US Citizenship Oath of Allegiance: Text, Waivers, and Ceremony

The US Citizenship Oath of Allegiance is the sworn declaration every naturalization applicant must recite at a public ceremony to become an American citizen. Until you say it, you remain a lawful permanent resident, no matter how far along your case has gone or what the officer told you at your interview. The oath itself is a fixed text set by federal law, and each clause carries a specific legal commitment.

The Full Text of the Oath

As published by USCIS, the 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.”¹

Broken into commitments, you promise to renounce allegiance to any foreign government or ruler, to support and defend the Constitution against all enemies foreign and domestic, to bear true faith and allegiance to the United States, and, when required by law, to bear arms, perform noncombatant military service, or perform civilian work of national importance. The requirement is codified at 8 U.S.C. § 1448, and 8 CFR § 337.1 requires the oath be taken in a public ceremony inside the United States, with the applicant signing a copy of the text.²³

Does the Oath Force You to Give Up Your Other Citizenship?

The renunciation language sounds absolute, but the U.S. State Department’s position is that naturalizing as an American does not require you to surrender citizenship in your home country, and U.S. courts have followed the same approach. You can hold U.S. citizenship alongside another nationality.

What the oath does not control is what your other country does. Some nations automatically revoke citizenship when their nationals naturalize elsewhere. Whether you lose your original citizenship depends on that country’s laws, not on the words you recite here. Check with your home country’s embassy or consulate before the ceremony if this matters to you.

Modifications for Conscientious Objectors

If your religious beliefs or a deeply held moral code prevent you from pledging to bear arms or perform military service, you can request a modified oath that omits one or both of those clauses. You have to show by clear and convincing evidence that the objection is grounded in religious training, a belief system similar to traditional religion, or a deeply held moral or ethical code, and that the belief is sincere and meaningful.⁴

Opposition to a particular war does not qualify. Neither do objections that are essentially political, sociological, or philosophical. USCIS distinguishes sincere belief from public-policy disagreement, and only the first supports a modification.

Waivers for Disability

The oath can be waived entirely for an applicant who cannot understand or communicate an understanding of its meaning because of a physical or developmental disability or mental impairment. The authority comes from 8 U.S.C. § 1448, and when USCIS approves the waiver, the applicant is treated as meeting the attachment requirement without reciting anything.²

A legal guardian, surrogate, or designated representative typically submits a written request along with an evaluation by an authorized medical professional. Form N-648, Medical Certification for Disability Exceptions, can be used, but USCIS does not require that specific form; a written request with a medical evaluation is acceptable.⁴ When the waiver is approved, the applicant does not need to appear at the ceremony at all. The guardian or representative handles the process on their behalf.

This oath waiver is separate from the more common use of the N-648, which excuses an applicant from the English and civics tests at the interview.⁵ An applicant might need one, the other, or both.

Preparing for the Ceremony

After your naturalization interview is approved, USCIS schedules you for a ceremony. Sometimes it happens the same day as the interview. Otherwise, USCIS mails Form N-445, Notice of Naturalization Oath Ceremony, with the date, time, and location.⁶

Form N-445 includes a questionnaire covering only the period between your interview and the ceremony. It asks whether you have married or divorced, traveled outside the United States, been arrested or charged with a crime, joined new organizations, or changed your willingness to bear arms or perform service.⁷ If you answer yes to anything, bring supporting documents such as a marriage certificate, arrest records, or travel documents. Answering dishonestly is grounds for denial.

Bring your Permanent Resident Card, valid or expired, to surrender at check-in. Bring the completed N-445 and any USCIS-issued travel documents. Family and friends are generally welcome, though seating varies by venue.

Travel Risks Before the Oath

You are not a citizen until you recite the oath. If you travel abroad between your interview and the ceremony, you re-enter as a lawful permanent resident. Travel is allowed, but missing your ceremony because you are stuck overseas is a real problem: USCIS may reschedule you once, and if you fail to appear more than once, they can deny the application entirely.⁶

The continuous residence requirement also runs through to the oath. An absence of under six months generally causes no issue. Six months to a year raises questions. A year or more typically breaks continuous residence outright. Keep any trips short and return well before your ceremony date.

If you truly cannot attend, return your N-445 to your local USCIS office with a letter explaining why and requesting a new date. One reschedule with a good reason is usually fine.

What Happens at the Ceremony

Ceremonies are either judicial, administered by a federal or state court, or administrative, run by USCIS itself. Both produce the same legal result.⁶

At check-in, a USCIS officer reviews your N-445 responses, collects your green card, and collects any USCIS-issued travel documents.⁸ If something has changed since your interview, expect follow-up questions and possibly a delay.

The ceremony culminates in the group recitation of the oath, led by a judge or USCIS official. You raise your right hand and repeat the phrases with the other applicants. When the presiding official declares the group to be citizens, that is the exact moment your status changes.

After You Take the Oath

You leave the ceremony with a Certificate of Naturalization (Form N-550), the primary legal proof of your citizenship.⁹ Check the name, date of birth, and country of birth before you leave the venue. If anything is wrong, tell a USCIS officer on the spot. Correcting an error at the ceremony is much easier than filing Form N-570 for a replacement later.

A few practical steps follow in the days and weeks after:

Update your Social Security record. Wait at least ten days so federal databases can sync, then visit SSA with your Certificate of Naturalization.¹⁰
Apply for a U.S. passport through the Department of State using your Certificate of Naturalization as proof of citizenship.
Register to vote any time after the ceremony. Do not register before it; registering to vote as a non-citizen can jeopardize your immigration case.¹¹
Register with Selective Service if you are a male citizen between 18 and 25. This applies to newly naturalized citizens in that age range. If you are 26 or older, it is too late to register and you are not required to.¹²

Children Who Do Not Take the Oath

When you naturalize, some of your children become U.S. citizens automatically without taking the oath. Under INA Section 320, a child born outside the United States acquires citizenship by operation of law when all of the following are true at the same time, before the child turns 18:

At least one parent is a U.S. citizen, by birth or naturalization, including adoptive parents
The child is under 18
The child is a lawful permanent resident
The child resides in the United States in the legal and physical custody of the U.S. citizen parent

These conditions do not have to occur in any particular order. They just need to all be true simultaneously at some point before the 18th birthday.¹³ Joint custody satisfies the legal custody requirement.

Citizenship is automatic, but no certificate is issued automatically. To get formal proof, file Form N-600, Application for Certificate of Citizenship. Having that documentation on hand matters for school enrollment, passport applications, and anywhere else citizenship needs to be proven.
