Check your Form N-600 for errors before you file

Requests a Certificate of Citizenship for someone who is already a U.S. citizen by birth abroad or automatically through a parent. A single missed signature or blank field gets the whole package returned — and the $1,385 filing fee is generally non-refundable. Here is exactly what to verify on your completed N-600 before it goes to USCIS.

How do I check my N-600 for errors?

1. Confirm you have the current edition

USCIS accepts only the current edition of N-600 — filing a superseded version is an automatic rejection. The current edition is dated 01/20/25; the date is printed at the bottom of every page. All pages must come from the same edition. Download a fresh copy from uscis.gov right before you file.

2. Verify every signature block

Unsigned or wrongly-signed forms are rejected outright — stamped or typewritten names are not accepted. N-600 has 4 signature blocks to check:

3. Make sure no required section is incomplete

Leaving required fields blank (instead of writing “N/A” or “None”) is one of USCIS's most common rejection reasons. On N-600, pay special attention to:

• Part 1, Items 1-2: Eligibility: indicate whether the CHILD or the PARENT/LEGAL GUARDIAN is filing, and select EXACTLY ONE parent-child relationship box — USCIS WILL REJECT the N-600 if this is not selected
• Part 2, Items 1: Current legal name (as on birth certificate or legal name change)
• Part 2, Items 2: Name exactly as it appears on the Permanent Resident Card (if different)
• Part 2, Items 3: Other names used since birth (overflow goes in Part 11)
• Part 2, Items 4: U.S. Social Security Number (or N/A)
• Part 2, Items 6: Date of birth (mm/dd/yyyy)
• Part 3, Items 1-6: U.S. citizen parent’s information and citizenship evidence (acquisition vs derivation basis)

4. Check every date — format and consistency

Dates must be written mm/dd/yyyy and must agree with your supporting documents and any other forms in the package. The date fields that most often cause problems on N-600:

• Child’s DOB vs parent’s naturalization date vs LPR date — Automatic citizenship under INA 320 depends on the ORDER of these dates — inconsistencies are the core N-600 problem.
• Dates that must match the birth certificate and green card exactly — Mismatches with supporting records trigger RFEs.

5. Re-check the known N-600 rejection triggers

From USCIS's own instructions and rejection criteria, these are the specific triggers to rule out on N-600:

• Part 1 relationship/filer box not selected — explicit USCIS rejection trigger
• Application not signed, or signed by the wrong person (child vs parent/guardian rules)
• Wrong fee (check current G-1055 — N-600 has no fee for military filers)
• Claiming the wrong basis (acquisition at birth vs derivation through naturalization)
• Missing evidence of the parent’s U.S. citizenship or the parent-child relationship
