1. What Should You Do If Your U.S. Citizenship Certificate Is Lost?
A missing certificate does not change citizenship status. First, identify the original document and determine whether an existing passport can satisfy the immediate need for proof.
Identify the Original Certificate
A Certificate of Naturalization documents citizenship granted through naturalization. A Certificate of Citizenship confirms citizenship acquired at birth or derived under federal law, generally through a U.S. citizen parent.
Form N-565 replaces eligible certificates previously issued by USCIS or the former Immigration and Naturalization Service (INS). Someone seeking a Certificate of Citizenship for the first time may need Form N-600 instead. Federal naturalization and citizenship procedures distinguish initial documentation from replacement.
Check Available Records and Discrepancies
Gather certificate copies, USCIS approval notices, passport records, and legal name-change documents. A photocopy may help identify the original issuance but generally cannot replace an official certificate.
Compare names and birth dates across records. Discrepancies may result from later legal changes, government errors, or information recorded during the original application. If USCIS approved a certificate that never arrived, check its delivery history before filing for a lost document.
2. How Do You Replace a Lost Citizenship Certificate with Form N-565?

Eligible applicants request replacement through Form N-565, Application for Replacement Naturalization/Citizenship Document. INA § 343 and 8 CFR § 343a.1 address replacement, while additional regulations govern specific certificate corrections.
Prepare Form N-565 and Supporting Evidence
Applicants should explain when, where, and how the certificate was lost, stolen, or destroyed. Evidence varies according to the replacement reason and current USCIS instructions.
Relevant materials may include:
- Completed Form N-565 with accurate identifying information.
- A copy of the original certificate, if available.
- A statement or police report explaining the loss, as applicable.
- Marriage records or court orders supporting a requested legal name change.
A police report is not required in every loss case. Before filing, verify the current form edition, filing method, and fee. USCIS may request additional evidence, biometrics, or an interview.
Respond to Missing Records or USCIS Requests
If the certificate number is unavailable, do not guess. Previous USCIS notices and naturalization records may help establish the original issuance.
When USCIS issues a Request for Evidence (RFE), respond to the specific deficiency within the notice's deadline. Missing identification details may require additional records, while conflicting citizenship information may require examination of the original file.
Form N-565 replaces an existing document. It does not reopen the original naturalization law process or establish citizenship for the first time.
3. Can You Prove Citizenship While Waiting for a Replacement?
A qualifying U.S. passport may establish citizenship while Form N-565 remains pending. Acceptance depends on the receiving institution and its documentation requirements.
Compare Available Citizenship Evidence
Different documents serve different purposes when proving citizenship.
| Document | Evidentiary Role |
|---|---|
| Valid U.S. passport | Generally accepted proof of citizenship |
| Expired full-validity passport | May qualify as evidence for a passport application |
| Certificate photocopy | May support N-565 but does not replace the official certificate |
| USCIS receipt notice | Confirms filing, not citizenship |
| Prior passport records | May support a qualifying passport file search |
Valid U.S. passport
- Evidentiary RoleGenerally accepted proof of citizenship
Expired full-validity passport
- Evidentiary RoleMay qualify as evidence for a passport application
Certificate photocopy
- Evidentiary RoleMay support N-565 but does not replace the official certificate
USCIS receipt notice
- Evidentiary RoleConfirms filing, not citizenship
Prior passport records
- Evidentiary RoleMay support a qualifying passport file search
An expired passport does not satisfy every institution's requirements. A USCIS receipt notice also cannot serve as temporary citizenship documentation.
Consider a Passport File Search
The Department of State offers a file-search procedure for eligible passport applicants who previously received a U.S. passport or Consular Report of Birth Abroad (CRBA) but cannot submit it.
A qualifying search may establish citizenship evidence for a passport application. It does not replace a USCIS certificate. Applicants should check the applicable eligibility requirements and any search fee.
4. When Does Certificate Replacement Require Legal Review?
Straightforward replacement requests generally do not require an attorney. More complex issues arise when identity information conflicts, USCIS cannot verify the original issuance, or a requested correction is denied.
Determine Whether Certificate Information Can Be Corrected
Under 8 CFR § 338.5, USCIS generally cannot change a Certificate of Naturalization's date of birth merely because an applicant later disputes information affirmed during naturalization. USCIS clerical errors may qualify for correction.
A qualifying legal name change after naturalization may support a replacement certificate. Certificates of Citizenship have separate correction provisions, including certain documented date-of-birth changes.
Before applying, determine whether the discrepancy originated in the government record, resulted from certificate preparation, or followed a later legal change.
Review a Denied Replacement Application
USCIS may deny Form N-565 when evidence does not establish previous issuance, a requested correction is unsupported, or other eligibility requirements are unmet.
The denial notice should explain the decision and available review procedures. Depending on the circumstances, an administrative appeal or motion may be available under applicable filing deadlines.
When the original issuance cannot be verified, additional immigration records may be necessary. A citizenship law firm can review the denial, identify missing evidence, and assess whether replacement, correction, or another citizenship-related application is appropriate.
