End Chain Migration
Chain Migration refers to the endless chains of foreign nationals who are allowed to immigrate to the United States because citizens and lawful permanent residents are allowed to sponsor their non-nuclear family members.
It is the primary mechanism that has caused legal immigration in the U.S. to quadruple from about 250,000 per year in the 1950s and 1960s to more than 1 million annually since 1990. As such, it is one of the chief culprits in America's current record-breaking population boom and all the attendant sprawl, congestion, and school overcrowding that damage Americans’ quality of life.
