Anyone entering the United States in 1920 faced a screening regime built almost entirely on the Immigration Act of 1917, and the 1920 immigration laws and requirements that governed admission combined a literacy test, an eight-dollar head tax, a medical inspection, a discretionary “public charge” judgment, a geographic ban covering most of Asia, political disqualifications, and, since the war, a visa issued by a U.S. consulate abroad. About 430,000 immigrants entered through major ports that year. Roughly one in five was detained at Ellis Island for a closer look, and about two percent were sent home.
What Every Immigrant Had to Pass
Two requirements applied to nearly every adult arrival. The first was a literacy test. Every immigrant over sixteen had to read a passage of thirty to forty ordinary words in a language of their choice. Inspectors kept printed cards in dozens of languages for the purpose. The test was designed to filter out people from regions with limited access to schooling, and it worked as intended: Southern and Eastern Europeans failed at markedly higher rates than Northern and Western Europeans.
Exemptions were narrow. Children under sixteen traveling with a parent did not have to take the test. Neither did applicants who could persuade an inspector that they were fleeing religious persecution, a provision used primarily by Jewish refugees from Russia and Eastern Europe.1U.S. Law and Race Initiative OER. Immigration Act of 1917 Elderly parents and grandparents joining family in the United States had a limited exemption that was hard to invoke in practice.
The second requirement was the head tax. Every arriving immigrant aged sixteen or older paid eight dollars at the port. The figure had climbed from the original fifty-cent tax first imposed in 1882. Eight dollars was a real sum for a laborer leaving a war-damaged economy, and for a family arriving together the tax alone consumed a meaningful share of savings.
The Public Charge Judgment
The most powerful ground for exclusion was not a test with a fixed passing score. It was a judgment. The 1917 Act made anyone “likely to become a public charge” excludable, and it gave inspectors enormous discretion to decide who fit that description.2GovTrack. 39 Stat. 874 – Immigration Act of 1917
There was no set dollar amount that guaranteed admission. A woman traveling alone with children, a man with a visible disability, an applicant with vague plans for employment, or anyone carrying too little cash could be refused on this ground alone. The burden of proof sat entirely with the immigrant. Because the standard was subjective, it functioned as a catchall that could be layered on top of any other concern. It was the single most common reason for exclusion in this period.
The Medical Line
The first real test at a port of entry was medical. U.S. Public Health Service doctors stationed along the inspection line had about six seconds per person to spot a problem.3National Park Service. Historic Medical Inspection (2nd Floor) As immigrants filed past, doctors scanned six areas in a glance: scalp, face, neck, hands, gait, and general condition.4United States Public Health Service. Mental Examination of Immigrants: Administration and Line Inspection at Ellis Island
Anyone who raised suspicion was marked with chalk on their clothing. A “C” indicated a possible eye condition, “S” senility, “X” suspected mental illness, and “EX” a case needing general further examination. Chalk-marked immigrants were pulled out and routed to a fuller workup.
Certain findings triggered mandatory exclusion with no appeal. Tuberculosis, venereal disease, trachoma, and favus were classified as “Class A” conditions: loathsome or dangerous contagious diseases. Trachoma, a bacterial eye infection that can cause blindness, was the diagnosis immigrants feared most, because inspectors checked for it by flipping the eyelid with a buttonhook. Epilepsy and other qualifying mental conditions also fell into the mandatory exclusion tier. A separate “Class B” tier covered ailments that would not automatically bar entry but could support a public charge finding.
Who Was Barred by Geography
The 1917 Act drew a line on the map. It defined a vast Asiatic Barred Zone, described by latitude and longitude rather than country names, running roughly from Afghanistan and Arabia in the west through India and Southeast Asia to the Pacific Islands.1U.S. Law and Race Initiative OER. Immigration Act of 1917 Anyone born inside that zone was barred regardless of literacy, health, or resources.
Two significant Asian populations sat outside the statute’s technical reach. Japan was handled separately through the Gentlemen’s Agreement of 1907, under which Japan voluntarily stopped issuing passports to laborers bound for the continental United States and Congress refrained from imposing an outright statutory ban. That arrangement was still in force throughout 1920. Filipinos held a different status as nationals of a U.S. territory, giving them a technical right to enter that did not shield them from severe social discrimination.
Political Disqualifications
The 1917 Act also barred anyone who believed in overthrowing the government by force, opposed organized government as a principle, or belonged to organizations promoting those ideas.1U.S. Law and Race Initiative OER. Immigration Act of 1917 On paper the provisions targeted a narrow slice of political radicals. In 1920 they were an active enforcement tool.
