Explanation:

In the decade of 1920's, the restrictions on immigration increased. The government of the United States enacted the Immigration Act in the year 1924 to put restrictions on immigration. This act was the most severe of all the acts made to control immigration because it limited the overall number of immigrants and introduced quotas based on the nationality of immigrants.

The introduction of this act resulted in a sharp reduction in the number of immigrants coming from Eastern Europe and Africa and it completely restricted the immigration of Asians except for Japan and the Philippines. The government of the United States passed these immigration laws because many native groups opposed the continued migration in America.
