Birthright Citizenship in the United States

The Fourteenth Amendment to the United States Constitution guarantees birthright citizenship to every child born “within the jurisdiction of the United States.” The 1898 Supreme Court case of United States v. Wong Kim Ark established an important precedent in its interpretation of the Citizenship Clause of the Fourteenth Amendment in that it cemented birthright citizenship for children of all immigrants. For over a century, anyone born on U.S. soil has automatically been conferred citizenship at birth regardless of their parents’ immigration or citizenship status. While most legal scholars across the political spectrum have maintained that the Fourteenth Amendment interpreted through Wong Kim Ark unequivocally extends birthright citizenship to anyone born in the United States, anti-immigrant political factions have pushed to restrict birthright citizenship—primarily, attempting to deny it to children born in the United States to undocumented immigrant parents. In 2019, then-President Donald Trump announced to reporters that he was looking “very seriously” at ending birthright citizenship, a warning that lacked details and did not come to fruition. On January 20, 2025, one of the first actions President Trump took after being inaugurated was to issue an executive order purporting to deny birthright citizenship to children born of undocumented parents or whose parents are in the country on temporary status. Litigation ensued shortly after the administration issued the order, and its implementation has been blocked by the courts as of January 23.

What is Birthright Citizenship?

Birthright Citizenship

In law, birthright citizenship is simply defined as automatically granting citizenship (as a legal status) to children upon their birth. This status comes in two forms: ancestry-based citizenship (jus sanguinis, a Latin term meaning “right of blood”), or birthplace-based citizenship (jus soli, Latin for “right of the soil).”

Today, many nations use a combination of citizenship through ancestry and citizenship by place of birth to determine birthright citizenship—granting citizenship to some infants based on their parentage and others based on being born within their territory. However, both methods of conveying citizenship can be applied broadly or in more restricted ways. A government can restrict ancestry-based citizenship by imposing residency requirements on the citizen parents, capping the number of generations who can pass citizenship down to a child, or implementing more stringent rules when only one parent is a citizen. It can also restrict birthplace-based citizenship by granting citizenship to babies born on its territory only if their parents hold certain immigration statuses.

	Restricted	Unrestricted
Birthplace-Based Citizenship (Jus Soli)	Anyone born within the state’s territory is a citizen at birth. Restrictions apply based on parent’s citizenship or immigration status.	Anyone born within the state’s territory is a citizen at birth regardless of the parent’s citizenship or immigration status.
Ancestry-Based Citizenship (Jus Sanguinis)	Anyone born to citizen parents is a citizen of the state at birth. Restrictions apply regarding how many generations citizenship can be passed down or if only one parent is a citizen.	Anyone born to citizen parents is a citizen of the state at birth. Little to no restrictions apply on how many generations citizenship can be passed down.

 

Birthright Citizenship in the United States

Currently, the United States uses a combination of unrestricted birthplace-based citizenship (jus soli) guaranteed by the Fourteenth Amendment to the Constitution, and restricted ancestry-based citizenship (jus sanguinis) granted through the Immigration and Nationality Act (INA), as amended by the Child Citizenship Act of 2000, to determine birthright citizenship. The first means that anyone born in the United States is automatically a citizen at birth irrespective of parents’ citizenship status. The second means that children born abroad to at least one U.S. citizen parent may be entitled to U.S. citizenship, if they meet certain statutory requirements. There are more requirements to qualify for U.S. citizenship based on being born abroad to a U.S. citizen parent than there are to qualify for U.S. citizenship based on birth on U.S. soil.

Why Does the United States Grant Citizenship to All Children Born in the Country?

Countries in North and South America generally think about birthright citizenship differently than those in the rest of the world. By and large, granting ancestry-based citizenship is nearly universal throughout the world. On the other hand, granting citizenship to all children born in a country’s territory became more common in the Americas. After the founding of the United States, other countries in the Western Hemisphere also adopted unrestricted birthplace-based citizenship. A 2018 survey found that of the 33 countries in the world that have adopted an unrestricted birthplace-based citizenship model, only six of those are located outside the Americas and the Caribbean. Some researchers have argued that the founders of the United States, in seeking to increase the immigration of “ambitious” Europeans, purposefully adopted birthplace citizenship principles from various existing sources including longstanding theories of natural law and English law. Thus, despite unrestricted birthplace-based citizenship being disproportionately popular among the countries of the Western Hemisphere, none of which is older than the eighteenth century, researchers trace the roots of birthplace-based citizenship to much older traditions adopted by the founders of the United States.

