The Naturalization Act of 1790 was the first federal law setting out how immigrants could become United States citizens. Signed on March 26, 1790, and printed at 1 Stat. 103, it was a single section of roughly 200 words. In plain terms, it allowed any free white immigrant who had lived in the country for two years to apply for citizenship at a common law court, prove good character, and swear an oath to support the Constitution. Once the clerk recorded the proceedings, the person was a citizen.1Constitution Annotated. ArtI.S8.C4.1.2.3 Early U.S. Naturalization Laws2Immigration History. Nationality Act of 1790
The Act carried out the power given to Congress in Article I, Section 8, Clause 4 to establish “an uniform Rule of Naturalization,” replacing the mix of state and colonial-era practices that had governed the question before ratification.
What the Act Required
An applicant had to meet a short list of conditions. Two years of residence somewhere in the United States, and at least one year in the state where the application was filed. Appearance before a common law court of record in that state. Proof of good character to the court’s satisfaction. An oath to support the Constitution of the United States. The clerk then recorded the proceedings, and that record was the applicant’s proof of citizenship.2Immigration History. Nationality Act of 1790
Several things the Act did not require are worth naming, because later laws would add them. There was no declaration of intention filed years in advance; the process was a single court appearance. There was no federal agency reviewing anything. There was no standardized certificate. Any common law court of record in any state qualified, which meant county courts, municipal courts, state courts, and federal courts could all naturalize citizens. Most of the work happened locally.3National Archives. History of the Certificate of Citizenship, 1790-1956
The good character requirement was left undefined. The statute said only that character had to be shown “to the satisfaction of such court.” In practice, that meant producing neighbors or community members who could vouch for the applicant. The local judge decided, and standards varied from courtroom to courtroom.
Who Was Eligible: The “Free White Person” Limit
The opening qualifier of the Act limited eligibility to “any alien, being a free white person.” Six words that, at the federal level, closed the naturalization process to non-white immigrants regardless of how long they had lived in the country. Free Black people, Indigenous people, and immigrants from Asia could not apply.1Constitution Annotated. ArtI.S8.C4.1.2.3 Early U.S. Naturalization Laws
This was not a stray phrase. Some states before 1790 had recognized free Black residents as state citizens, and the federal Act drew a racial line around national citizenship that overrode that ambiguity. The phrase remained in the statute through every revision for eighty years.
Congress first opened naturalization beyond white immigrants in 1870, extending it to people of African nativity and African descent.4GovInfo. Forty-First Congress Sess. II Ch. 254 1870 Asian immigrants remained ineligible. Race was not fully removed from naturalization law until the Immigration and Nationality Act of 1952, more than 160 years after the original Act put it there.
How Children Were Treated
The Act handled children in two separate categories, and the distinction mattered.
Children under twenty-one who were already living in the United States when a parent naturalized became citizens automatically through the parent’s naturalization. No separate filing was needed.2Immigration History. Nationality Act of 1790
Children born abroad to American citizens were declared “natural born citizens.” This provision came with a generational limit: the right did not pass to children whose fathers had never resided in the United States. Congress wanted a tangible connection to American soil somewhere in the family line.2Immigration History. Nationality Act of 1790
The language tied foreign-born children’s citizenship to the father’s residency history, reflecting the eighteenth-century legal doctrine of coverture, under which a married woman’s legal identity was largely absorbed into her husband’s. Whether an American mother could independently pass citizenship to a child born abroad was, at best, unresolved under the 1790 framework.
The Clause on Persons Banished by a State
A final clause, easy to miss, addressed anyone who had been formally banished or outlawed by a state government. Such a person could not use the federal law to gain citizenship unless the legislature of the state that had proscribed them passed a separate act allowing it. The provision acknowledged that some states had expelled Loyalists and others during and after the Revolution, and Congress did not want the new federal rule to overrule those state decisions.
How Long the 1790 Rules Actually Stood
The specific rules of 1790 had a short life. Congress replaced the Act in 1795, raising the residency requirement from two years to five and adding a formal declaration of intention that had to be filed three years before the citizenship application. The single-court-visit process of 1790 was gone.
The Naturalization Act of 1798, passed alongside the Alien and Sedition Acts, pushed the residency requirement to fourteen years and required the declaration of intention five years in advance. When Jefferson’s party took power, the Naturalization Act of 1802 rolled the residency requirement back to five years, roughly where it has stayed since.1Constitution Annotated. ArtI.S8.C4.1.2.3 Early U.S. Naturalization Laws
The five-year standard familiar to modern applicants traces to 1802, not to 1790. What did carry forward from 1790, and proved much harder to dislodge, was the racial restriction. The 1795, 1798, and 1802 revisions all left “free white person” untouched. It was 1870 before Congress opened the door to immigrants of African descent,4GovInfo. Forty-First Congress Sess. II Ch. 254 1870 and 1952 before the racial language disappeared entirely.
Why the Text Still Gets Cited
Two ideas from the Act have outlasted its specific rules. The first is that Congress, not the states, sets the terms of citizenship. Before 1790, states set their own. After it, there was one federal standard, and that has never been reversed. The second is the racial line the Act drew at the outset. Writing “free white person” into the country’s first naturalization law placed racial exclusion inside the legal architecture of American citizenship from the beginning, and every later debate over who could naturalize was, in some form, a response to that starting point. The full text sits at 1 Stat. 103 in the Statutes at Large.
