In short

  • Protect your Certificate of Naturalization. It is official proof of your citizenship. If you lose it, you can replace it with Form N-565.
  • Passport: your first U.S. passport is a new passport, so you apply in person with Form DS-11, your original certificate and a photocopy.
  • Social Security: update your record so it shows you are a citizen. USCIS says to wait at least 10 days after the ceremony.
  • Vote: you must register before you can vote. Start at vote.gov.

Congratulations! You are now a U.S. citizen. A few simple tasks in the next weeks will save you problems later. Here is a checklist with the official sources.

1. Protect your certificate

Your Certificate of Naturalization proves that you are a U.S. citizen. Keep it in a safe place at home. You will need the original to apply for your passport. If you lose it, file Form N-565, Application for Replacement Naturalization/Citizenship Document. While you wait, a U.S. passport can serve as proof of citizenship.

2. Apply for your U.S. passport, step by step

A U.S. passport is also official proof of citizenship. Because this is your first one, you must apply in person. It cannot be done online or by mail.

  1. Fill out Form DS-11. Do not sign it until the official at your appointment tells you to.
  2. Bring your original Certificate of Naturalization and a photocopy of it.
  3. Bring an acceptable photo ID and a photocopy of the front and back.
  4. Bring a passport photo and pay the passport fee.
  5. Go to a passport acceptance facility. Some need an appointment.
  6. Wait before you travel. USCIS says to allow enough time between the ceremony and any trip to get your passport.

You can also apply for a passport for a child under 18 who became a citizen automatically through your naturalization.

3. Update your Social Security record

Your Social Security record should show that you are a citizen. If it does not, the information your employer gets through E-Verify may be affected. USCIS says new citizens generally need to wait at least 10 days after the ceremony. You can submit Form SS-5, Application for a Social Security Card, by mail or in person at a Social Security office. For questions, call the Social Security Administration at 1-800-772-1213 or visit ssa.gov.

4. Register to vote

Voting is a right and a responsibility of citizenship. You receive a voter registration application after you take the Oath, and sometimes you can register right after the ceremony. If not, go to vote.gov, choose your state and follow its instructions: online, by mail or in person. You can also register when you get or renew your driver's license. Documents vary by state; in most cases you need a driver's license or a state ID.

When you vote, you will choose leaders like the ones you studied for the test. Remember the questions about your senators, your representative and your governor? See answers that depend on your state.

5. Other things you can do now

  • Your children. A child who was a permanent resident under 18 on the day you naturalized may have become a citizen automatically. Form N-600 gives them a Certificate of Citizenship.
  • Your family. As a citizen, you may petition for certain relatives to become permanent residents.
  • Your driver's license. If your name or address changed, update it with your state's motor vehicle agency.

Frequently asked questions

Do I need a passport if I have my certificate?

Both are official proof of citizenship. You need a passport to travel to most countries outside the United States.

Can I vote right after the ceremony?

You can vote once you are registered, and registration rules and deadlines depend on your state. Check vote.gov.

Should I carry my certificate with me?

It is better to keep it in a safe place and carry another ID. You need the original for your passport application.

What if there is an error on my certificate?

USCIS asks you to review the certificate and tell USCIS about any error before you leave the ceremony. If you find an error later, contact USCIS.
