US Birthright Citizenship 2026: What Changes to Expect

Since 1898

Wong Kim Ark Precedent

EO 14160

Trump Executive Order

Q3 2026

SCOTUS Ruling Expected

For more than 125 years, US birthright citizenship has rested on a single sentence in the 14th Amendment and a single Supreme Court ruling, United States v. Wong Kim Ark (1898), interpreting it. That settled framework is now under direct constitutional review for the first time in living memory. The Supreme Court is preparing to rule on Trump v. Barbara, Docket No. 25-365, in what is expected to be one of the most consequential constitutional cases of the modern era.

For investors, the question is not political. It is operational. The Citizenship Clause has been a quiet but reliable feature of American immigration planning for generations of high-net-worth families: a US-born child is a US citizen, irrespective of the parents' visa status at the time of birth. If the Supreme Court narrows that rule in 2026, the calculus around the EB-5 Immigrant Investor Program, the E-2 Treaty Investor visa, and US real estate planning for family-stage investors changes materially.

This analysis sets out the current rules, the precise scope of the executive order under review, the legal questions before the Court, the realistic range of outcomes, and the strategic options NTL International is reviewing with affected clients.

Current US Birthright Citizenship Rules Under the 14th Amendment

As of May 2026, US birthright citizenship continues to operate under the long-established framework set by two foundational instruments:

The 14th Amendment Citizenship Clause (1868)

The Citizenship Clause, ratified in the aftermath of the American Civil War, provides that "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." Its original purpose was to constitutionally guarantee citizenship to formerly enslaved persons and their descendants, overruling the Dred Scott decision.

The Statutory Codification at 8 U.S.C. § 1401(a)

Congress codified the Citizenship Clause in the Immigration and Nationality Act. The statute states that a person born in the United States, and subject to the jurisdiction thereof, is a US national and citizen at birth. This provision is the operative federal law applied by USCIS, the State Department, and the Social Security Administration when issuing US passports, certificates of citizenship, and Social Security numbers.

United States v. Wong Kim Ark (1898): The Controlling Precedent

The Supreme Court held in Wong Kim Ark that a child born in San Francisco to Chinese immigrant parents who were lawfully resident but statutorily barred from naturalization was a US citizen at birth under the 14th Amendment. The ruling established the territorial principle of jus soli (right of the soil) as the dominant rule in US nationality law, with narrow exceptions limited to children of foreign diplomats, children of hostile occupying forces, and (historically) children of Native American tribes maintaining tribal sovereignty (the latter subsequently resolved by the Indian Citizenship Act of 1924).

The practical effect is straightforward. Any child born on US soil, regardless of the immigration status of either parent, is a US citizen at birth unless one of the narrow Wong Kim Ark exceptions applies. This rule has been administered without serious challenge by every federal administration from 1898 to January 2025.

What Executive Order 14160 Proposes to Change

On January 20, 2025, the first day of his second term, President Trump signed Executive Order 14160, titled "Protecting the Meaning and Value of American Citizenship." The order directs every department and agency of the federal executive branch to decline to issue documents recognizing US citizenship, including US passports and Social Security cards, to a child born in the United States on or after February 19, 2025, in either of the following circumstances:

• The child's mother was unlawfully present in the United States at the time of the birth, and the child's father was not a US citizen or lawful permanent resident at that time.
• The child's mother was lawfully but temporarily present in the United States (for example, on a student, tourist, or work visa) at the time of the birth, and the child's father was not a US citizen or lawful permanent resident at that time.

The constitutional theory behind the order, advanced by the Department of Justice in its briefing to the Supreme Court, is that the phrase "subject to the jurisdiction thereof" in the Citizenship Clause was intended to require something beyond mere territorial presence: a meaningful political allegiance and a permanent (not temporary or unlawful) domicile. On that reading, children of undocumented immigrants and children of temporary visa holders fall outside the clause and are therefore not constitutionally entitled to automatic birthright citizenship.

It is critical to note that, as of May 2026, the order is not in operational effect. Lower courts in the District of New Hampshire and the First Circuit Court of Appeals issued injunctions blocking implementation, and the Supreme Court granted certiorari before judgment to resolve the question on the merits.

Trump v. Barbara at the Supreme Court: The Legal Battle Explained

The litigation now before the Court is captioned Donald J. Trump, President of the United States, et al., v. Barbara, et al., Docket No. 25-365. It originated as a class action brought by the American Civil Liberties Union and affiliated civil rights organizations on behalf of families affected by the executive order. Procedurally, the case reached the Supreme Court through the following path:

• July 10, 2025: The District of New Hampshire granted a classwide preliminary injunction against the executive order.
• September 2025: The government filed notice of appeal to the First Circuit.
• Late 2025: The Supreme Court granted certiorari before judgment, allowing the case to bypass the appellate court and proceed directly to the merits.
• April 1, 2026: Oral argument was held before the full bench of the Supreme Court.

