Answer:
Increasingly, U.S. policy sought to limit the number of immigrants who were not white, Anglo-Saxon, and Protestant.
Explanation:
In the 19th and 20th century American policies were concern about immigration. America became one of the places where people immigrated to escape from poverty, persecution, political pressure, etc. With the increasing population in the 19th and 20th century, the U.S. implemented policies that limited the number of immigrants who were not white like Asians.
The immigration act of 1924 restricted the number of immigrants coming into the United States. This act establishes a national origin quota system that eliminated Asians from entering America.
