The Battle Over Birthright Citizenship: History, Legal Precedent, and Modern Political Debates

Political seasons routinely thrust foundational questions of American identity back into the national spotlight, and few tenets are as deeply woven into that identity as birthright citizenship. As the political landscape shifts ahead of upcoming elections, proposals to alter or revoke citizenship by birth for the children of undocumented immigrants have once again captured the public discourse. Former President Donald Trump, the Republican presidential nominee, has proposed using an executive action on his very first day in office to strip birthright citizenship from future children born to undocumented parents. However, some conservative allies and legal advisors have pushed the envelope even further, arguing for the denial of birthright citizenship to all children born to non-citizens. Legal scholars note that such a sweeping interpretation would fundamentally undermine the foundational premise of the Fourteenth Amendment, which explicitly dictates that all persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens.

This ongoing debate strikes at the heart of what it means to be an American. Proposals to limit birthright citizenship directly challenge more than 125 years of established legal practice, a tradition extending straight back to judicial interpretations of the Fourteenth Amendment and, fundamentally, to the founding of the nation itself. Yet, recent years have witnessed the rise of a distinct public policy infrastructure aimed at redefining and restricting birthright citizenship. This movement is largely fueled by public anxieties surrounding both legal and illegal immigration. Proponents of the most extreme viewpoints argue that neither the children of undocumented immigrants nor the children of legal immigrants who have not yet completed the naturalization process possess a constitutional right to citizenship by birth. Furthermore, advocates of this restrictive perspective insist that stripping birthright citizenship from marginalized groups can be achieved through executive action or simple legislation, avoiding the arduous process of amending the Constitution entirely. As this contentious issue gains significant traction, a closer examination of the historical context, legal precedents, and constitutional debates reveals the complexities likely to shape the road ahead.

The Fourteenth Amendment

Why was the Fourteenth Amendment necessary in the first place?

Although birthright citizenship had been practiced in the United States since its founding, it historically excluded specific classes of people, most notably Native Americans and enslaved Africans. The situation escalated dramatically with the Supreme Court’s infamous 1858 Dred Scott decision, which went far beyond previous exclusions by declaring that all people of African descent—whether enslaved or free, and regardless of whether they lived in slave states, free states, or federal territories—could never become U.S. citizens. This judicial ruling helped ignite the Civil War, the deadliest conflict in American history. Following the war, a determined Congress sought to ensure that newly emancipated Black Americans would not be stripped of their fundamental rights in former Confederate states. Lawmakers also wanted to guarantee that African Americans retained the right to citizenship no matter where they resided in the country, effectively overturning the Dred Scott precedent.

When Congress passed the Fourteenth Amendment, did members intend its protections to extend only to former slaves and other individuals of African descent?

Congress passed, and the states subsequently ratified, the Reconstruction Amendments—the Thirteenth, Fourteenth, and Fifteenth Amendments—within the span of five years following the end of the Civil War to address specific injustices suffered by African Americans. The Thirteenth Amendment abolished slavery nationwide, while the Fifteenth Amendment guaranteed that neither the federal government nor any state could deny citizens the right to vote based on race, color, or previous condition of servitude.

However, the Fourteenth Amendment, which stands as the most complex and far-reaching of the Reconstruction amendments, makes no explicit reference to slavery or race. Instead, it states plainly: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside." The U.S. Senate debated the meaning of citizenship within the amendment at great length. The historical record of those debates and their ultimate resolution make it clear that the language was intended to grant birthright citizenship to virtually everyone born within the territorial boundaries of the United States, subject only to a few minor and well-defined exceptions.

How do opponents interpret the phrase "subject to its jurisdiction"?

Critics of birthright citizenship for the children of non-naturalized immigrants frequently fixate on the phrase "and subject to its jurisdiction" as a disqualifying clause for children born to parents who lacked legal status at the time of birth. However, organized political movements seeking to restrict birthright citizenship go significantly further. Prominent restrictionist advocates argue that only the children of native-born Americans and naturalized immigrants are eligible for citizenship by birth. Under this expansive exclusion, children born to lawful permanent residents, temporary workers, international students, and other foreign nationals who have not yet attained full citizenship would be denied birthright citizenship. Their central legal theory posits that non-naturalized individuals are not subject to the complete political jurisdiction of the United States, but rather to a mere partial territorial jurisdiction.

What did the framers of the amendment mean by "subject to its jurisdiction"?

