Nonpreference visas were available to qualified applicants not entitled to a visa under the preferences until the category was eliminated by the Immigration Act of 1990. Nonpreference visas for persons not entitled to the other preferences had not been available since September 1978 because of high demand in the preference categories. An additional 5,000 nonpreference visas were available in each of fiscal years 1987 and 1988 under a provision of the Immigration Reform and Control Act of 1986. This program was extended into 1989, 1990, and 1991 with 15,000 visas issued each year. Aliens born in countries from which immigration was adversely affected by the Immigration and Nationality Act Amendments of 1965 (Public Law 89-236) were eligible for the special nonpreference visas.
