American citizens cannot be deported. Federal immigration law limits removal to people who are not U.S. citizens or nationals, and the Supreme Court has held that the government cannot take citizenship away without the person’s voluntary consent. That protection is close to absolute, but it has edges: naturalized citizens can lose status through a court process called denaturalization, any citizen can give up nationality voluntarily, and citizens are sometimes wrongfully detained by enforcement agents working from incomplete records.
Why the Law Excludes Citizens From Removal
The removal system turns on one word. Only “aliens” can be deported, and federal law defines an alien as any person who is not a citizen or national of the United States.1Office of the Law Revision Counsel. 8 USC 1101 – Definitions Immigration judges are authorized only to decide whether an alien is inadmissible or deportable.2Office of the Law Revision Counsel. 8 USC 1229a – Removal Proceedings If you are a citizen, an immigration court has no jurisdiction over you.
The Fourteenth Amendment backs this up: “All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States.”3Congress.gov. U.S. Constitution – Fourteenth Amendment In Afroyim v. Rusk (1967), the Supreme Court held that Congress has no general power to revoke citizenship without the citizen’s assent. Vance v. Terrazas (1980) reinforced that rule, requiring the government to prove both a voluntary expatriating act and a specific intent to give up citizenship before nationality can be lost.
One boundary worth naming: people born in American Samoa and Swains Island are generally nationals but not citizens.4U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part A Chapter 2 – Becoming a U.S. Citizen The statutory definition of “alien” excludes nationals as well, so non-citizen nationals also cannot be deported.1Office of the Law Revision Counsel. 8 USC 1101 – Definitions
Denaturalization: The One Way Citizenship Can Be Taken Away
Naturalized citizens have the same legal protections as those born on U.S. soil, with a single exception. The government can go to federal court to revoke naturalization, and there is no time limit. A case can be filed decades after the oath ceremony.
A U.S. Attorney files a civil complaint in federal district court asking the judge to cancel the naturalization order.5Office of the Law Revision Counsel. 8 U.S. Code 1451 – Revocation of Naturalization Two grounds are recognized: citizenship was illegally procured, or the applicant concealed a material fact or willfully misrepresented one during naturalization.6U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part L Chapter 1 – Purpose and Background Typical examples are failing to disclose a criminal history, lying about prior immigration violations, or concealing membership in a prohibited organization.
The burden is on the government, and the standard is high: clear, convincing, and unequivocal evidence that the person was ineligible when they took the oath.6U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part L Chapter 1 – Purpose and Background That sits between the “preponderance of the evidence” used in ordinary civil cases and the “beyond a reasonable doubt” required to convict a defendant of a crime.
The Department of Justice has published priorities for denaturalization referrals, focusing on individuals tied to terrorism, espionage, human rights violations, transnational criminal organizations, undisclosed felonies, trafficking, financial fraud against the government, and corruption during the naturalization process.7Department of Justice. CIV Enforcement Memo – Denaturalization Priorities DOJ retains discretion to pursue other cases, so the list is not a ceiling.
The government can also prosecute someone criminally for unlawfully procuring citizenship, which carries prison time in addition to loss of status.8Office of the Law Revision Counsel. 18 USC 1425 – Procurement of Citizenship or Naturalization Unlawfully Once a federal judge signs a denaturalization order, the certificate is canceled and citizenship is treated as if it never existed. The person usually reverts to whatever status they held before naturalizing, often lawful permanent resident, though the underlying fraud may also void the green card. At that point, standard removal proceedings can begin.9Office of the Law Revision Counsel. 8 USC 1227 – Deportable Aliens
Voluntary Loss of Nationality
Any citizen, whether born in the U.S. or naturalized, can lose nationality by performing certain acts with the specific intent to give up citizenship.10Office of the Law Revision Counsel. 8 USC 1481 – Loss of Nationality by Native-Born or Naturalized Citizen Intent is essential. Under Vance v. Terrazas, the act alone does not strip citizenship; the government must prove the person meant to give it up.
Qualifying acts include taking an oath of allegiance to a foreign government, serving in a foreign military engaged against the United States, holding a foreign government position that requires an oath of allegiance, and formally renouncing citizenship before a U.S. consular officer abroad.10Office of the Law Revision Counsel. 8 USC 1481 – Loss of Nationality by Native-Born or Naturalized Citizen
Formal renunciation is the most common path. You must appear in person at a U.S. embassy or consulate in a foreign country, sign an oath of renunciation, and pay a processing fee.11U.S. Department of State. Relinquishing U.S. Nationality Abroad That fee dropped in 2026 from $2,350 to $450, effective April 13, 2026.12Federal Register. Schedule of Fees for Consular Services – Fee for Administrative Processing of Request for Certificate of Loss of Nationality You cannot renounce citizenship from inside the United States.
