Can the government revoke U.S. citizenship once granted?

On Behalf of | May 20, 2026 | Denaturalization

Citizenship is one of the most significant legal statuses a person can hold in the United States. For the millions of naturalized citizens living in New York and across the country, a common question is whether that status is truly permanent or if the government can take it away.

Constitutional shields for citizenship

The 14th Amendment establishes that all persons born or naturalized in the U.S., and subject to its jurisdiction, are citizens of both the country and the state where they reside. If you were born on U.S. soil, the authorities cannot strip your citizenship against your will.

For naturalized citizens, the protections are more nuanced. The Supreme Court has long established that naturalized citizens hold the same rights as those born here, but Congress retains the power to set conditions on how individuals obtain citizenship and, in limited cases, how the government can revoke it.

Legal grounds behind revocation

The federal government can pursue revocation on two primary grounds. The first is illegal procurement, which means you did not meet the legal requirements for naturalization at the time the authorities granted it. This applies regardless of whether intentional fraud was involved.

The second one is concealment or misrepresentation, which involves a deliberate failure to disclose key information during the naturalization process. For this, the government must show the misrepresentation was material and played a role in obtaining your citizenship.

Federal mechanisms of denaturalization

Denaturalization proceedings take place in federal district court, not through an administrative process. In civil cases, the authorities must prove its claims by clear, convincing and unequivocal evidence, a higher bar than most require.

In New York, the U.S. Attorney’s Office files the complaint in the court where you live. The case follows standard civil procedures, though a ruling against you can seriously affect your immigration status and your right to remain in the country.

Legal options for your defense

If you learn that your citizenship is under review, consulting an immigration attorney can help. These cases move through the federal courts rather than immigration courts, a distinction that calls for a different legal approach and knowledge of civil procedure.

You have the right to contest the government’s claims and present evidence in your defense. Possible arguments include challenging whether an alleged omission was truly material or showing that any error was unintentional. You may also be able to demonstrate that you met all legal requirements at the time you received citizenship.
