Oath Ceremony Guide 2026: What Happens and What to Bring

What the Oath Ceremony Is

The naturalization ceremony is where the process ends and citizenship begins. You are not a US citizen until you take the Oath of Allegiance at a ceremony. Until that moment, even after USCIS approves your application, you remain a lawful permanent resident, and you keep the rights and limits of that status.

There are two kinds of ceremony. In a judicial ceremony a court administers the oath, and the court can also grant a legal name change. In an administrative ceremony USCIS administers the oath, often in a group setting at a field office or a special venue. Both end the same way: you surrender your green card, take the oath, and receive your Certificate of Naturalization.

The ceremony is deliberately formal. USCIS asks that you dress in proper attire to respect the dignity of the event. Family members are often welcome, and some offices combine the ceremony with a welcome programme explaining voting, passports, and Social Security updates. Plan for one to two hours including check-in, even though the oath itself takes only a few minutes.

Same-Day vs Scheduled Ceremonies

Some field offices offer a same-day oath immediately after your interview if your case is approved and space allows. If a ceremony is not available that day, USCIS mails you a notice with the date, time, and location using Form N-445, Notice of Naturalization Oath Ceremony. USCIS aims to notify you of a scheduled ceremony well in advance so you can arrange time off and travel.

Either path is normal, and neither is a sign of a problem. A same-day ceremony simply compresses the timeline. If you are told a ceremony is not available, expect the notice by mail, and watch your USCIS online account and mailing address so you do not miss it. If you plan to travel, remember that you cannot become a citizen while abroad; the oath must be taken in person in the United States.

Form N-445 and the Questions You Answer

Form N-445 is not a form you file in advance. It is the ceremony notice, and you complete the questionnaire on it on the day of the ceremony. The critical point is that the questions cover only events since your interview, not your entire history. If nothing changed, you answer no to each item.

The questionnaire asks whether, since your interview, you:

• married, or were widowed, separated, or divorced;
• traveled outside the United States;
• knowingly committed any crime or offense, or were arrested, cited, charged, indicted, convicted, fined, or imprisoned, including traffic violations;
• joined, became associated with, or connected to any organisation, including a Communist or totalitarian party or a terrorist group;
• deserted from, claimed exemption from, or were separated or discharged from military service;
• changed your willingness to bear arms, perform non-combatant service, or perform work of national importance under civilian direction;
• practised polygamy, received income from illegal gambling, been involved in prostitution, helped anyone enter the US illegally, trafficked controlled substances, given false testimony, or been a habitual drunkard.

If you answer yes to any item, bring documents that support the answer, such as a marriage certificate, a divorce decree, or travel records. Answer everything truthfully; the officer reviews the questionnaire at check-in, and a material change can pause or complicate the oath.

What to Bring and What Happens at Check-In

Bring the completed N-445, the documents it lists, and your green card. USCIS collects your Permanent Resident Card at check-in because you will receive the Certificate of Naturalization after the oath. The requirement to surrender the card is waived only in narrow cases, such as proven loss or certain military service.

At check-in a USCIS officer reviews your N-445 answers and collects your card. You then take your seat for the ceremony, stand for the Oath of Allegiance when instructed, and receive your Certificate of Naturalization. Before you leave the room, read the certificate line by line: every name, date of birth, and spelling. Correcting it later is slower and costs a filing fee.

Travel After the Interview but Before the Oath

You may generally travel between your interview and your ceremony, but the trip appears on Form N-445, where you must answer yes to the travel question and bring travel documents. More importantly, long absences can still affect the continuous-residence and physical-presence requirements, and you must be physically present in the United States to take the oath.

Keep any post-interview travel short if you can, keep evidence of your US ties, and make sure someone checks your mail for the ceremony notice. If a scheduled ceremony conflicts with unavoidable travel, do not simply skip it; follow the rescheduling steps below. A trip taken to avoid a ceremony is treated far less kindly than a documented emergency.

Changing Your Name at the Oath

A legal name change at naturalization is requested on your Form N-400, not at the ceremony desk. In Part 2, Item 3 you answer whether you want to change your name and provide the new name. A court can grant that change when it administers the oath at a judicial ceremony, and the change is not final until you are naturalized by the court; the Certificate of Naturalization is then issued in the new name as ordered.

If your legal name already changed through marriage, divorce, or a court order, you do not request a change; you just provide the supporting document. If you change your name after you naturalise, you must file Form N-565 to replace your certificate, which currently costs $555 on paper or $505 online. Decide on the name you want before you file, because changing course later is costly.

The Certificate of Naturalization

USCIS issues your Certificate of Naturalization after you take the Oath of Allegiance, generally in person at the ceremony. It is official proof that you are a US citizen, and it is the document you will use to apply for a passport, register to vote, and update your Social Security record. USCIS will not issue the certificate before you surrender your green card unless loss is documented.

Check the certificate carefully before leaving: a misspelled name, a wrong date, or an incorrect country of former nationality is far easier to fix on the spot than months later. If you lose your certificate, request a replacement with Form N-565. Note that USCIS does not mail Certificates of Naturalization outside the United States except in limited military cases, so plan your travel around receiving it.

Applying for a Passport After the Oath

Once you hold your Certificate of Naturalization you can apply for a US passport, and many new citizens do it the same week. The certificate proves your citizenship; the passport lets you travel and serves as strong identity and citizenship evidence. You can apply for a passport book, a passport card, or both, and applying together saves the $35 execution fee on one document.

As a first-time adult applicant using Form DS-11, a passport book costs $165, a passport card costs $65, and both together cost $195. Allow enough time between the ceremony and any planned trip to receive the passport, or request expedited service. Our passport renewal guide and DS-11 application guide walk through the forms, and the passport fee calculator totals the cost.

Delays, Rescheduling, and No-Shows

If you cannot attend your scheduled ceremony, return the N-445 to your local USCIS office with a letter requesting a new date and explaining why. Keep proof that you sent it. Failing to appear more than once may lead to denial of your application, so treat the notice as a hard appointment.

Delays happen for ordinary reasons: a crowded ceremony schedule, a missing document, or a change you reported on the N-445 that needs review. Respond quickly to any request. If USCIS waived the oath requirement for a documented medical disability, it issues the certificate in person or by certified mail to you or your representative, and you do not attend a ceremony at all. In every other case, the certificate follows the oath.