The congressional debates surrounding the amendment were extensive and occasionally contentious, focusing primarily on three distinct categories of people: the children of foreign diplomats born on U.S. soil, Native Americans, and certain groups of foreign immigrants. One of the principal sponsors of the amendment, Senator Jacob Howard of Michigan, whose proposed language ultimately became the final text of the opening sentence of Section 1, directly addressed the intended exclusions. When asked what limitations the phrase "subject to the jurisdiction" implied, Senator Howard explained that the amendment simply declared existing law, affirming that every person born within the limits of the United States and subject to their jurisdiction automatically became a citizen by virtue of natural and national law. He noted that the clause naturally excluded children born to foreign ambassadors or ministers accredited to the U.S. government, but explicitly included all other classes of people, thereby settling the broad question of citizenship once and for all.

Why did the amendment exclude Native Americans?

Native Americans did not secure full rights of citizenship, including the right to vote, until the passage of the Indian Citizenship Act of 1924. Historically, the relationship between the United States government and Native American tribes was defined by conflict, discrimination, and open warfare. During the period leading up to and immediately following the adoption of the Fourteenth Amendment, the federal government largely regarded Native Americans as members of sovereign nations with which the United States maintained treaty relations or engaged in active hostilities. Throughout the nineteenth century, numerous military conflicts occurred between federal forces and various tribes. By 1866, the United States signed treaties with five tribes in the territory that would become Oklahoma, requiring them to end slavery and extend rights to formerly enslaved Black individuals, illustrating the complex, separate status tribal nations held under contemporary law.

How were the children of foreign immigrants living in the U.S. at the time viewed?

During the drafting process, several senators suggested that additional groups should be excluded from birthright citizenship, including Chinese immigrants and other populations described in overtly xenophobic or racist terms. Senator Edgar Cowan of Pennsylvania expressed severe reservations, warning colleagues that California might be overrun by waves of foreign immigrants or individuals with vastly different religions, manners, and traditions. He questioned whether the local populace would be rendered powerless to protect itself.

In sharp contrast, Senator John Conness of California—himself an immigrant from Ireland—vocalized strong opposition to Cowan’s nativist arguments. In a detailed and impassioned response, Conness defended the inclusion of children born to Chinese parents in California, arguing that any child born on U.S. soil deserved to be treated as an American citizen with identical civil rights and equal protections under the law. He maintained that denying fundamental civil rights to human beings born within the nation ran entirely counter to the basic principles of humanity.

Did the framers anticipate large numbers of children born to non-citizen parents?

The nineteenth century witnessed large-scale immigration to the United States, which regularly triggered fierce political backlashes. A powerful nativist movement during the 1850s—exemplified by the Know Nothing Party, later known as the American Party—achieved significant electoral successes at local, state, and national levels, even running former President Millard Fillmore as their presidential candidate in 1856. The Know Nothings were intensely anti-immigrant and particularly hostile toward the large influx of Catholic arrivals from Ireland.

The 1860 census recorded that more than 13 percent of the U.S. population was foreign-born, a figure remarkably close to modern percentages, though slightly lower than the foreign-born peaks of 1870, 1890, and 1910. Senators debating the Fourteenth Amendment were acutely aware of these mid-century demographic shifts. Yet, none of them suggested that citizenship should be restricted exclusively to children whose parents had completed the naturalization process, especially given that naturalization was uncommon for many immigrants at the time, particularly women. Nineteenth-century naturalization procedures bore little resemblance to modern standards; certificates were often issued without federal oversight, record-keeping was chaotic, and regulatory standards lacked uniformity. Consequently, requiring parents to be naturalized citizens for their children to qualify for birthright citizenship would have been wholly impractical.

How did the concept of undocumented immigration figure into the Fourteenth Amendment?

The modern administrative category of "illegal immigrants" was entirely foreign to the drafters of the Fourteenth Amendment. At that time, the United States maintained essentially open borders, with minimal restrictions on who could immigrate—barring only criminals, prostitutes, and individuals suffering from certain severe mental or physical illnesses. Even these limited restrictions were unevenly enforced until the late nineteenth century.

Following the Civil War, several states attempted to enact their own restrictive immigration policies, but the Supreme Court struck down these state laws in 1875. In the landmark case Chy Lung v. Freeman, the Court ruled that the regulation of foreign citizens arriving on U.S. shores belonged exclusively to Congress, not individual state governments. Nevertheless, the underlying political impulse behind those state laws was a desire to keep out groups deemed undesirable, particularly Chinese laborers who had arrived to help construct western railroads and work in mines.

