Immigration Act of 1924
Immigration Act of 1924 is also known as the Johnson-Reed Act. Similar to the Immigration Act of 1921, this act also employed quotas in order to exclude immigrants from entering the country. However, the quotas was lowered to 2% of the total number of the people from that country who were already living in the U.S. Unlike the Immigration Act of 1921, this act hurt the southern and eastern Europeans or the "New Immigrants." Thus, this one is more effective than the previous act.

Gas and Breaks For Immigration in 1920s
Nativism was a concept that became more popular during the 1920s. For example, Ku Klux Klan increased its members drastically during this period of time. Also, for the trial of Sacco and Vanzetti, they did not receive a fair trial because of the inconclusive evidence, which shows that the thrive of nativism caused people to care more about the safety of their country than justice.
Due to nativism, immigrants were rejected from entering the United States, which is the "break" in 1920s. The immigration in America during this period of time was going backwards. For example, in 1882, the Chinese Exclusion Act was passed to prevent Chinese people from taking away jobs in the country. In the 1920s, the Americans were preventing immigrants to get rid of foreign radicals and protect the safety of the country.
Immigrants were restricted from entering the country during 1920s due to the growing nativism among the Americans. Sacco and Vanzetti case made Americans worried about foreign radicals. Thus, the Immigration Act of 1921, which allowed 3% of the total number of foreign-born persons from their original country, was passed to limit the number of immigrants. Later, the Immigration Act of 1924, which only allowed 2% of the total number of the people from that country who were already living in the U.S, was signed by President Coolidge to further restrict immigrants. The "gas" of the immigration in 1920s was the thrive of nativism, and the "break" was the number of immigrants allowed to come to America.
