.