The First Red Scare peaked in early 1920. Attorney General A. Mitchell Palmer authorized coordinated raids across major cities in January of that year, and local police arrested thousands of suspected anarchists and communists, many of them immigrants. The FBI’s own historical account describes the operation as “marked by poor communications, planning, and intelligence about who should be targeted.”5FBI. Palmer Raids Because non-citizens could be deported for their political associations under the 1917 Act, the Justice Department worked with the Department of Labor to convert the arrests into removal proceedings. That linkage between immigration law and domestic political policing shaped what an arriving immigrant with any left-wing affiliation could expect at the port.
Papers Needed Before Boarding
Getting on a ship required paperwork that started long before departure. The Passport Act of 1918 gave the President broad authority to control entry and departure during wartime, making it unlawful for anyone to enter or leave without complying with presidential regulations.6GovInfo. 40 Stat. 559 – An Act To Prevent in Time of War Departure From or Entry Into the United States Contrary to the Public Safety President Wilson’s implementing proclamation designated the Secretary of State as the official who granted aliens permission to enter.7Office of the Historian. Papers Relating to the Foreign Relations of the United States, 1918, Supplement 2, The World War Those wartime controls stayed in effect through 1920, and Congress eventually passed the Passport Act of 1920 to formalize them.
The requirement that immigrants obtain a visa from a U.S. consulate abroad before departure also began as a wartime measure in 1917 and continued under the 1918 act.8National Archives. Department of State Visa Records The screening process now started overseas. A consular officer could deny a visa before the immigrant ever boarded a ship, and for people in remote areas or countries with few U.S. consulates, simply reaching a consulate was its own journey.
Steamship companies carried heavy legal responsibility for every passenger. The 1917 Act required them to maintain detailed manifests recording each passenger’s name, age, occupation, last residence, destination, and financial resources. An inaccurate or incomplete manifest triggered a fine of ten dollars per immigrant whose information was missing or wrong.9Library of Congress. Immigration Laws Shipping lines also faced fines of twenty-five to three hundred dollars for each excludable immigrant they transported, plus the cost of the return voyage. Where prosecuting an individual was impractical, a flat one-thousand-dollar penalty could be imposed as a lien against the vessel.10Justia. United States v. Steamship Coamo Those stakes turned shipping companies into de facto screeners at the point of embarkation.
What Happened at the Port
An immigrant who cleared the medical line moved into legal inspection. Uniformed officials at high desks worked through the passenger manifest data the steamship company had filed, asking questions in quick succession: name, age, occupation, final destination, who was meeting them, how much money they carried, whether they had ever been in prison. Discrepancies between the answers and the manifest raised flags.
Anyone who did not appear “clearly and beyond a doubt entitled to land” was referred to a Board of Special Inquiry, a panel empowered by the 1917 Act to hold hearings and render final decisions on admission or deportation.2GovTrack. 39 Stat. 874 – Immigration Act of 1917 The hearings were closed to the public, and a majority vote controlled the outcome. About ten percent of arriving immigrants went before these boards. Roughly twenty percent were detained at some point, split about evenly between medical and legal holds. The final deportation rate at Ellis Island was about two percent, meaning most detainees ultimately won their hearings or resolved the issue.11National Archives.

Angel Island Was a Different Experience
The Pacific coast process did not resemble Ellis Island. At the Angel Island Immigration Station in San Francisco Bay, arriving passengers were separated by race, gender, and class before disembarking. European travelers and first-class passengers were usually processed aboard ship and released. Asian immigrants, particularly those in steerage, were ferried to the island for far more intensive scrutiny. Where Ellis Island cleared most arrivals in hours, Angel Island detained people for weeks, months, and sometimes years. Chinese immigrants claiming U.S. birth or family ties faced grueling interrogations, with inspectors asking dozens of hyper-specific questions about home villages and family layouts that even truthful applicants sometimes answered inconsistently.
How 1920 Ended the Old System
By late 1920, the screening apparatus was not producing the reductions restrictionists wanted. The literacy test had been expected to sharply cut arrivals from Southern and Eastern Europe, but the numbers rebounded once the war ended. Congress moved toward hard numerical caps.
The Emergency Quota Act of 1921 limited immigration from any given country to three percent of the foreign-born population of that nationality living in the United States as counted in the 1910 census. The choice of the 1910 baseline was deliberate. It captured the population before the peak wave of Southern and Eastern European arrivals, which meant the quotas favored countries like England, Germany, and Ireland and sharply cut allowances for Italy, Poland, and Russia. Nationality was determined by country of birth, with colonies counted separately, and the act required officials to estimate how many 1910 residents would have fallen within newly created postwar countries like Czechoslovakia or Yugoslavia.12U.S. Government Publishing Office. 42 Stat. 5 – An Act To Limit the Immigration of Aliens Into the United States For anyone who arrived in 1920, that shift came just after the fact. They had entered under the last full year of a merit-by-individual system before national origin numbers began to override everything else.
