The Future of Birthright Citizenship Explained

When a baby is born in the United States, they are automatically a U.S. citizen. This powerful rule is known as birthright citizenship—if you are born on U.S. soil, you are a citizen, regardless of your parents' nationality.

While often framed as a modern controversy in heated immigration debates, this principle has been a cornerstone of American law for over 150 years. Its future depends on its past, the core legal arguments, and the potential paths for change that could redefine who becomes an American citizen.

Why Was the Rule "Born Here, Citizen Here" Created?

The rule of birthright citizenship was forged in the aftermath of the Civil War and formally established with the ratification of the 14th Amendment in 1868. Its original purpose was not about contemporary immigration but about righting one of the nation’s deepest wrongs.

Before the amendment, the Supreme Court's 1857 Dred Scott decision declared that people of African descent, whether enslaved or free, could not be American citizens. This ruling wrote racial discrimination into the country’s constitutional fabric.

To permanently overturn that decision and secure the rights of formerly enslaved people, Congress passed the 14th Amendment. Its first sentence, the Citizenship Clause, is direct and powerful: "All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States." This language was a deliberate guarantee that the injustice of the Dred Scott decision would not be repeated. While today’s debates link birthright citizenship to immigration, its origin is fundamentally a story of civil rights—a promise of belonging and equality.

Jus Soli vs. Jus Sanguinis: U.S. Citizenship in a Global Context

The American "born here, citizen here" rule is not the only way countries handle citizenship. Globally, nations generally follow one of two main systems:

1. Jus Soli ("Right of the Soil"): Citizenship is granted to anyone born within a country’s territory. The U.S. and Canada are prime examples.
2. Jus Sanguinis ("Right of the Blood"): Citizenship is inherited from one's parents. This is common in many European and Asian nations, like Italy and Japan, where birthplace matters less than parentage.

After the 14th Amendment, a critical question remained: did it apply only to the children of citizens or to everyone born on U.S. soil? The Supreme Court settled this in the 1898 landmark case, United States v. Wong Kim Ark.

Wong Kim Ark was born in San Francisco to Chinese parents who were not U.S. citizens. When denied re-entry after a trip abroad, he sued. The Supreme Court sided with him, ruling the 14th Amendment’s guarantee applied to him because he was born in the U.S. This decision affirmed that America’s jus soli rule extends to the children of non-citizens, a precedent that has stood for over a century.

The Five Words Fueling the Debate: "Subject to the Jurisdiction Thereof"

The modern debate over birthright citizenship zeroes in on five words in the 14th Amendment: "subject to the jurisdiction thereof." The controversy rests on two competing interpretations of this phrase.

For over 100 years, the prevailing view, supported by the Supreme Court, is that "jurisdiction" means being subject to American laws. Anyone physically present in the U.S. must obey its laws and answer to its courts. By this logic, any child born here—with the rare exception of children born to foreign diplomats—is a citizen.

However, a more restrictive argument has gained traction. This viewpoint claims "jurisdiction" implies complete political allegiance, the kind of undivided loyalty a citizen owes a country. In this reading, a newborn's parents would need a formal legal tie to the U.S. for their child to be "subject to the jurisdiction thereof" in the fullest sense. This is the central legal challenge to birthright citizenship as we know it, impacting children of undocumented immigrants, visa holders, and tourists.

How Could Birthright Citizenship Be Changed?

Given the disagreement, altering this long-standing rule would require navigating monumental legal and political hurdles. There are three theoretical pathways: a constitutional amendment, a new Supreme Court decision, or a presidential executive order.

1. Constitutional Amendment: This is the most permanent but most difficult method. It requires a two-thirds majority vote in both the House and Senate, followed by ratification from three-quarters of the states. The incredibly high bar makes this path unlikely.

2. Supreme Court Ruling: A more discussed route involves the Supreme Court hearing a new case that directly challenges the Wong Kim Ark precedent. If the justices adopted the restrictive interpretation of “subject to the jurisdiction thereof,” they could set a new legal standard, narrowing eligibility for citizenship at birth.

3. Executive Order: Can a president end birthright citizenship by executive order? The overwhelming consensus among legal scholars is no. An executive order cannot override the Constitution. Any such attempt would be immediately challenged in court and, based on existing precedent, would almost certainly be blocked.

The Past, Present, and Future of American Belonging

The principle of birthright citizenship—born from the struggle for civil rights after the Civil War—remains a cornerstone of American identity. Its foundation rests on the 14th Amendment, reinforced by the Wong Kim Ark Supreme Court decision.

Today's debate hinges on the interpretation of five constitutional words: "subject to the jurisdiction thereof." While changing this precedent faces immense legal barriers, the discussion highlights the ongoing tension between two visions of national identity: one based on soil and one on allegiance. Understanding these historical, legal, and political dimensions is essential to navigating the conversation about who is, and who will be, an American.
