You just took the Oath of Allegiance and received your Certificate of Naturalization. Congratulations. But the ceremony is only the beginning of a long to-do list. Your green card was collected, you're holding a single piece of paper as proof of citizenship, and you probably have questions: Do I need a passport right away? How do I update Social Security? Can I travel internationally this week?
This guide covers everything you need to do after the oath ceremony, organized by when to do each step. Whether you became a citizen through the standard 5-year path or through the 3-year marriage-based route, the post-ceremony steps are the same. And if you filed your N-400 application, you already know we break things down step by step.
At the ceremony: 3 things to do before you leave
Before you walk out of that ceremony, take care of these three things. They're easy to overlook in the excitement, but skipping them can cost you hundreds of dollars and months of waiting.
1. Check your certificate for errors. Look at every detail on your Certificate of Naturalization (Form N-550): your full name, date of birth, country of former nationality, A-Number, and the photo. If anything is wrong, tell the USCIS officer immediately. Corrections due to USCIS clerical error are free. If you need a replacement certificate for reasons that require a fee, you'll generally use Form N-565, which costs $505 online or $555 by mail. Processing times vary—check the USCIS Processing Times tool for the current estimate (USCIS Form N-565).
2. Sign the certificate in black ink where indicated. This is required before you can use it for any application.
3. Pick up a voter registration form. Voter registration is not automatic after naturalization, so grab one while you're there.
Day 1: protect your naturalization certificate
Your Certificate of Naturalization is your only proof of citizenship until you get a U.S. passport. Protect it.
Make copies immediately. At least two paper photocopies and a digital scan saved to cloud storage or an encrypted drive. You'll need copies for your passport application, Social Security visit, and DMV appointment.
Never laminate it. Laminating can damage or obscure security features and may cause problems when someone needs to examine the original. If you need a replacement certificate for reasons that require a fee, Form N-565 costs $505 online or $555 by mail (USCIS Policy Manual, Vol. 12, Part K, Ch. 4).
Store the original safely in a fireproof safe or safety deposit box. Never carry the original. Use a photocopy for everyday purposes.
Week 1: apply for your U.S. passport
This is your top priority. Once you're a U.S. citizen, you are legally required to use a U.S. passport to enter and leave the United States (INA §215(b)). Your naturalization certificate is not a travel document and won't get you through airport security for an international flight.
How to apply: In person using Form DS-11 at a passport acceptance facility (most post offices and county clerk offices). Do not sign the form until the acceptance agent tells you to.
What to bring: Completed Form DS-11 (unsigned), original Certificate of Naturalization, a valid photo ID plus a front/back photocopy, one recent color passport photo (2x2 inches), and payment.
Current passport fees (2026):
| Document | Application Fee | Execution Fee | Total |
|---|---|---|---|
| Passport Book (adult) | $130 | $35 | $165 |
| Passport Card only | $30 | $35 | $65 |
| Both Book + Card | $160 | $35 | $195 |
| Expedited processing | +$60 | — | +$60 |
| 1-2 day delivery | +$22.05 | — | +$22.05 |
(State Department Passport Fees)
Processing times: Routine is 4 to 6 weeks (not including mailing time). Expedited is 2 to 3 weeks (+$60) (State Department Processing Times). For urgent international travel within 14 calendar days, you can apply at a passport agency or center by appointment (State Department).
Warning: Your supporting documents (including citizenship evidence) may be returned separately via USPS First Class Mail, and you may receive multiple mailings. Make sure you have copies before submitting the original.

After 10 business days: update Social Security
This step used to be simple. It's not anymore.
What changed in 2025: In 2025, multiple reports indicated SSA temporarily paused parts of its Enumeration Beyond Entry (EBE) process for some case types, but SSA has not posted a clear public notice on its EBE webpage about a pause for N-400-based updates. If you requested an SSN card update through your N-400 and don't receive it, SSA's EBE guidance says to contact a Social Security office if you have not received the replacement card within 14 days after receiving your Certificate of Naturalization.
Why wait 10 days: USCIS guidance says new citizens generally need to wait at least 10 days after the ceremony to update SSA records. If you go too early, SSA may not be able to verify your updated status yet and may ask you to come back.
