After Naturalization: Your New-Citizen Checklist

Updated: October 30, 2026

After you take the oath, a few tasks make your new citizenship work in everyday life. The most important are: protect your Certificate of Naturalization, apply for a U.S. passport, update your Social Security record, and register to vote. If you have family abroad, you may now be able to sponsor more relatives, and faster. Here's the full checklist, roughly in the order most people do it.

1. Secure your Certificate of Naturalization

Your certificate is your main proof of citizenship until you have a passport.

Store it somewhere safe and dry, such as a fireproof document box
Don't laminate, fold or write on it
The certificate warns against copying it without lawful authority, so only copy it when you need to for an official purpose
If it's lost or damaged, replacing it with Form N-565 costs $555 on paper or $505 online (as of October 2026) and can take months

If you found an error on it after the ceremony, file Form N-565 to correct it. There's no fee if the error was USCIS's fault.

2. Apply for a U.S. passport

A U.S. passport is the most practical proof of citizenship. It also lets you travel and re-enter the United States as a citizen. As a first-time applicant, you apply in person at a passport acceptance facility, often a post office or county clerk's office, using Form DS-11.

Bring:

Your original Certificate of Naturalization, plus a photocopy. The original is returned to you, usually in a separate mailing.
A valid photo ID, such as a driver's license, plus a photocopy
One passport photo meeting State Department rules
Payment. As of October 2026, an adult passport book costs a $130 application fee paid to the State Department, plus a $35 acceptance fee paid to the facility. Check current fees at travel.state.gov.

If you have a trip planned, expedited service costs extra. Don't book international travel before you have your passport in hand. From now on, as a U.S. citizen, you must enter and leave the United States on a U.S. passport.

3. Update your Social Security record

The Social Security Administration needs to know you're a citizen. That affects things like E-Verify checks at work.

If you consented on your N-400 (Part 2, Social Security update), USCIS sends your information to SSA after your oath. You usually don't need to visit an office. You can check your record later through a my Social Security account.
If you didn't consent, contact SSA. Bring your Certificate of Naturalization or U.S. passport and your Social Security card. Wait a little while after the ceremony, since SSA's systems may need time to verify your citizenship.

If you changed your name at the ceremony, you'll need a new Social Security card with the new name.

4. Register to vote

As a citizen you can vote in federal, state and local elections. Registration rules and deadlines vary by state.

Register online, by mail or in person, depending on your state. vote.gov is the official federal starting point.
Some ceremonies have voter registration tables after the oath.
Many states let you register when you update your driver's license.

Registering to vote before your oath can cause serious immigration problems. If you registered or voted earlier as a non-citizen, get legal advice. After the oath, registering is your right. See rights and responsibilities of U.S. citizens.

5. Update your driver's license or state ID

Visit your DMV to update your status, which matters for REAL ID and for some state records. Bring your passport or naturalization certificate. If you changed your name, update it here too.

6. Tell your employer, if needed

You generally don't need to fill out a new Form I-9 just because you naturalized. But if you're in a job with citizenship requirements, such as certain government jobs or security clearances, tell HR and show your new documents.

7. Sponsor relatives

Citizens can petition for more relatives than green card holders, often with shorter waits:

Your spouse, unmarried children under 21, and parents (if you are at least 21) are "immediate relatives," with no annual visa cap
Adult or married children, and siblings (if you are at least 21), can be sponsored in the family preference categories
If you already filed a Form I-130 for a spouse or child as a green card holder, your naturalization usually upgrades that petition to the immediate relative or a different category. Inform USCIS or the National Visa Center.

Your children under 18 who have green cards and live with you may already have become citizens automatically. See citizenship for children and Form N-600.

8. Think about your other citizenship

Your former country may have rules about naturalizing elsewhere. Some let you keep dual citizenship, others require you to report it, and some end your citizenship automatically. Check with your country's embassy before using your old passport. See dual citizenship and the U.S..

9. Update other accounts

Banks and investment accounts, especially if they recorded you as a non-citizen
Insurance and benefit programs that recorded your immigration status
Professional licenses that require citizenship information
Selective Service: men under 26 who aren't registered yet must register
Your tax preparer: your residency status is unchanged, but note your new status

10. Know your new responsibilities

New citizens can be called for jury duty, should vote in elections, and must file taxes as citizens even when living abroad. The civics test you studied covers many of these duties.

Frequently asked questions

Can I travel abroad right after the ceremony?

Only if you have a valid passport you can use. You must enter the United States on a U.S. passport, and you no longer have a green card. Most people wait until their U.S. passport arrives.

Do I need to apply for a new Social Security number?

No. You keep the same Social Security number. Only your citizenship status, and your name if it changed, needs to be updated.

How soon can I vote?

As soon as you're registered and your state's registration deadline for an election hasn't passed. Some states allow registration on Election Day. Check your state's rules.

Do I need to keep my old green card?

No. You hand it in at the oath ceremony. Your Certificate of Naturalization and U.S. passport replace it as proof of status.
