Can the Government Take Away U.S. Citizenship? What Naturalized Citizens Need to Know About Denaturalization

TLDR: The U.S. government has always had the legal authority to revoke citizenship, but it’s rarely been used. The Trump administration is now dramatically scaling up denaturalization efforts, targeting naturalized citizens for a wide range of alleged offenses. While constitutional protections and strict legal standards make mass denaturalization difficult, the sheer volume of planned cases is unprecedented. If you are a naturalized citizen with concerns about your status, now is the time to understand your rights and speak with an experienced immigration attorney.

The U.S. Government Is Coming for Some Citizenships. Here’s What You Need to Know

Becoming a U.S. citizen is one of the most significant milestones in an immigrant’s life. Years of work, paperwork, legal hurdles, and waiting, all leading to that moment when you raise your right hand and take the oath. It feels permanent. For most people, it is.

But here’s something many naturalized citizens don’t know: U.S. citizenship can, in certain circumstances, be taken away. The legal term for this is denaturalization, and it’s been part of U.S. law for over a century. What’s changed recently is the scale at which the government is pursuing it.

The U.S. immigration legal process is overwhelming and complex, and when the rules change, it can feel even more disorienting. That’s especially true when it’s your citizenship, not just a visa or a green card, that’s being called into question. Nobody should have to navigate this alone, and understanding what’s happening and what it means for you is the first step.

What Is Denaturalization?

Denaturalization is the legal process by which the U.S. government revokes a naturalized citizen’s citizenship. It’s important to understand from the start: this does not apply to people who were born U.S. citizens. It applies only to individuals who obtained their citizenship through the naturalization process.

The legal foundation for denaturalization dates back to the Naturalization Act of 1906, which was the first federal law to formally allow the government to revoke citizenship, originally for reasons like fraud and failure to demonstrate “good moral character.” Over the decades, Congress reshaped those rules, and the courts stepped in to add significant constitutional guardrails.

Today, the governing law is the Immigration and Nationality Act of 1952 (INA), which limits denaturalization to very specific circumstances, most notably where citizenship was obtained through fraud, willful misrepresentation, or what the law calls “illegal procurement.”

The Supreme Court has made it clear: citizenship is a constitutional right protected by the Fourteenth Amendment. The government cannot strip it away arbitrarily or without ironclad evidence. The standard of proof required, “clear, unequivocal, and convincing evidence”, is considered roughly equivalent to the criminal standard of proof beyond a reasonable doubt.

In short: denaturalization has always been legally possible, but constitutionally constrained and historically rare.

A Sharp Departure: The Trump Administration’s Denaturalization Push

Here’s where things get serious for naturalized citizens paying attention to immigration policy right now.

Between 1990 and 2017, the United States averaged 11 denaturalization cases per year. That number is not a typo. Denaturalization proceedings have been extraordinarily uncommon throughout modern U.S. history.

The Trump administration is proposing something dramatically different.

The Department of Justice (DOJ) has distributed a memo directing U.S. attorneys across the country to pursue denaturalization cases that are “sufficiently important.” The priority categories outlined include:

• Individuals who furthered the interests of gangs or cartels
• Those who committed human trafficking offenses
• Those who committed financial fraud against the United States, private individuals, or companies
• Those who obtained naturalization through fraud or government corruption

The DOJ has now assigned denaturalization cases to 39 U.S. attorney’s offices nationwide and has identified an initial wave of 384 foreign-born Americans whose citizenship it intends to pursue for revocation. Internal targets reportedly call for 100 to 200 possible cases per month, translating to approximately 2,400 annual referrals. That’s more than a 200-fold increase over historical norms.

This is not a minor policy shift. It represents a fundamental change in how aggressively the government intends to use denaturalization as an enforcement tool.

How Does Denaturalization Actually Work?

If you’re wondering what the process looks like, here’s a plain-language breakdown.

Civil Denaturalization

In most cases, denaturalization proceeds civilly, meaning the government files a complaint in federal court in the district where the naturalized citizen lives. There is no jury. A judge decides the case.

The government must prove, with clear and convincing evidence, one of the following:

• The person failed to meet a statutory requirement for naturalization (such as the good moral character requirement), or
• The person willfully concealed or misrepresented a material fact that, had it been known, would have prevented them from obtaining citizenship.

