By the end of 1920, immigration levels approached prewar figures.
Ellis Island once again became a bustling hub for immigrants.
Discussions surrounding immigration in Congress were filled with anxiety and fear.
Influential groups including the American Legion and the American Federation of Labor voiced concerns about imminent immigration.
Fears were fueled by warnings of "hordes" of impoverished individuals fleeing the aftermath of war.
The reduction in maritime travel costs facilitated immigration.
Congressman Albert Johnson, a prominent restrictionist, advocated for an immediate two-year halt to immigration to avoid being overwhelmed by what he termed "undesirable aliens."
Johnson cited estimates from American consulates in Europe, notably a prediction of 100,000 to 350,000 Polish Jews wishing to emigrate to the U.S.
Concerns from consuls in Italy highlighted perceived threats from socialist ideas among the emigrants.
Johnson argued for total restrictions to prevent the entry of subversive individuals into the U.S.
Support for immigration restrictions became widespread in Congress, driven by nativism, job scarcity, and anti-Bolshevism.
In May 1921, Congress enacted an emergency measure limiting immigration to 355,000 annually.
This legislation set quotas for each European nation at 3% based on the number of that nationality’s foreign-born citizens in the U.S. in 1910.
Congress allocated fourteen months to develop a permanent immigration policy.
The period between the 1921 legislation and the Johnson-Reed Act saw intense debate over immigration policy design.
This act would solidify values regarding which immigrant sources were deemed acceptable and would reshape the social structure of the nation.
Many nativists viewed the 3% quotas established in 1921 as flawed, advocating for a new system based on the 1890 census.
They argued that the 1890 basis would drastically reduce immigration from southern and eastern European nations, limiting their contributions to only 15% of total immigration.
The discriminatory nature of the 1890 formula led critics to call for the most up-to-date figures from the 1920 census.
Using more recent census data was seen as a more equitable approach, but debate continued over the implications of such demographics on national identity and policy.