What to bring: Completed Form SS-5, original Certificate of Naturalization or U.S. passport, and a valid photo ID. The update is free. Timing for when you receive your updated Social Security card can vary.
Why it matters: Your previous card likely says "VALID FOR WORK ONLY WITH DHS AUTHORIZATION." The updated card removes that restriction, which matters for E-Verify employment checks and Social Security benefits eligibility.
Passport first or Social Security first? Get your passport first. The passport application requires your original certificate, and you'll be without it for weeks. The 10-business-day SSA waiting period gives you time to submit your passport application first.
Register to vote
You're now eligible to vote, but registration is not automatic. You need to actively sign up through one of four methods: at the oath ceremony (if forms were available), online at vote.gov, by mail using the National Mail Voter Registration Form, or in person at your state or local election office.
Warning: Never register to vote before your naturalization is complete. Non-citizen voter registration is a federal crime and can result in removal proceedings and permanent bars to future immigration benefits.
Update your driver's license and get REAL ID
REAL ID enforcement went into effect May 7, 2025. You need a REAL ID-compliant license or another acceptable ID (like a U.S. passport) to board domestic flights. As of February 1, 2026, travelers age 18 or older who do not have acceptable ID can pay a $45 TSA ConfirmID fee so TSA can attempt to verify their identity; it's optional and not guaranteed (TSA ConfirmID).
Visit your state DMV with your Certificate of Naturalization, proof of Social Security Number, and two proofs of state residency to update your license.
Important: REAL ID does not prove citizenship. It's issued to both citizens and non-citizens. Only a U.S. passport or naturalization certificate proves citizenship (USA.gov REAL ID).
Sponsor family members and document your children
As a citizen, you can now petition for immediate relatives (spouse, unmarried children under 21, parents if you're 21+) with no visa caps or waiting lists using Form I-130. You also gain access to preference categories for married children and siblings.
Important: If you had a pending I-130 filed as a permanent resident, USCIS does not automatically upgrade it to the citizen category. You must request the upgrade from the National Visa Center or USCIS.
For your children: Kids under 18 with green cards generally derive citizenship automatically when you naturalize (INA §320). But they still need proof. A U.S. passport typically costs $135 for children under 16 when applying in person (a $100 application fee + $35 acceptance fee). A Certificate of Citizenship via Form N-600 costs $1,335 if filed online or $1,385 if filed by paper (and N-600 online filing is not available in some situations, including fee waiver requests and certain applicants outside the U.S.).
Steps most guides skip
Notify your employer. No legal requirement to update your I-9 if your green card was still valid, and employers cannot demand to see your naturalization certificate specifically (DOJ IER). But consider updating voluntarily, especially if your employer uses E-Verify.
Selective Service (males 18 to 25). If you are required to register, the Selective Service System says immigrants must register within 30 days after their 18th birthday or within 30 days after entry to the United States (if they are between 18 and 25).
Global Entry / TSA PreCheck. Global Entry ($120 for 5 years) includes TSA PreCheck and requires a U.S. passport. Apply after your passport arrives (CBP Global Entry).
Federal jobs. U.S. citizenship is now required for most competitive service federal jobs and all security clearance levels. Naturalized citizens are treated the same as birth citizens (USAJobs).
Jury duty. You're now eligible and required to serve when called. Jury pools are drawn from voter rolls and DMV records.

10 common mistakes new citizens make
- Not checking the certificate for errors at the ceremony. Free to fix on the spot, $505 to $555 later.
- Laminating the certificate. Can void the document and require a costly replacement.
- Traveling internationally without a U.S. passport. Your certificate is not a travel document.
- Delaying the passport application. Processing takes 4 to 10 weeks. Apply in Week 1.
- Assuming Social Security updates automatically. The EBE program was paused in March 2025. You must visit SSA in person.
- Assuming voter registration is automatic. It's not. You must actively register.
- Carrying the original certificate everywhere. Carry a photocopy. Store the original securely.
- Not understanding dual citizenship. The U.S. doesn't require you to give up your other citizenship. Your home country's laws determine whether you lose theirs.
- Not documenting children's citizenship. Children may derive citizenship automatically, but they still need proof (passport or N-600).
- Ignoring Selective Service (males 18 to 25). Failure to register can block federal jobs and student aid for decades.
