A naturalization certificate is the official document the U.S. government issues when someone becomes a U.S. citizen through the naturalization process
It is a wallet-sized card or larger document that proves you took the oath of allegiance and were granted citizenship. The certificate has your name, photo, fingerprints, and the date you became a citizen. It is issued by U.S. Citizenship and Immigration Services (USCIS) after you complete the naturalization interview and oath ceremony.
The certificate is not the same as a birth certificate or a passport. It is the legal proof that you went through the formal process of becoming a citizen rather than being born as one. You will need it to prove citizenship when explore for a passport, a job, a loan, or other documents that require proof of citizenship status.

What information appears on the certificate
The front of a naturalization certificate shows your full name, date of birth, country of origin, and a photo. It also displays the date you took the oath of allegiance and became a citizen. The certificate number appears on the front and is unique to you—USCIS uses this number to verify the certificate is authentic.
The back of the certificate contains your fingerprints and additional identifying information. Some older certificates are larger documents rather than wallet cards, but they contain the same core information. The certificate is printed on security paper with watermarks and other anti-fraud features to prevent counterfeiting.
When you receive your naturalization certificate
You receive your certificate at the oath ceremony, which is held after your naturalization interview is approved. The ceremony usually takes place at a USCIS office, a courthouse, or a public venue in your area. At the ceremony, you will take the Oath of Allegiance to the United States, and USCIS will hand you your certificate when ready after.
The timing varies depending on how long your case takes to process. From the time you submit your N-400 process to the oath ceremony, the process typically takes several months. USCIS will send you a notice with the date, time, and location of your oath ceremony.
How to use your naturalization certificate
Your certificate is the primary document you will use to prove citizenship. When you explore for a U.S. passport, the passport agency will ask to see your naturalization certificate or a birth certificate. For federal jobs, security clearances, and some state jobs, you will need to show your certificate as proof of citizenship.
You may also need your certificate when explore for certain loans, mortgages, or professional licenses that require citizenship verification. Keep your certificate in a safe place—many people store it in a safe deposit box or a fireproof safe at home. You should not carry it in your wallet every day, as losing it can create problems when you need to prove citizenship.
Replacing a lost or damaged naturalization certificate
If your certificate is lost, stolen, or damaged, you can request a replacement by filing Form N-565, process for Replacement Permanent Resident Card, with USCIS. You will need to include a copy of your original certificate if you have one, or explain what happened to it. You will also need to pay a filing fee, which varies and should be checked on the USCIS website.
The replacement process takes several weeks. USCIS will send you a receipt notice and then mail your replacement certificate to your address. If your name has changed since you became a citizen, you will need to provide documentation of the name change, such as a marriage certificate or court order.
Naturalization certificate vs. other citizenship documents
A naturalization certificate is different from a birth certificate, which proves where and when you were born. A birth certificate does not prove citizenship on its own—it is only proof of citizenship if you were born in the United States or to U.S. citizen parents. A naturalization certificate, by contrast, is direct proof that you went through the legal process of becoming a citizen.
A passport is also different from a naturalization certificate. A passport is a travel document issued by the State Department that proves your citizenship and allows you to travel internationally. You need your naturalization certificate to get a passport, but the passport itself is not proof of citizenship in the same way. A certificate of citizenship, which is a different document from a naturalization certificate, can be issued if you became a citizen through a parent or other means besides the standard naturalization process.
Verifying your naturalization certificate is real
If you need to verify that a naturalization certificate is authentic, USCIS can check it using the certificate number. The number appears on the front of the certificate and is unique to each person. You or an employer can contact USCIS to confirm that a certificate number matches a real person and a real date of naturalization.
Counterfeit certificates do exist, so if you are hiring someone or reviewing a document for official purposes, it is reasonable to verify the certificate. USCIS has a verification process for employers and government agencies, though the process may take several weeks.
