Preference System (prior to fiscal year 1992)

The six categories among which 270,000 immigrant visa numbers were distributed each year during the period 1981-91. This preference system was amended by the Immigration Act of 1990, effective fiscal year 1992. (see Preference System - Immigration Act of 1990). The six categories were: 1) unmarried sons and daughters (over 21 years of age) of U.S. citizens (20 percent); 2) spouses and unmarried sons and daughters of aliens lawfully admitted for permanent residence (26 percent); 3) members of the professions or persons of exceptional ability in the sciences and arts (10 percent); 4) married sons and daughters of U.S. citizens (10 percent); 5) brothers and sisters of U.S. citizens over 21 years of age (24 percent); and 6) needed skilled or unskilled workers (10 percent). A nonpreference category, historically open to immigrants not entitled to a visa number under one of the six preferences just listed, had no numbers available beginning in September 1978.