Once loss of nationality is finalized, you are an alien under federal law. If you later enter the United States without proper immigration authorization, you can be detained and removed like any other non-citizen.
When Actual Citizens Get Caught in Enforcement
The law is clear that citizens cannot be removed. Enforcement runs on databases and paperwork, and both fail. When government records do not reflect a person’s naturalization, birth on U.S. soil, or citizenship acquired through a parent, agents may proceed with detention and removal as if the person were deportable. People who are indigent, have limited English proficiency, or struggle with mental health challenges are most exposed, because they are least equipped to assert their status under pressure.
These situations are documented. Congressional records from 2025 describe multiple U.S. citizens, including children, who were detained and in some cases physically removed from the country.13Congress.gov. House Judiciary Committee – Documented Cases of U.S. Citizens Detained by ICE Citizens were held for days or weeks in several instances. At least one native-born child was deported to Mexico. A Navajo citizen was detained for nine hours. A U.S. military veteran born in Puerto Rico was detained after a traffic stop.
Immigration proceedings are civil, not criminal. That means you have no Sixth Amendment right to a government-appointed lawyer even if you cannot afford one. You can hire an attorney, but if you lack the resources, you navigate the system alone. Most wrongful removal cases collapse in that gap: a person who could easily prove citizenship with the right document or the right phone call gets processed through a system built for speed.
Derivative Citizens Without Documents
Some people are U.S. citizens and don’t know it. Others know but have nothing on paper to prove it. Both situations feed the same problem.
Under the Child Citizenship Act, a child born abroad automatically becomes a U.S. citizen when three conditions overlap: at least one parent is a citizen, the child is under 18, and the child is residing in the United States in the legal and physical custody of the citizen parent after being admitted as a lawful permanent resident.14Office of the Law Revision Counsel. 8 USC 1431 – Children Born Outside the United States No application is required. Citizenship attaches the moment the three conditions coincide.
Children living outside the United States can also acquire citizenship through their parents under a separate provision, though the requirements are more involved. The citizen parent must have been physically present in the United States for at least five years, two of them after age 14, and the child must enter the country lawfully and take the oath of allegiance.15U.S. Citizenship and Immigration Services. USCIS Policy Manual Volume 12 Part H Chapter 5 – Child Residing Outside the United States (INA 322) If the parent falls short on physical presence, a U.S. citizen grandparent’s time in the country can count instead.
If you acquired citizenship this way but never obtained documentation, you may look like a deportable non-citizen in every government database. The formal way to prove it is to file Form N-600 with USCIS for a Certificate of Citizenship. Processing times as of 2026 run roughly 4.5 to 14 months, which is far too long to help someone already in ICE custody. Keeping proof accessible in advance, a U.S. passport, a certificate of citizenship, or at least a certified birth certificate, is the single most useful step you can take.
What to Do If You Are Detained
If immigration authorities detain you and you are a U.S. citizen, tell the immigration judge and the ICE officer immediately that you believe you are a citizen.16ICE. Are You a United States Citizen? Do not sign anything, especially a stipulated order of removal, without understanding what you are agreeing to. Ask for a lawyer. ICE is not required to provide one, but you can request a list of free or low-cost legal services.
Gather what proof you can. A certified birth certificate is the strongest evidence for someone born in the United States. If you do not have one, a baptismal certificate, hospital record, or signed affidavit from someone present at your birth can serve as secondary proof.16ICE. Are You a United States Citizen? If you acquired citizenship through a parent, you will need your own birth certificate, your parent’s naturalization certificate or U.S. passport, and your green card. Once you present sufficient evidence to the immigration judge, the judge should terminate proceedings and order your release.
Memorize the phone number of a family member and an attorney before anything happens. Detainees often lose access to personal belongings, and the ability to reach someone outside who can locate your documents may be the difference between quick release and prolonged detention.
Suing After a Wrongful Removal
A citizen who is wrongfully deported or detained can sue the federal government for damages under the Federal Tort Claims Act. The process has two required steps. First, file an administrative claim (Standard Form 95) with the relevant agency, typically DHS. Second, if the agency denies the claim or fails to act within six months, file a lawsuit in federal district court. The deadline for the initial administrative claim is two years from the date of the wrongful act.17Office of the Law Revision Counsel. 28 USC 2401 – Time for Commencing Action Against United States Missing that window permanently bars the claim.
If the agency issues a formal denial, you then have six months from the date the denial notice is mailed to file the federal lawsuit. Damages can include lost wages, emotional distress, physical harm during detention, and other injuries caused by the government’s negligence or intentional misconduct. Attorneys’ fees in cases resolved administratively are capped at 20% of the settlement. Given the deadlines, talk to an immigration attorney as soon as possible after a wrongful removal.
