Notes: Because of a typical 9-year lag between permanent residence and naturalization, which is a precondition for sponsoring numerically exempt immediate relatives and some family preference relatives, the 3S, 3C, 3P, and 4F cohorts are advanced by nine years; multipliers reflect that the 1981–1985 initiating cohort corresponds to 1990–1994 3S, 3C, 3P, and 4F family admissions, etc.
