What is chain immigration?

Our current system is dominated by the family reunification program.

Family reunification is really a self-selection process where one immigrant selects the next, who need only be an extended family member. Thus the term “chain migration.” Essentially, the government has no selective function. It merely verifies kinship.

It is past time to abandon this non-selective element of the 19th century “come one, come all” policy designed to settle the West and develop its agrarian economy.
