The Johnson-Reed Act of 1924 was a federal immigration law that imposed the first permanent numerical caps on immigration to the United States, built a national-origins quota system that heavily favored Northern and Western Europe, and effectively barred all immigration from Asia. It set annual country quotas at 2 percent of each nationality’s foreign-born population recorded in the 1890 census, required prospective immigrants to obtain a visa from a U.S. consulate before sailing, and shaped who could enter the country for the next four decades until Congress repealed the quota system in 1965.
The National Origins Quota Formula
Section 11 of the Act set each country’s annual quota at 2 percent of the number of foreign-born people of that nationality living in the continental United States according to the 1890 census, with a floor of 100 for any country.1San Diego State University. Immigration Act of 1924 – Section 11 The total came to roughly 164,667 slots per year.
Congress picked the 1890 census on purpose. By that year, the large waves of arrivals from Italy, Poland, Russia, and other parts of Southern and Eastern Europe had not yet occurred. Anchoring the formula to earlier population data guaranteed that the countries dominating earlier immigration — Great Britain, Ireland, and Germany — would collect the largest share of visas.
The effect was dramatic. Under the earlier Emergency Quota Act of 1921, quotas had been calculated at 3 percent of foreign-born residents using the 1910 census, which reflected far more Southern and Eastern European immigration.2Office of the Historian. The Immigration Act of 1924 (The Johnson-Reed Act) The switch to the 1890 baseline cut those quotas hard. Italy’s annual allotment dropped from over 42,000 under the 1921 law to fewer than 6,000. Once a country hit its ceiling for the fiscal year, no more visas issued, and unused numbers did not carry over.
The Permanent Formula That Took Effect in 1929
The Act also built in a permanent formula that started on July 1, 1929. Total annual immigration was capped at roughly 150,000, and each country’s share reflected its proportion of the total U.S. population as calculated from the 1920 census, rather than just the foreign-born piece of it.3San Diego State University. Immigration Act of 1924 – Section 11(b) The Secretaries of State, Commerce, and Labor jointly calculated the shares. The 100-per-country minimum stayed in place. The goal did not change: preserve the ethnic composition of the population already in the country.
The Bar on Asian Immigration
The Act’s most sweeping provision had nothing to do with the quotas. Section 13(c) barred the admission of any person “ineligible to citizenship” under existing law.2Office of the Historian. The Immigration Act of 1924 (The Johnson-Reed Act) Federal naturalization statutes dating to 1790 and 1870 limited citizenship to “free white persons” and persons of African descent. Anyone outside those categories could not naturalize, and under the 1924 Act, could not immigrate either.
This closed a gap left by the Immigration Act of 1917. The 1917 law had drawn an “Asiatic Barred Zone” across southern and southeastern Asia but exempted Japanese nationals because of a separate diplomatic arrangement. By pegging exclusion to citizenship eligibility instead of geography, the 1924 Act captured Japanese immigrants alongside every other Asian nationality.
The Supreme Court Cases That Made It Possible
Two Supreme Court decisions handed Congress the legal architecture. In Ozawa v. United States (1922), the Court held that a Japanese-born man could not naturalize because he was “clearly not a Caucasian” and therefore fell outside the meaning of “free white persons.”4Justia Law. Ozawa v. United States, 260 U.S. 178 (1922) A year later, in United States v. Bhagat Singh Thind (1923), the Court ruled that even a high-caste Indian who could claim Caucasian ancestry under some ethnological classifications did not qualify, because “free white persons” meant white as the term was popularly understood.5Justia Law. United States v. Bhagat Singh Thind, 261 U.S. 204 (1923) Together the rulings confirmed that no person of Asian descent could naturalize, which meant the 1924 Act’s “ineligible to citizenship” bar applied across the board.
The exclusion held regardless of wealth, education, or profession. The Act’s narrow exceptions for diplomats and certain travelers offered no path to permanent residence. Congress avoided naming nationalities in the text, framing the restriction around citizenship eligibility, but the effect was a near-total racial bar and everyone understood it that way.
The Break with Japan
The Asian exclusion provision triggered an immediate diplomatic crisis. Since 1907, the United States and Japan had operated under the Gentlemen’s Agreement, an informal arrangement in which the Japanese government voluntarily restricted the emigration of laborers in exchange for the continued integration of Japanese American children in West Coast schools.2Office of the Historian. The Immigration Act of 1924 (The Johnson-Reed Act) The 1924 Act discarded that arrangement, imposing a statutory ban that drew no distinction between laborers and anyone else.
Japan protested formally. The unilateral abrogation of the Gentlemen’s Agreement was widely read in Japan as a racial insult, damaging a relationship that had been generally amicable since the mid-nineteenth century. Congress had made its calculation and preserved the racial composition of the country over the diplomatic cost.
