Immigration Act of 1924: National Origins Quotas and Asian Ban

The Immigration Act of 1924, also called the Johnson-Reed Act, was a federal law signed on May 26, 1924, that put the first permanent numerical caps on immigration to the United States.¹ It capped annual immigration at roughly 165,000 under its initial formula, down from about 350,000 under the temporary 1921 law, and steered those slots toward Northern and Western Europe.² The same law barred virtually all immigration from Asia, created the modern consular visa system, and led directly to the founding of the U.S. Border Patrol. Its framework governed American immigration policy for 41 years, until Congress repealed the quotas in 1965.

The Quotas and Why the 1890 Census Was Chosen

The 1924 Act replaced the temporary Emergency Quota Act of 1921. The 1921 law had capped immigration from each nationality at 3 percent of the foreign-born population of that nationality recorded in the 1910 census, permitting roughly 350,000 arrivals per year.² Restrictionists in Congress wanted tighter numbers and a different mix.

The 1924 law cut the percentage from 3 to 2 and, more consequentially, shifted the baseline from the 1910 census to the 1890 census.³ Each country received an annual quota equal to 2 percent of the number of people born in that country who were living in the United States according to the 1890 census, with a minimum of 100 slots per country.⁴ Reaching back to 1890 was the point. Southern and Eastern Europeans had arrived in large numbers after that date, so the older snapshot shrank quotas for Italy, Poland, and Russia while preserving generous allotments for Great Britain, Germany, and Scandinavia. The overall ceiling fell to roughly 165,000. Within each country’s quota, preference went to immediate family members of U.S. citizens and to agricultural workers.

The National Origins Formula That Followed

The 1890 baseline was written into the statute as a placeholder. The act instructed federal officials to develop a permanent “national origins” formula, under which each country’s annual quota would be proportional to its share of the total U.S. population in the 1920 census, with the overall ceiling lowered to 150,000.⁴

Setting the country-by-country proportions proved contentious, and Congress delayed the switch twice. The permanent national origins quotas finally took effect on July 1, 1929. The results looked much like the 1890-based system. Great Britain and Northern Ireland alone received nearly half of the available slots. This formula governed U.S. immigration from 1929 until 1965.

Who Was Exempt From the Quotas

The act carved out several categories of “non-quota immigrants” who could enter without counting against a country’s ceiling:⁴

Wives and unmarried children under 18 of U.S. citizens living in the United States.
Natives of Canada, Mexico, Cuba, Haiti, the Dominican Republic, the Canal Zone, or any independent country of Central or South America, along with their spouses and minor children.
Lawfully admitted immigrants returning from a temporary trip abroad.
Ministers and university professors who had held their positions for at least two years and were entering to continue that work.
Students at least 15 years old entering to attend an approved school or university.

The Western Hemisphere exemption was the most consequential of these. It survived because Southern Democrats and Western legislators relied on cheap labor from Mexico and resisted any cap that would limit it.² Immigration from Latin America continued largely unrestricted while most of the Eastern Hemisphere faced hard numerical limits.

The Ban on Asian Immigration

For one large region, the act went past quotas to outright exclusion. It provided that no “alien ineligible for citizenship” could be admitted. Naturalization law dating back to 1790 and 1870 limited citizenship to “free white persons” and people of African descent, and that limit did the exclusionary work.²

Two recent Supreme Court decisions had drawn the line clearly. In Ozawa v. United States (1922), the Court ruled that a Japanese immigrant could not naturalize because he was “clearly not Caucasian.”⁵ In United States v. Bhagat Singh Thind (1923), the Court held that a South Asian man was not “white” under the common understanding of the word.⁶ Together, those rulings placed people from nearly every Asian country outside the naturalization statute and, under the 1924 Act, outside the country.

The Chinese Exclusion Act of 1882 had already blocked most Chinese workers. Japanese immigration had been managed since 1907 through the informal Gentlemen’s Agreement, under which Japan voluntarily limited emigration in exchange for no explicit statutory ban. The 1924 Act ended that arrangement, and the Japanese government protested formally.³²

The New Consular Visa Requirement

Before 1924, screening happened when a ship docked at an American port such as Ellis Island. The act reversed that sequence. Prospective immigrants now had to apply for a visa at a U.S. consulate in their home country before boarding. Each visa specified the applicant’s nationality, whether they fell under a quota or non-quota category, and an expiration date.⁴

Consular officers verified documentation and confirmed that quota slots were still available for the applicant’s nationality before issuing a visa. The fee was $9.⁴ Anyone who arrived at a U.S. port without the correct visa was rejected and typically sent back on the same vessel. This is the origin of the modern visa system, which continues in evolved form today.

Creation of the Border Patrol

Two days after President Calvin Coolidge signed the Immigration Act, Congress established the U.S. Border Patrol on May 28, 1924, through the Labor Appropriation Act.⁷ The new agency sat within the Immigration Bureau in the Department of Labor and was assigned to patrol the land borders with Mexico and Canada. With strict quotas now limiting legal entry, Congress expected that people would try to cross overland without documents, and the Border Patrol shifted federal enforcement from seaport inspection to active patrol of thousands of miles of territory.

How the Quotas Trapped Jewish Refugees in the 1930s

The quota framework produced its most severe consequences after 1933, when hundreds of thousands of Jewish Europeans tried to flee the Nazi regime. Germany’s annual quota was 25,957, later raised to 27,370 after Germany absorbed Austria, and even those slots were not always filled because of bureaucratic obstacles.⁸

Quotas were a ceiling, not a target, and unused slots did not carry over. Applicants were counted by country of birth, not current residence, so a Polish-born Jew living in Germany applied under Poland’s small quota rather than Germany’s larger one. By June 1939, the waiting list for the German quota alone had reached 309,782 people. An applicant from Hungary at that time faced a wait of nearly forty years.⁸ Congress did not adjust the quotas for the refugee crisis, and the 1924 framework remained the only legal path for entry through the years when escape from Europe was a matter of survival.

Repeal in 1965 and What Remained

The national origins quota system lasted 41 years. In 1965, Congress passed the Immigration and Nationality Act Amendments, known as the Hart-Celler Act, which abolished the national origins formula and replaced it with a system based on family reunification and employment skills.⁹

Several pieces of the 1924 architecture outlasted the quotas. The consular visa process still anchors U.S. immigration screening. The Border Patrol still enforces the land borders. And the principle that Congress sets numerical limits on who may enter, and from where, has remained a fixture of federal immigration law since the day the act was signed.
