U.S. Naturalization Oath: Full Text, Waivers, and Ceremony

The U.S. naturalization oath of allegiance is the pledge every applicant recites in a public ceremony to become a citizen, and the moment you finish saying it is the legal instant your citizenship begins. Federal law requires it under 8 U.S.C. § 1448, and its exact wording is set in 8 CFR 337.1.¹

The Full Text You Will Recite

The regulatory oath reads:

I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty, of whom or which I have heretofore been a subject or citizen; that I will support and defend the Constitution and laws of the United States of America against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I will bear arms on behalf of the United States when required by the law; that I will perform noncombatant service in the Armed Forces of the United States when required by the law; that I will perform work of national importance under civilian direction when required by the law; and that I take this obligation freely, without any mental reservation or purpose of evasion; so help me God.²

Inside that single sentence are five distinct promises:

Renouncing allegiance to any foreign country or ruler you were previously a citizen or subject of.
Supporting and defending the U.S. Constitution and laws against enemies both foreign and domestic.
Bearing true faith and allegiance to the United States.
Serving when the law requires it, in one of three forms: bearing arms, performing noncombatant military service, or performing civilian work of national importance.
Taking the obligation freely, with no mental reservation and no plan to evade its terms.

You sign a copy of the oath at the ceremony, and that signed copy becomes part of your permanent naturalization record.

Modified Versions of the Oath

The law recognizes that not every applicant can recite every clause. Two kinds of modification are available.

If you can show by clear and convincing evidence that you are opposed to bearing arms because of religious training and belief, the “bear arms” clause is dropped and you keep the noncombatant service and civilian work commitments. If your religious objection extends to any form of military service, the oath can be narrowed further to include only the civilian-work clause.¹

The statute defines “religious training and belief” as a belief in a Supreme Being that creates duties beyond human relationships. Purely political, sociological, or philosophical views do not qualify, and neither does a personal moral code by itself.¹ The bar is specifically religious, not simply sincere.

Separately, if you object on religious grounds to the words “on oath” or “so help me God,” the regulation lets you substitute “and solemnly affirm” for “on oath” and drop the closing phrase.²

When the Oath Can Be Waived Entirely

Applicants who cannot understand or communicate the meaning of the oath because of a physical or developmental disability or mental impairment can have the requirement waived altogether. When the waiver is granted, the person is still treated as having satisfied the statutory requirement of attachment to constitutional principles.¹

A U.S.-licensed medical doctor, doctor of osteopathy, or clinical psychologist must certify the disability on Form N-648. There is no filing fee for the form, though the professional may charge for the evaluation.³ The same form covers exceptions to the English and civics testing requirements, so many applicants who need an oath waiver have already filed it with their N-400.

Children naturalizing under INA 322 can also have the oath waived if they are too young to understand what it means.¹

The Ceremony Itself

After USCIS approves your N-400, you receive Form N-445, the Notice of Naturalization Oath Ceremony, by mail. It gives you the date, time, and location. The wait from a successful interview to the scheduled oath is typically two to eight weeks. Some USCIS offices run same-day ceremonies where the interview, decision, and oath happen in a single visit.⁴

The back of the N-445 has a questionnaire you must complete in black ink before arriving. It asks about anything that changed between your interview and the ceremony: travel outside the United States, marriage or divorce, arrests or citations, or claiming a tax exemption as a nonresident.⁵ A USCIS officer reviews your answers at check-in. A “yes” to any question may lead to further questioning or delay, but answer honestly. Getting caught in a discrepancy is worse than disclosing an issue up front.

What to Bring

The completed Form N-445 with the questionnaire filled out.
Your Permanent Resident Card, valid or expired. You surrender it at check-in and do not get it back.⁵
Any other immigration documents USCIS specifically told you to bring, such as a reentry permit.

If your Green Card was lost, stolen, or destroyed, USCIS waives the surrender requirement as long as you provided proof of the loss and your recovery attempt at the interview.⁵ USCIS asks that attire respect the dignity of the occasion.

Administrative or Judicial

Ceremonies come in two formats. An administrative ceremony is run by USCIS, often at a USCIS office or a larger public venue. A judicial ceremony is presided over by a federal or state judge, usually in a courtroom.⁵ You don’t choose the format unless you requested a legal name change through the naturalization process, which requires a judicial ceremony because USCIS itself cannot grant name changes.⁶ Requesting a name change can add time to your wait, because USCIS has limited control over judicial ceremony scheduling.

Once everyone is checked in and seated, the presiding officer leads the group in reciting the oath aloud. The moment the last word leaves your mouth is the moment you are a U.S. citizen. Everything before it is process. Everything after it is paperwork.

If You Cannot Attend the Scheduled Ceremony

If you cannot make your date, return the Form N-445 to your local USCIS office with a letter explaining why and asking to be rescheduled.⁵ One missed ceremony with a reasonable explanation is usually manageable.

Missing more than one is where the real risk starts. USCIS presumes an applicant who fails to appear for more than one ceremony has abandoned the application and issues a motion to reopen the previously approved case. You get 15 days to respond and show good cause. If you don’t respond or cannot justify the absences, the officer can grant the motion and deny the application outright.⁴ Years of fees and preparation can be undone by a missed letter.

Your Certificate of Naturalization

At the end of the ceremony you receive your Certificate of Naturalization (Form N-550). Check it before you leave: name, date of birth, country of birth, and certificate number. Typographical errors are far easier to fix in person that day than to correct later.

What to Do Right After the Oath

Citizenship is effective the moment you finish the oath, but several administrative steps still matter.

Apply for a U.S. passport. Your Certificate of Naturalization is the primary document you submit, together with a photocopy, to the Department of State. The original is returned after processing.⁷ A passport is the most portable proof of citizenship and the only accepted document for international air travel.

Update the Social Security Administration. Your SSA record needs to reflect your new citizenship status because it affects future benefit calculations and employment verification.⁸ If you filed the April 2024 or later edition of Form N-400, you may have already requested an SSN update as part of the application, which can spare you a separate trip to an SSA office.⁹

Register with Selective Service if you qualify. Newly naturalized males between 18 and 25 are required to register within 30 days. Failing to register can affect eligibility for federal student aid, government employment, and future immigration benefits for relatives.¹⁰ Registration is free at sss.gov.

Automatic Citizenship for Your Minor Children

One consequence of taking the oath can catch new citizens by surprise. Under 8 U.S.C. § 1431, a child born outside the United States automatically becomes a U.S. citizen when all of these are true at the same time before the child turns 18:

At least one parent is a U.S. citizen, whether by birth or naturalization.
The child is under 18.
The child has lawful permanent resident status.
The child is residing in the United States in the legal and physical custody of the citizen parent.¹¹

There is no required order. The four conditions just need to overlap at a single moment before the child’s 18th birthday. So on the day you take the oath, if your minor child already has a Green Card and lives with you, citizenship attaches to that child automatically.¹² Joint custody counts; sole custody is not required. The rule also covers adopted children who meet the immigration-law definition, and children of military or federal government employees stationed abroad.¹¹

Automatic citizenship does not come with automatic paperwork. To document your child’s status with a Certificate of Citizenship, you file Form N-600 with USCIS. The certificate is not strictly required to establish citizenship, but without it you may hit obstacles enrolling the child in certain programs or obtaining a U.S. passport for them.
