The Johnson-Reed Immigration Act made it harder for some Europeans to immigrate to the United States, and easier for other nationalities.

The Immigration Act of 1924, also known as the Johnson-Reed Act, was a federal law passed on May 16, 1924 in the United States of America to limit immigration. It banned entry to the entire Chinese population and extended restrictions to other Asian immigrant groups, and to a lesser extent, to people from Eastern and Southern Europe; but it did not apply to persons from the American continent.
