Answer:
As a restriction on new immigrants, the government established the Immigration Act of 1924.
Step-by-step explanation:
The Immigration Act of 1924 was an act of intolerance and prejudice towards some immigrants from some parts of the world, mainly Asian and Europeans from southern and eastern Europe. This law required the American government to adopt a quota system for each country, so that each country had a limit on the number of immigrants who could enter and stay in the USA. This was a completely decriminalization law that was maintained until 1965.
