If you already qualify as a U.S citizen, but lack official proof, Form N-600 may be the missing piece. This guide breaks down everything you need to know about Form N-600, including eligibility, costs, processing times, required documents, and what to expect after filing.
What Is Form N-600?
Form N-600, officially called the Application for Certificate of Citizenship, is used to request proof that you are already a U.S. citizen. It does not grant citizenship; instead, it provides formal documentation of citizenship status.
You typically use this form if:
You were born outside the U.S. to U.S. citizen parent(s), or
You automatically became a citizen before age 18 through a parent.
The result is a Certificate of Citizenship, which can be used for things like applying for a U.S. passport or proving eligibility for benefits.
Who Is Eligible for Form N-600?
You may qualify to file Form N-600 if you:
Were born abroad to at least one U.S. citizen parent, or
Derived citizenship automatically after birth (for example, when a parent naturalized before you turned 18), and
Met all legal requirements at the time citizenship was acquired.
A parent or legal guardian can also file on behalf of a minor child.
Who Cannot File Form N-600?
Not everyone’s needs, or is allowed,to file Form N-600. You generally should not file if:
You were born in the United States (your birth certificate is proof of citizenship)
You became a citizen through naturalization (you receive a Certificate of Naturalization instead)
You are not yet a U.S. citizen
In short, Form N-600 is only for people who are already citizens but need documentation.
Form N-600 Fees and Costs
As of 2025-2026, the filing fee is approximately:
$1,385 (paper filing)
Around $1,335 if filed online in some cases.
Important notes:
Fees are non-refundable, even if your application is denied.
Some applicants (such as U.S.military members) may qualify for fee exemptions.
Legal assistance (optional) can add $500-$2000+ depending on complexity.
Form N-600 processing time
Processing times vary widely depending on workload and location. Typical estimates range from 3 ½ months to 22 months on average. Some cases may move faster, especially if documentation is complete, while others take longer if additional evidence is requested.
Form N-600 Required Documents
You must submit evidence proving your citizenship claim. Common documents include:
Your birth certificate
Proof of your parent’s U.S.citizenship (passport, naturalization certificate, or birth certificate)
Evidence of your relationship to your parent(e.g., marriage certificate if applicable)
Proof of legal custody or residency (for derivative citizenship cases)
Passport-style photos (if applying from outside the U.S.)
The exact documents depend on your situation, so carefully review the official instructions.