The Fourteenth Amendment and its Interpretations

The concept of birthplace-based citizenship has been established for over 400 years, particularly under English common law. Calvin’s Case was a 1608 English legal decision that shaped American understandings of birthplace-based citizenship. The case ruled that a child born in Scotland would be an English subject under common law and entitled to the benefits of English law. This ruling stipulated that people born on sovereign land, no matter the status of their parents, were “natural subjects” of the kingdom.

The Fourteenth Amendment and the Citizenship Clause

The 1844 New York court case of Lynch v. Clarke was one of the first cases to address the concept of birthplace-based citizenship in the United States, even though it did so in the context of deciding an inheritance in New York. Julia Lynch was born in New York to two Irish parents who were temporary visitors in the United States. Soon after her birth, Lynch and her family returned to Ireland without declaring an intent to be naturalized. Although she remained in Ireland for twenty years after her birth, a U.S. court later used the principle of jus soli, or birthplace-based citizenship, to decide that she was an American citizen at the time of her birth. The Court ruled that her prolonged residence in Ireland succeeding her birth did not affect her birthright citizenship in the United States. Judge Lewis Sandford wrote in 1844, “I can entertain no doubt, but that by the law of the United States, every person born within the dominions and allegiance of the United States, whatever were the situation of his parents, is a natural born citizen. The Lynch case is one of the few examples of how courts at the time applied the basic principle of citizenship based on some people’s birth in the United States.

But such decisions only addressed the citizenship of white persons born in the United States, and those citizenship rights did not apply to all those born inside the country. Thirteen years after Lynch, the Supreme Court’s infamous Dred Scott decision addressed the question of whether the descendants of people who were enslaved and brought to the United States were citizens entitled to the relevant rights and privileges granted to citizens under the Constitution. The Court enshrined the principle that enslaved people and people of African descent were not citizens of the United States, and in doing so rejected birthright citizenship for people of color and abrogated the concept that Black Americans were citizens of the United States by virtue of being born in the country.

The Fourteenth Amendment, which guaranteed certain rights for African Americans in all the states, was enacted following the end of the Civil War and sought to rectify the Dred Scott decision. Among other things, the Fourteenth Amendment sought to ensure birthright citizenship for everyone born on U.S. territory regardless of race.

The first sentence of the Fourteenth Amendment states the following: “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.” While the fight for citizenship recognition continued well after the ratification of the Fourteenth Amendment, the aim of the Amendment was to eliminate the existence of a class of people who were subjected to American law, but excluded from American legal rights. In essence, the use of jus soli to confer citizenship to those born on U.S. soil was to ensure that all those born within the country’s territory, regardless of race, would be citizens. Nevertheless, some groups continued to be excluded from recognition as citizens on the basis of race.  

United States v. Wong Kim Ark

The Fourteenth Amendment became the basis for landmark Supreme Court rulings over the years addressing birthright citizenship. Most notably, the 1898 ruling in United States v. Wong Kim Ark established the explicit precedent that any person born in the United States is a citizen by birth.

The Citizenship Clause’s stipulation about being “subject to the jurisdiction” of the United States had created some uncertainty about who would be excepted on those grounds. Additionally, in the 1880s, Congress began to pass restrictive immigration laws that declared some people permanently ineligible for citizenship, including Chinese immigrants under the Chinese Exclusion Act.

Wong Kim Ark was born in the United States to Chinese parents, though he frequently returned to China on temporary visits. When attempting to return to the United States in 1890, Wong Kim Ark was barred from entering the country under the Chinese Exclusion Act because under the law, he could be excluded from the United States based on his Chinese ancestry.

However, the Supreme Court held in a 6-2 decision that because Wong was born in the United States, and his parents were not “carrying on business” or “employed in any diplomatic or official capacity under the Emperor of China”—implying that these would be the only reasons Wong might not have counted as “subject to the jurisdiction” of the United States—Wong was indeed a U.S. citizen. The Supreme Court noted that application of the Chinese Exclusion Acts could not supersede the mandate of the Fourteenth Amendment.

In a particularly telling passage from the case, the Court asked how citizenship could be denied to children of Chinese immigrants when it extended to children of Scottish, German, and other immigrants. This passage not only underlined that citizenship in the United States was not racially restricted, but specifically established that even though Congress had said that Chinese immigrants themselves could never become U.S. citizens—a law would not be repealed until 1943—their children remained “subject to the jurisdiction” of the United States and therefore qualified for U.S. citizenship at birth. The case clarified that anyone born in the United States was a citizen under the Court’s interpretation of the Fourteenth Amendment, regardless of the parent’s immigration status, and the case has been established precedent for more than 125 years.

