Answer:
Abolished the old immigration quotas.
Explanation:
Since the Immigration Act of 1924, immigration was based on a national-origins quota system, which provided immigration visas to 2% of the total number of people of each nationality in the United States, based on the 1890 national census.
The Immigration Act of 1965 abolished those immigration quotas and established a visa system for reuniting immigrant families and attracting skilled labor people to the United States.
