Answer:
The major change in the U.S immigration policy that was reflected in the United States Immigration Act of 1965 was the abolition of the quota system of immigration based on national origin which was what was invoke prior to the enactment of the 1965 Immigration Act.
Step-by-step explanation:
The United States Immigration Act of 1965 brought with it innovation in the U.S immigration policy. Prior to the enactment of the Act, immigration into the U.S was based on a quota system which was bench-marked on national origin. The quota system was viewed as discriminatory, thus some civil rights movements clamored against it and called for a reform of the United States Immigration policy. This led to a heated debate in the United States congress, and consequently, the enactment of the 1965 Immigration Act which abolished the quota system and enthroned a more liberal immigration policy which was more accommodating of immigrants. The 1965 Immigration Act focused more on absorbing immigrants with skilled labor and refugees from war torn countries into the United States as well as reuniting immigrant families.
