How the U.S. Supreme Court May Rule on Birthright Citizenship: A Deep Dive into Trump v. Barbara

Biazzo Law, PLLC

The United States Supreme Court is once again poised to decide a case that could redefine the meaning of American citizenship for generations to come.

In Trump v. Barbara (No. 25-365), the Court is reviewing whether a presidential executive order limiting birthright citizenship is constitutional. At stake is the scope of the Fourteenth Amendment’s Citizenship Clause—and whether it guarantees citizenship to all persons born on U.S. soil, or only to those whose parents meet certain immigration criteria.

This case presents one of the most consequential constitutional questions of the modern era.

What Is the Case About?

On January 20, 2025, President Trump issued Executive Order 14,160, titled “Protecting the Meaning and Value of American Citizenship.” 

The order attempts to redefine birthright citizenship by excluding:

• Children born to undocumented immigrants, and

• Children born to individuals lawfully present but only temporarily

from automatic U.S. citizenship.

The administration argues that such individuals are not “subject to the jurisdiction” of the United States within the meaning of the Fourteenth Amendment.

Opponents argue that the Constitution guarantees citizenship to nearly all persons born on U.S. soil—regardless of parental status.

The Constitutional Question: What Does “Subject to the Jurisdiction Thereof” Mean?

The Citizenship Clause provides:

“All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens…”

The dispute in Trump v. Barbara centers entirely on how to interpret this phrase.

The Government’s Position

The government argues that:

• Citizenship requires complete political allegiance, not mere physical presence

• Children of undocumented or temporary immigrants lack that allegiance

• The Clause was intended to apply primarily to freed slaves and their descendants

During oral argument, the Solicitor General emphasized that the Clause does not extend to children of temporary visitors or illegal entrants and instead requires a form of domicile-based allegiance.

The Respondents’ Position

Opponents argue that:

• The Fourteenth Amendment codified a territorial rule of citizenship (jus soli) 

• Citizenship depends on birth within U.S. territory, not parental immigration status

• The Supreme Court already resolved this issue in United States v. Wong Kim Ark (1898) 

Why Wong Kim Ark Matters

The 1898 decision in United States v. Wong Kim Ark remains the cornerstone of birthright citizenship law.

The Court held that:

• A child born in the United States to foreign parents (who are not diplomats) is a U.S. citizen at birth 

• Citizenship is grounded in territorial birth, subject only to narrow historical exceptions

Those exceptions include:

• Children of foreign diplomats

• Children of enemy occupiers

• Certain sovereign tribal exceptions

Importantly, these exceptions are tied to lack of sovereign jurisdiction—not immigration status.

Biazzo Law’s Amicus Curiae Brief: Defending the Constitution’s Original Structure

Biazzo Law, PLLC filed its own amicus curiae brief in this case, providing a distinct constitutional perspective grounded in structural principles and Supreme Court precedent.

Key Arguments from the Biazzo Law Brief

The brief emphasizes several critical points:

1. Wong Kim Ark Established a Clear Territorial Rule

The Supreme Court has already constitutionalized birthright citizenship based on place of birth—not parental status.

2. The Government’s “Domicile Theory” Is Legally Flawed

The brief explains that references to domicile in past cases describe factual context—not a constitutional requirement.

3. Stare Decisis Strongly Favors Stability

For over 125 years, Americans have relied on the rule established in Wong Kim Ark. Disrupting that precedent would undermine:

• Legal predictability

• National identity

• Generational reliance interests

4. Executive Power Has Constitutional Limits

The brief highlights a key structural principle:

The Executive Branch cannot unilaterally reinterpret the Constitution to override long-settled Supreme Court precedent.

Instead, any fundamental change to citizenship would require:

• Judicial reconsideration grounded in law, or

• A constitutional amendment under Article V

Key Issues the Supreme Court Must Decide

1. Original Meaning vs. Established Precedent

Will the Court prioritize historical interpretations—or reaffirm settled law?

2. The Role of Parental Immigration Status

Does citizenship depend on the child’s birthplace alone—or also on parental status?

3. Limits on Executive Authority

Can a president redefine constitutional meaning through executive action?

4. Nationwide Legal Consequences

The American Bar Association warns that altering birthright citizenship would disrupt:

• Immigration law

• Criminal law

• Public benefits systems

• Identification and documentation processes

How the Supreme Court May Rule

Most Likely: Strike Down the Executive Order

The Court may reaffirm Wong Kim Ark and hold that birthright citizenship remains intact.

Alternative: Statutory Grounds

The Court could invalidate the order based on conflict with federal law (8 U.S.C. § 1401).

Less Likely: Partial Redefinition

The Court could introduce limits tied to parental status.

Least Likely: Overturn Wong Kim Ark

This would fundamentally transform American citizenship—but would face major legal and historical obstacles.

What This Means for You

The outcome of this case could affect:

• Immigration rights

• Citizenship eligibility

• Constitutional interpretation for decades

If you or your family may be impacted by changes to citizenship law, understanding this case is critical.

Final Thoughts

At its core, this case asks:

Is American citizenship determined by where you are born—or who your parents are?

For over a century, the answer has been clear.

Whether the Supreme Court will reaffirm that principle—or redefine it—will shape the future of the nation.
