The 1990 Immigration Act (IMMACT 90), which became Public Law 101-649 on Nov. 29, 1990, dictates:
"IN GENERAL- Exclusive of aliens described in subsection (b), aliens born in a foreign state or dependent area who may be issued immigrant visas or who may otherwise acquire the status of an alien lawfully admitted to the United States for permanent residence are limited to--
(1) family-sponsored immigrants described in section 203(a) (or who are admitted under section 211(a) on the basis of a prior issuance of a visa to their accompanying parent under section 203(a)) in a number not to exceed in any fiscal year the number specified in subsection (c) for that year, and not to exceed in any of the first 3 quarters of any fiscal year 27 percent of the worldwide level under such subsection for all of such fiscal year;
(2) employment-based immigrants described in section 203(b) (or who are admitted under section 211(a) on the basis of a prior issuance of a visa to their accompanying parent under section 203(b)), in a number not to exceed in any fiscal year the number specified in subsection (d) for that year, and not to exceed in any of the first 3 quarters of any fiscal year 27 percent of the worldwide level under such subsection for all of such fiscal year; and
(3) for fiscal years beginning with fiscal year 1995, diversity immigrants described in section 203(c) (or who are admitted under section 211(a) on the basis of a prior issuance of a visa to their accompanying parent under section 203(c)) in a number not to exceed in any fiscal year the number specified in subsection (e) for that year, and not to exceed in any of the first 3 quarters of any fiscal year 27 percent of the worldwide level under such subsection for all of such fiscal year."
The U.S. Citizenship and Immigration Services (USCIS), in a section entitled "Immigration Act of 1990" on its website (accessed May 7, 2007), explained:
"The Immigration Act of 1990, , increased the limits on legal immigration to the United States, revised all grounds for exclusion and deportation, authorized temporary protected status to aliens of designated countries, revised and established new nonimmigrant admission categories, revised and extended the Visa Waiver Pilot Program, and revised naturalization authority and requirements."
The Center for Immigration Studies, in a Sep. 1995 essay entitled "Three Decades of Mass Immigration, The Legacy of the 1965 Immigration Act" on its website, offered the following:
"1990 Immigration Act (IMMACT) — Modified and expanded the 1965 act; it significantly increased the total level of immigration to 700,000, increasing available visas 40 percent. The act retained family reunification as the major entry path, while more than doubling employment-related immigration. The law also provided for the admission of immigrants from 'underrepresented' countries to increase the diversity of the immigrant flow."
