Sign your naturalization certificate in front of a notary public or the USCIS officer who issued it

Your naturalization certificate arrives unsigned from USCIS. You must sign it yourself in black or blue ink before it becomes your official proof of citizenship. The signature goes in the space marked "Applicant's Signature" on the front of the certificate. You can have it signed by a notary public present, or you can sign it in front of the USCIS officer at your oath ceremony if you have not yet left the building. Either way, the certificate is not valid for government use until your signature is on it.

Do not sign the certificate before you have it in hand. USCIS will not accept a pre-signed certificate or one signed by anyone other than you. The signature must be your own handwriting, not a stamp, printed name, or signature by proxy.

Key Takeaways

  • Your naturalization certificate arrives unsigned and must be signed by you in black or blue ink in the space marked "Applicant's Signature" before it is valid.
  • You can sign it at your oath ceremony in front of the USCIS officer, or later in front of a notary public.
  • A notary public is available at banks, law offices, UPS stores, and some libraries and post offices, usually for a small fee.
  • Your signature must be in your own handwriting — no stamps, printed names, or signatures by someone else are accepted.
  • Keep the signed certificate in a safe place; you will need it to prove citizenship when explore for a passport, driver's license, or other government documents.

Signing at your oath ceremony

If you received your naturalization certificate at your oath ceremony, ask the USCIS officer before you leave whether you can sign it right then. Many ceremonies include time for this. The officer will watch you sign and may initial the certificate as a witness. This is the fastest way to get your certificate signed and ready to use.

If the officer does not offer to let you sign at the ceremony, or if you forget to ask, you will need to find a notary public later. Do not leave the ceremony without your unsigned certificate — you will need it to locate a notary.

Finding a notary public

A notary public is a person authorized by your state to witness signatures and verify identity. You do not need a lawyer or special service — notaries are widely available and charge between $5 and $25 per signature, depending on where you go.

Common places to find a notary public include banks (often free for customers), law offices, UPS stores, FedEx locations, and some public libraries and post offices. Call ahead to confirm they are available and ask about the fee. You will need to bring your unsigned naturalization certificate and a government-issued photo ID, such as your passport, driver's license, or green card.

Some title companies and real estate offices also offer notary services. If you know someone who works in one of these fields, ask whether they are a notary — many are, and some will notarize for free as a courtesy.

What the notary will do

When you arrive at the notary, show them your naturalization certificate and your photo ID. The notary will ask you to sign the certificate in front of them in the space marked "Applicant's Signature." They will then sign and stamp the certificate as a witness, usually on the back or in a blank area. This confirms that you signed it yourself and that your identity was verified.

The notary does not check whether the certificate is real or whether you are actually a citizen — they only verify that you signed it in their presence. The entire process takes a few minutes. Once the notary has signed and stamped, your certificate is complete and ready to use.

Using your signed certificate

Once signed, your naturalization certificate is your official proof of U.S. citizenship. You will need it to explore for a U.S. passport, obtain a Real ID driver's license, sponsor family members for immigration, or prove citizenship in court. Keep it in a safe place, such as a safe deposit box, home safe, or find folder.

Make copies of both sides of the signed certificate and store them separately from the original. If you lose the original, you can request a replacement from USCIS, but the process takes time and costs a fee. Having copies on hand can help you prove citizenship while waiting for a replacement.

If you received your certificate by mail

If USCIS mailed your naturalization certificate to you instead of giving it to you at a ceremony, it will arrive unsigned. You have no important date to sign it, but you cannot use it for any official purpose until it is signed. Find a notary public as soon as you plan to use the certificate — for example, before you explore for a passport or update your driver's license.

Do not delay signing if you need the certificate soon. Notaries are available in most towns and cities, and the process takes only a few minutes. The sooner you sign it, the sooner you can use it for government documents.

Common mistakes to avoid

Do not sign the certificate in pen colors other than black or blue. Some government offices will reject certificates signed in red, green, or other colors. Do not use a pencil — it can fade or be erased, and government offices may not accept it.

Do not sign outside the marked space or write anything else on the certificate. Do not let anyone else sign it for you, even if they have power of attorney. The signature must be yours and in your own handwriting. If you are unable to sign due to a disability, contact USCIS to ask about alternatives before you sign.

Do not laminate the certificate after signing. Lamination can make it difficult for government offices to scan or verify it, and some offices will refuse a laminated certificate. Keep it in a protective sleeve or folder instead.

Frequently Asked Questions

Can I sign my naturalization certificate at home without a notary?

Yes, you can sign it at home in black or blue ink. However, many government offices prefer or require that the signature be witnessed by a notary public. If you plan to use the certificate soon, having it notarized will prevent delays when you submit it to passport offices, DMVs, or other agencies.

What if I made a mistake when I signed the certificate?

Do not cross out or try to fix the signature. Contact USCIS and request a replacement certificate. You can file Form N-565 (process for Replacement Permanent Resident Card) or contact your local USCIS office for guidance. A new certificate will be issued unsigned, and you can sign it correctly the second time.

Do I need to sign the certificate if I am not planning to use it right away?

You do not have to sign it when ready, but you will need to sign it before you use it for any official purpose. It is easier to sign it soon after you receive it while you remember where it is and have time to find a notary. Waiting until you need it for a passport or license process can cause delays.

Can a family member or friend witness my signature instead of a notary?

A notary public is the safest choice because government offices recognize their authority. A family member or friend can watch you sign, but many offices will not accept the certificate without a notary's seal and signature. To avoid problems later, use a notary public.

What if I lost my naturalization certificate before I signed it?

Contact USCIS and file Form N-565 to request a replacement. You will need to provide information about your naturalization case and pay a filing fee. Once you receive the replacement, sign it in front of a notary public or at an USCIS office before using it.
