Who files Form N-600?
People who acquired or derived U.S. citizenship through a U.S. citizen parent and want documentation of it.
Most common N-600 mistakes that cause rejections
USCIS rejects or issues a Request for Evidence on filings every day for small, fixable errors. For N-600, the ones we see most often are:
- Claiming the wrong basis for acquired vs. derived citizenship.
- Missing evidence of the parent's citizenship or the qualifying relationship.
- Errors in dates and places that must match the supporting records.
- Signature missing or by the wrong person.

- Use the current edition. USCIS rejects outdated editions — check the date printed at the bottom of the form against uscis.gov.
- Answer every field. Write “N/A” or “None” instead of leaving anything blank — blanks are a leading rejection cause.
- Be consistent. Your name, A-Number, and dates must match exactly across every form and supporting document.
- Sign and date correctly. An unsigned or wrongly-signed form is rejected outright.
- Translate foreign documents. Include a complete certified English translation of anything not in English.
- Pay the exact fee. Use the fee calculator and confirm on uscis.gov — the wrong amount gets the package returned.
