Apostille of a U.S. Naturalization Certificate

A Certificate of Naturalization is an official federal record issued by U.S. Citizenship and Immigration Services confirming that an individual became a United States citizen through naturalization.

Naturalization records may be requested for use abroad in matters involving dual citizenship, inheritance, marriage, property, immigration, or other legal and civil-status proceedings.

Because these are federal records, authentication is handled through the U.S. Department of State rather than a state Secretary of State.

Frequently Asked Questions

Naturalization Certificate Apostille FAQs

Is a Certificate of Naturalization a federal document? +
Yes. Certificates of Naturalization are issued by U.S. Citizenship and Immigration Services and follow the federal authentication process rather than a state apostille process.
Who issues the apostille for a Naturalization Certificate? +
Eligible federal naturalization records are authenticated through the U.S. Department of State Office of Authentications.
Should I send my original Naturalization Certificate? +
Because a Naturalization Certificate is an important identity and citizenship record, many applicants prefer to obtain a USCIS-certified true copy when an authenticated copy is acceptable. We recommend confirming the receiving authority’s requirements before submitting the original certificate.
Can I use a regular photocopy? +
A plain photocopy generally does not carry the federal certification needed for authentication. USCIS has a procedure for issuing certified true copies of Naturalization and Citizenship Certificates for use abroad.
What about historical naturalization records? +
Historical records may be held by the National Archives or another government custodian. A certified copy from the appropriate custodian may be apostilled through the U.S. Department of State.
Can you help me obtain a certified copy? +
We can review the record type and explain which issuing authority generally provides the appropriate certified copy. Availability and procedures depend on whether the record is held by USCIS, the National Archives, or another custodian.
Does the destination country matter? +
Yes. The receiving authority may have its own requirements regarding original documents, certified copies, translations, apostilles, or additional legalization. Those requirements should be confirmed before processing.