There is no statute of limitations for civil denaturalization, meaning the government can theoretically pursue cases going back decades. However, the evidentiary standard remains extremely high, and each case demands significant resources from both the government and the courts.

Criminal Denaturalization

Criminal denaturalization is tied to an actual criminal conviction, typically under a federal statute that makes it a crime to knowingly and unlawfully procure naturalization. Criminal cases carry the full weight of constitutional criminal protections, including the right to counsel, and are subject to a 10-year statute of limitations. The standard is proof beyond a reasonable doubt.

Importantly, if a person was lawfully eligible for citizenship at the time of naturalization, that is a complete defense, even if procedural irregularities occurred.

What Happens After Denaturalization?

If the court grants denaturalization, the individual’s citizenship is revoked. They must surrender their naturalization certificate and any documentation of U.S. citizenship. The DOJ notifies the Department of Homeland Security and the State Department.

In most cases, the individual reverts to their prior immigration status, often lawful permanent resident (LPR). From there, they may become subject to removal proceedings under federal deportability grounds. This process can take years and requires an enormous investment of legal resources on all sides.

Why Mass Denaturalization Is Harder Than It Sounds

Despite the administration’s ambitious targets, legal experts and immigration practitioners widely acknowledge that implementing denaturalization at the proposed scale faces serious practical and legal barriers.

The Evidentiary Bar Is High

Courts have consistently applied a rigorous standard of proof in denaturalization cases. Because citizenship is a fundamental right, the government cannot meet that standard through procedural shortcuts. Every case must be individually litigated before a federal judge; no shortcuts, no bulk processing.

Capacity Constraints Are Real

Many U.S. attorney’s offices are already stretched thin, dealing with a significant backlog of immigration-related civil litigation. Shifting substantial attorney time toward denaturalization cases pulls resources from other enforcement priorities. The infrastructure to handle thousands of these cases annually simply doesn’t exist in its current form.

Constitutional Protections Are Firmly in Place

The Supreme Court has been consistent over decades: denaturalization cannot be used as a political weapon. It requires individualized findings, proper judicial process, and evidence that meets a very high legal threshold. These protections don’t disappear because of a change in administration.

None of this means the risk is zero. It means the risk is targeted and process-dependent, which is exactly why anyone with concerns should seek legal counsel.

What This Means for Naturalized Citizens

If you are a naturalized U.S. citizen, here is the honest truth: if your naturalization was obtained lawfully and honestly, you are on firm legal ground. The constitutional framework protecting citizenship is robust and has been affirmed repeatedly by the courts.

That said, if there are any circumstances in your naturalization history that you have questions about like information that may not have been fully disclosed, prior legal issues, or anything that felt complicated at the time, now is not the time to wait and hope for the best.

Knowledge Is Your First Line of Defense Against Denaturalization

Denaturalization has always existed as a legal tool, but the proposed scale of its use under the current administration is genuinely unprecedented. For the vast majority of naturalized citizens, the constitutional framework remains protective and the legal barriers to mass denaturalization are real.

But the landscape is shifting, and staying informed matters. Understanding how denaturalization works, what the legal standards are, and what your rights look like is not alarmism, it’s smart.

Frequently Asked Questions

Q: Can the government denaturalize a citizen who hasn’t committed a crime?

A: It’s complicated, but the short answer is: rarely, and with significant legal hurdles. Civil denaturalization doesn’t require a criminal conviction, but the government must still prove by clear and convincing evidence that citizenship was obtained through fraud or illegal means. Without that level of proof, denaturalization cannot succeed. Constitutional protections under the Fourteenth Amendment are firmly on the side of the naturalized citizen.

Q: I became a U.S. citizen years ago. Am I at risk?

A: If you were truthful and met all legal requirements when you naturalized, your citizenship is on solid ground. There is no statute of limitations for civil denaturalization, which means cases from the distant past are theoretically possible, but the evidentiary standard remains very high. If you have any concerns about your naturalization history, an immigration attorney can review your case and give you an honest assessment.

Q: What should I do if I receive any communication from the DOJ or DHS about my citizenship?

A: Contact an experienced immigration attorney immediately. Do not respond to government inquiries without legal representation. You have rights in this process, and how you respond from the very beginning can make a significant difference in the outcome. At Berardi Immigration Law, we’re here to help you understand your situation and protect your status.