In the years since then, the Supreme Court has reaffirmed that undocumented immigrants and their children are “subject to the jurisdiction” of the United States. In its 1982 in Plyler v. Doe, which held that undocumented children have a right to an education under the Fourteenth Amendment, the Supreme Court observed that there is “no plausible distinction” between documented and undocumented immigrants in regard to jurisdiction, as both are “subject to the full range of obligations imposed by [the location’s] civil and criminal laws.”

The Indian Citizenship Act of 1924

Native Americans were one of the last groups in the United States to be granted birthright citizenship. While the government recognized Black Americans’ citizenship with the passage of the Fourteenth Amendment, the government interpreted the law to deny birthright citizenship to Native Americans. The 1884 case of Elk v. Wilkins raised the issue of whether the Fourteenth Amendment’s clause requiring individuals be subject to the “jurisdiction” of the United States to be deemed U.S. citizens included Native American tribes. In this case, John Elk, a Native American born on a reservation, claimed birthright citizenship under the Fourteenth Amendment. However, the Supreme Court ruled in a 7-2 decision that Native American tribes, although located within the territorial limits of the United States, were outside the “jurisdiction” of the United States because tribes were treated as “alien nations, distinct political communities” with whom the United States only habitually dealt with. The court ruled that Native Americans owed immediate allegiance to their tribes, and not the United States. This interpretation was not changed by the ruling in Wong Kim Ark eight years later—after that decision, children of immigrants in the United States were “subject to the jurisdiction” of the government, but for the purposes of citizenship Native Americans still were not.

Through the 1924 Indian Citizenship Act, Congress granted citizenship to all Native Americans born within the territorial limits of the United States. The new law meant that Native Americans were no longer required to shift allegiance from their tribe to the United States as the law no longer recognized that such dual allegiance as a conflict.

Who is Eligible for Birthright Citizenship?

Today, almost everyone born on U.S. territory is automatically granted citizenship at birth.

What Does United States Territory Mean?

The Fourteenth Amendment grants citizenship to people born in the United States and “subject to the jurisdiction thereof.” This includes: the fifty states, U.S. territories, U.S. territorial waters, foreign ships in U.S. internal waters, and airspace above U.S. land, internal waters, and territorial seas. It excludes U.S. registered aircrafts outside U.S. airspace, as well as U.S. military bases, embassies, or consulates abroad.

Who is Excluded from Birthright Citizenship?

The 14th Amendment states that only those “subject to the jurisdiction of the United States” are entitled to citizenship. Children of diplomats have been deemed to not be subject to the jurisdiction of the United States and are therefore not U.S. citizens under the Fourteenth Amendment. Children born to soldiers considered enemy invaders during a hostile occupation of the United States, who are not subject to U.S. law, also are excluded from birthright citizenship.

The recent 2021 decision of Fitisemanu v. United States ruled that unlike Americans born in incorporated U.S. territories, those born in the unincorporated territories of American Samoa are not entitled to birthright citizenship without an act of Congress creating that right. They are considered “non-citizen nationals.”

Can Birthright Citizenship Be Taken Away?

Executive Order 14156: Protecting the Meaning and Value of American Citizenship

On January 20, 2025, President Trump issued Executive Order 14156: Protecting the Meaning and Value of American Citizenship, aimed at ending birthright citizenship for children of undocumented immigrants and those with lawful but temporary status in the United States. The executive order stated that the Fourteenth Amendment’s Citizenship Clause “rightly repudiated” the Supreme Court’s “shameful decision” in the Dred Scott v. Sandford case. However, it continued to argue that the Fourteenth Amendment “has never been interpreted to extend citizenship universally to anyone born within the United States.” The executive order claimed that the Fourteenth Amendment has “always excluded from birthright citizenship persons who were born in the United States but not subject to the jurisdiction thereof.” The order outlines two categories of individuals it claims are “born in the United States and not subject to the jurisdiction thereof,” and thus not automatically extended citizenship: 1) a child of an undocumented mother and a father who is not a citizen or lawful permanent resident; and 2) a child of a mother who is a temporary visitor and a father who is not a citizen or lawful permanent resident. The new order attempts to make ancestry a criteria for acquiring citizenship—it requires children born on U.S. soil to have at least one parent with U.S. citizenship or a green card to be born a U.S. citizen.