Visas from Consulates Abroad
The Act also changed how immigrants entered the country. For the first time, every prospective immigrant had to obtain a visa from a U.S. consulate abroad before departing.6U.S. Citizenship and Immigration Services. Visa Files, July 1, 1924 – March 31, 1944 Screening that used to happen at Ellis Island and other ports of arrival moved overseas. Applicants sat for an interview with a consular officer, submitted a formal application with parental information and criminal history, and provided photographs. The officer could refuse the visa if the applicant seemed likely to become a public charge, had certain health conditions, or was otherwise inadmissible. Each visa cost $9 and had to be used within a period set by regulation, not exceeding four months.7U.S. Law and Race Initiative OER. Immigration Act of 1924 – Section 2
Holding a visa did not guarantee entry. The statute said so plainly: if an inspector at the port of arrival found the immigrant inadmissible, the visa did not override that finding. Section 16 fined transportation companies $1,000 per person carried in violation, plus the passenger’s fare from the point of departure.8San Diego State University. Immigration Act of 1924 – Section 16 Shipping lines had strong reason to screen passengers before they boarded.
Who Was Exempt from the Quotas
Section 4 defined categories of “non-quota immigrants” who did not count against the annual caps. These included the wives and minor children of U.S. citizens, immigrants returning from temporary trips abroad, and people born in independent countries of the Western Hemisphere, including Canada, Mexico, Cuba, and the nations of Central and South America.9U.S. Law and Race Initiative OER. Immigration Act of 1924 – Section 4 The Western Hemisphere exemption reflected the U.S. economy’s dependence on cross-border labor and a desire not to antagonize its neighbors.
Certain professionals also qualified. Ministers and college professors with at least two years of continuous practice could enter with their spouses and minor children. Students aged fifteen or older could enter to study at an accredited institution, provided the school reported on their attendance.10San Diego State University. Immigration Act of 1924 – Section 4(e) Non-quota status did not exempt anyone from the health, criminal background, or public charge requirements.
The Border Patrol Arrived the Same Year
Enforcing numerical limits along thousands of miles of land border was a new problem. In 1924, the same year the Johnson-Reed Act took effect, Congress established the U.S. Border Patrol through a separate appropriations measure.11U.S. Customs and Border Protection. Border Patrol History It began as a small force of mounted agents patrolling remote stretches of the northern and southern borders.12U.S. Customs and Border Protection. Border Patrol Overview Before strict caps existed, most people had simply arrived at a port of entry. Once legal entry became impossible for many, unauthorized crossings followed, and the Border Patrol was the enforcement apparatus the quota system needed to function.
Consequences for Refugees in the 1930s
The quota system stayed rigid through the 1930s and into World War II. The United States had no separate refugee admission policy, and everyone fleeing Nazi Germany competed for the same quota slots available to people from their country of birth. The public charge standard required financial sponsorship, layering another barrier onto the quota itself.
Demand overwhelmed supply. The waiting list for the German quota alone grew from roughly 139,000 people in June 1938 to over 309,000 by June 1939. Someone applying from Hungary in 1939 faced an estimated forty-year wait. The German quota was fully used in 1939 for the first time in nearly a decade, with about 27,370 visas issued. Between 1933 and 1941, hundreds of thousands of applications went unfilled.
Congress did not respond until after the war. The Displaced Persons Act of 1948 authorized up to 202,000 visas over two fiscal years for eligible displaced persons, issued outside normal quota limits.13GovInfo. Displaced Persons Act of 1948 – Section 3(b) Even that program required consular officers to charge each visa against the immigrant’s country-of-origin quota for a future year, so the quota structure kept its grip on refugee policy years after its human cost had become unmistakable.
How the Law Ended
The Immigration and Nationality Act of 1952, known as the McCarran-Walter Act, kept the national-origins quota framework but ended the racial bar to naturalization that had blocked Asian citizenship since 1790. Each Asian nation received a minimum quota of 100 visas per year. The revised formula produced roughly 154,277 total annual visas, of which 85 percent still went to people of Northern and Western European lineage.14Office of the Historian. The Immigration and Nationality Act of 1952 (The McCarran-Walter Act) The 1952 law also assigned Asian quotas by race rather than by country of birth, so a person of Japanese ancestry born anywhere counted against the Japanese quota.
The system ended with the Immigration and Nationality Act of 1965, the Hart-Celler Act. It abolished the national-origins quotas outright and replaced them with a preference framework built around reunifying families already in the United States and admitting workers with needed skills. That change closed the era Johnson-Reed had opened and reshaped who could come to the country for generations afterward.
