Answer:
The law abolished the National Origins Formula, which had been the basis of U.S. immigration policy since the 1920s.
Explanation:
The National Origins Formula, the cornerstone of American immigration law since the 1920s, was eliminated by the statute, which is the Immigration and Nationality Act of 1965.
The act ended de facto discrimination in American immigration policy against Southern and Eastern Europeans, Asians, and other non-Western and Northern European ethnic groups.

Priority is given to family members and children of citizens and legal permanent residents of the United States, professionals and other people with specialized talents, and refugees under a seven-category preference system established by the Immigration and Nationality Act of 1965.
According to the definition of de facto discrimination, segregation and other unfair practices take place without being sanctioned by the law. De facto discrimination occurs when there are widespread, legally unjustified behaviors that are followed by the majority of individuals.
