Filing fees taken from USCIS Form G-1055 (the fee schedule), fee-schedule edition 05/29/26, last checked 2026-07-11. Fees change frequently — confirm your exact total on uscis.gov before filing.
Which edition of Form N-400 is current?
The current edition of Form N-400 is dated 01/20/25. The edition date is printed at the bottom of every page, and every page you file must come from that same edition — USCIS rejects filings made on a superseded edition. Download a fresh copy from uscis.gov right before you file and check the date again.
Two different dates — don't mix them up. 01/20/25 is Form N-400's own edition date, printed on the form. 05/29/26 is the edition of USCIS Form G-1055, the fee schedule the amounts above come from. They are two separate documents that change on separate timetables; only the 01/20/25 date is what USCIS checks on your form.
Who files Form N-400?
Green card holders who meet the residence, physical-presence, and good-moral-character requirements (generally after 5 years, or 3 years if married to a U.S. citizen).
Most common N-400 mistakes that cause rejections
USCIS rejects or issues a Request for Evidence on filings every day for small, fixable errors. For N-400, the ones we see most often are:
- Miscalculating continuous residence or physical presence, or omitting trips outside the U.S.
- Filing under the wrong basis (3-year vs. 5-year rule).
- Incomplete disclosure of tax, selective-service, or criminal history questions.
- Leaving required fields blank instead of answering every item.

How to file Form N-400 without getting rejected
- Use the current edition. USCIS rejects outdated editions — check the date printed at the bottom of the form (it should read 01/20/25) against uscis.gov.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 by hand. Only a handwritten ink signature — or a scan, photocopy, or fax of one — is valid on a paper N-400. A typed name, a cursive or script font, a stamp, or e-signature software output (such as DocuSign) is not. Electronic signatures count only when captured through a USCIS online account during online filing. Under the DHS signature rule effective 07/10/2026, an invalid signature on a paper filing can be denied — USCIS keeps the filing fee and there is no opportunity to cure — not merely rejected.
- 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.

What happens if my N-400 is rejected?
USCIS returns rejected forms without processing them, and filing fees are generally non-refundable — so you lose time and may have to pay again. Most rejections come from small, avoidable errors, which is why a pre-filing review is worth it.