The Single Question Before the Court

The question presented in the government's petition is narrow but determinative: whether Executive Order 14160 complies on its face with the Citizenship Clause of the 14th Amendment and with 8 U.S.C. § 1401(a), which codifies that clause.

The Two Competing Constitutional Theories

The government's position relies on Elk v. Wilkins (1884), in which the Court excluded Native Americans owing primary allegiance to tribal nations from automatic citizenship under the Citizenship Clause. The Solicitor General argues that "subject to the jurisdiction thereof" carries the same meaning today: it requires permanent domicile and meaningful political allegiance, both of which, the government contends, are absent in the case of undocumented and temporary visa-holding parents.

The respondents rely on United States v. Wong Kim Ark (1898), which interpreted the same clause to extend birthright citizenship to virtually every child born on US soil with only the narrow exceptions noted above. The respondents argue that the text, the historical context of the 14th Amendment's drafting, the codification at 8 U.S.C. § 1401(a), and more than a century of consistent administrative practice all foreclose the government's reading.

What the Bench Focused On at Oral Argument

The questioning at oral argument addressed both the substantive constitutional theory and the administrative consequences of a ruling for the government. The bench probed the practical mechanics of how parental immigration status would be verified at the moment of birth, what evidentiary standards would apply, and what would happen to the millions of US citizens whose citizenship has been recognized under the prevailing interpretation. These practical questions, distinct from the pure constitutional analysis, often signal where a majority's discomfort lies.

Three Possible Outcomes for US Birthright Citizenship in 2026

A constitutional ruling at the Supreme Court is rarely binary. Investors and advisors should plan for a range of outcomes rather than a single forecast.

Scenario 1: The Court Strikes Down Executive Order 14160

The most likely outcome based on the weight of precedent. The Court would reaffirm Wong Kim Ark, hold that 8 U.S.C. § 1401(a) and the Citizenship Clause continue to grant citizenship to nearly all persons born on US soil, and rule that the executive branch cannot, by order, redefine constitutional citizenship without a constitutional amendment or explicit congressional action. Under this outcome, the status quo for foreign investors remains intact.

Scenario 2: The Court Upholds the Order in Full

The order takes effect for births on or after February 19, 2025. Children born to E-2 visa holders, B-1/B-2 visitors, F-1 students, and other temporary nonimmigrant status holders would not receive automatic US citizenship. EB-5 applicants whose conditional residency has not yet been granted at the time of birth would also be affected. The order would create the administrative requirement, raised at oral argument, of verifying parental immigration status at every US birth. Substantial implementation litigation would follow.

Scenario 3: A Narrow or Splintered Ruling

The Court may issue a ruling that resolves only part of the question, that distinguishes between undocumented and temporary-status parents, that remands on procedural grounds, or that produces a fragmented plurality without a clear majority rule. This is the planning scenario that should concern advisors most, because it produces sustained legal uncertainty without a clean rule. Different federal circuits, state vital records offices, and federal agencies could end up applying inconsistent standards while implementation litigation works its way back through the system.

How a Ruling Could Affect EB-5 and E-2 Investors

The investor-facing impact of any ruling depends on the parents' immigration status at the moment of the child's birth, not at any later moment. This is the operative legal point that often goes underexamined in commentary on the case.

EB-5 Immigrant Investor Program

The EB-5 process involves an initial Form I-526 / I-526E petition, followed by either consular processing or adjustment of status, leading to conditional permanent residence, and eventually, after two years and a successful Form I-829 petition, full lawful permanent residence. A child born to an EB-5 applicant before conditional residency is granted (a common occurrence given multi-year processing times) is currently a US citizen at birth. Under Scenario 2 or Scenario 3 above, that child's citizenship would become uncertain.

E-2 Treaty Investor Visa

The E-2 visa is, by design, a nonimmigrant status. The investor and dependents are admitted as temporary visitors regardless of how many years of continuous renewal accumulate. Under Scenario 2, children born to E-2 principals or dependents would not receive automatic US citizenship. This is the single largest categorical impact for the investor visa cohort, because the E-2 has historically been used by families precisely on the assumption that US-born children would be US citizens.

B-1/B-2, F-1, H-1B, and Other Nonimmigrant Categories

The same logic applies to short-term business visitors, tourists, students, and (depending on interpretation) certain employment-based nonimmigrant categories. The order's text reaches all parents who are "temporarily present" rather than lawful permanent residents or citizens.

Lawful Permanent Residents and US Citizens

Families in which at least one parent is a US citizen or lawful permanent resident at the time of birth are not affected by the order or by any scenario described above. The 14th Amendment's protection for these children is not in question.
