Asians!

Surveys had shown that the Native American population were suffering economically from the increase in immigration from Asia and North/South Europe. Therefore the act was implemented to solve this problem.

The new laws in the 1920s significantly changed US immigration policy by introducing quotas and restrictions. The Immigration Act of 1921 established the first-ever numerical quotas for immigrants based on their nationality. The Immigration Act of 1924, also known as the Johnson-Reed Act, further restricted immigration by setting even stricter quotas based on the national origins of immigrants and completely banned immigration from certain regions, particularly Asia. These laws aimed to limit immigration and preserve the ethnic composition of the United States.

The law aimed to restrict Southern and Eastern European immigration while favoring immigration from Western European countries. This legislation marked a shift towards more restrictive immigration policies in the U.S.
