END CHAIN MIGRATION
Chain Migration refers to the endless and often-snowballing chains of foreign nationals who are allowed to immigrate because the law allows citizens and lawful permanent residents to bring in their extended, non-nuclear family members. It is the primary mechanism that has caused legal immigration in this country to quadruple from about 250,000 per year in the 1950s and 1960s to more than one million a year since 1990.