 

The order directed government agencies in the United States to stop issuing documents recognizing children under these categories as U.S. citizens. Under this clause of the executive order, for example, the U.S. State Department would be prohibited from issuing U.S. passports to these categories of children. The executive order would also impact the Social Security Administration, prohibiting it from issuing Social Security numbers to children who fall into these categories. While the issuance of birth certificates is not a function of the federal government, the executive order instructs federal agencies not to accept documents from state and local authorities that recognize the U.S. citizenship of children in the identified categories  and to issue guidance about implementing the order within 30 days of its issuance. The limitations to birthright citizenship set out by the executive order would have applied only to children born after February 19, 2025.

Legal Challenges to the Executive Order

Executive Order 14156 prompted several lawsuits including from several states in multiple jurisdictions, immigrant right groups, and expecting mothers claiming the executive order violates the Fourteenth Amendment of the Constitution as well as federal statute. On January 23, 2025, U.S. District Judge John C. Coughenour of the Western District of Washington issued a Temporary Restraining Order blocking implementation of the executive order in the case filed by the states of Washington, Arizona, Illinois, and Oregon.  On February 5, federal judge Deborah Boardman in Maryland issued a preliminary injunction in the lawsuit filed by expecting mothers. Then, a federal judge in New Hampshire became the third to issue a preliminary injunction on February 10, prohibiting the Trump administration from implementing the executive order. Implementation of the executive order, thus, has been blocked by the courts since January 23 as the cases work their way through the judicial system. Further litigation in these cases is expected. President Trump anticipates that the constitutionality of his executive order will be determined by the U.S. Supreme Court.

According to most legal scholars’ interpretations, unrestricted birthright citizenship to those born in the United States is enshrined in the Constitution through the Citizenship Clause of the Fourteenth Amendment. There are only two exceptions to birthright citizenship: children born to diplomats, and children born to members of foreign armies living on U.S. territory (which does not apply today). Children born to undocumented immigrants or temporary visitors do not fall under either of these exceptions. This is because in overturning Dred Scott v. Stanford, Congress repudiated the derivation of birthright citizenship “based in any way on racial, hereditary, or dependent on a parent’s immigration status.” Birthplace-based citizenship is well-cemented in the cases decided by the U.S. Supreme Court that have addressed this question, starting with Wong Kim Ark more than 125 years ago. In its lawsuit to block the executive order, the State of New Jersey, joined by 19 other jurisdictions, argued that the executive branch does not have the authority to “rewrite or nullify a constitutional amendment;” nor is the branch “empowered by any source of law to limit or receive United States citizenship at birth.” The lawsuits argued that the executive order resurrects the notion of a “caste-based system” that targets individuals for disparate treatment based on their parents’ citizenship status, and directions the country dangerously back to the “reprehensible conception of hereditary birthright citizenship espoused in Dred Scott.”

In issuing his restraining order, Judge Coughenour—a Reagan appointee—called the executive order “blatantly unconstitutional.”

Other Ways of Abrogating Birthplace-Based Citizenship

Because birthplace-based citizenship is enshrined in the Constitution, taking it away  would only be possible through the passage of a new constitutional amendment—requiring a two-thirds vote in both the House and Senate, as well as ratification by three-quarters of the states—or through the radical reinterpretation of the language of the current Fourteenth Amendment by the U.S. Supreme Court, as was anticipated by President Trump. While Congress could also try to restrict birthplace-based birthright citizenship through legislation, this type of legislation would likely violate the Fourteenth Amendment.

Relinquishing U.S. Citizenship

In rejecting the notion that Congress has authority to take away someone’s U.S. citizenship, the Supreme Court’s 1967 decision in Afroyim v. Rusk forcefully recognized the constitutional right to remain a citizen, unless an individual voluntarily relinquishes that right. Under current law, loss of birthright citizenship could only occur through voluntary relinquishment of citizenship via acts that include but are not limited to: declaring allegiance to a foreign state; formally renouncing U.S. nationality; or committing any act of treason or attempting to overthrow the United States.

Conclusion

The Fourteenth Amendment to the Constitution guarantees citizenship to any child born within the United States, with limited exceptions. Revoking this right would require amending the U.S. Constitution, or for the U.S. Supreme Court to diverge from centuries of established precedent and legal principles that date back to before the founding of this country.