When state-level restrictions were invalidated, congressional action quickly followed. Congress passed the Chinese Exclusion Act, prohibiting immigration from a specific country for the first time, and subsequently enacted the Immigration Act of 1882, which imposed a head tax on arrivals, established a federal immigration bureaucracy, and authorized broader exclusions.

Has the Supreme Court addressed birthright citizenship for the children of non-citizens?

The Supreme Court definitively addressed the application of birthright citizenship to the children of foreign nationals in the 1898 landmark case United States v. Wong Kim Ark. Wong was born in San Francisco in 1873 to parents who had emigrated from China and established permanent residence in the city. Following the passage of the Chinese Exclusion Act and a surge in anti-Chinese hostility, Wong’s parents returned to China in 1890, accompanied briefly by their teenage son, who returned to California later that same year. In 1895, after visiting his parents in China, Wong was denied re-entry at the port of San Francisco, touching off a three-year legal battle to affirm his American citizenship.

The Supreme Court ultimately ruled that regardless of his parents’ temporary return to China or their foreign ancestry, a child born to individuals domiciled within the United States becomes a U.S. citizen at the moment of birth. Addressing the argument that Wong could not be a citizen because his parents remained subjects of the Chinese Emperor and were legally barred from naturalizing due to exclusionary federal acts and treaties, the majority opinion firmly rejected that logic. The Court held that such statutory bars could not override the broad, clear wording of the Constitution: "All persons born in the United States, and subject to their jurisdiction, are citizens of the United States."

Has the Supreme Court reviewed the Wong Kim Ark precedent?

The Supreme Court has never overturned or revisited the core findings and legal reasoning established in Wong Kim Ark. However, prominent conservative legal figures, such as John Eastman of the Claremont Institute, have periodically urged the judiciary to reconsider the doctrine.

A later case, Hamdi v. Rumsfeld (2004), did not directly address the Fourteenth Amendment’s citizenship clause, but rather focused on Fifth and Fourteenth Amendment due process protections. The case centered on Yaser Esam Hamdi, a U.S.-born man captured while fighting for enemy forces in Afghanistan, and whether he could be detained indefinitely as an enemy combatant without access to a neutral tribunal. In an amicus curiae brief, Eastman argued that Hamdi was not an American citizen despite his birth in Baton Rouge, Louisiana, because his parents were in the country on temporary visas and returned to Saudi Arabia during his early childhood. Notably, not a single Supreme Court justice questioned Hamdi’s status as a birthright citizen, and Justice Antonin Scalia explicitly referred to him as a U.S. citizen.

Are there alternative legal pathways for opponents to alter birthright citizenship?

The primary methods for altering the constitutionally guaranteed right of birthright citizenship are enacting a constitutional amendment or successfully challenging the prevailing judicial interpretation of the Fourteenth Amendment in federal court. Critics have frequently introduced federal legislation aimed at stripping birthright citizenship from the children of undocumented immigrants, but these bills consistently stall. Legal scholars across the ideological spectrum largely agree that such statutory measures would fail constitutional review.

Ironically, revoking birthright citizenship by legislative or executive fiat would instantly swell the undocumented population in the United States by millions of individuals. While altering birthright citizenship remains theoretically possible through a constitutional amendment—requiring a two-thirds vote in both houses of Congress and ratification by three-fourths of state legislatures—such a move would dramatically reshape the foundational character of the nation.

Birthright citizenship remains one of the defining characteristics of American exceptionalism. Throughout its history, the United States has largely functioned as a welcoming nation. While the country’s past features profound moral failures—including slavery and Jim Crow laws that systematically denied full citizenship to millions—the overarching historical trajectory has bent toward the expansion, rather than the restriction, of rights. Through the adoption of the Thirteenth, Fourteenth, Fifteenth, and Nineteenth Amendments, successive generations expanded liberty, citizenship, and voting rights to Black Americans and women. Despite occasional judicial missteps, such as the 1896 Plessy v. Ferguson ruling upholding "separate but equal" accommodations, subsequent courts and legislatures have consistently worked to overturn faulty precedents and enshrine broader protections. For nearly two and a half centuries, the United States has steadily moved closer to fulfilling the ideals articulated in the Declaration of Independence.
