Additional Information for Completing Your Form:
If you submit Form N-426 on paper: Be sure to sign the form at Part 4, Item Number 4., Requestor’s Signature. The fillable version of Form N-426 now includes “Don’t forget to sign!” messages and an arrow pointing to the signature box as reminders for when you print the completed form for mailing. USCIS rejects any unsigned Form N-426. Having to return it to you for a signature will delay processing of your request.
Please read the instructions carefully. If relevant, please see M-599, Naturalization Information for Military Personnel
If you are currently serving in the U.S. armed forces, you must submit a signed and certified Form N-426 with your Form N-400, Application for Naturalization. Your Form N-426 must be certified by your commanding officer or other individual authorized to certify the form. NOTE: Recruiters are not authorized to certify Form N-426.
If you previously served in the U.S. armed forces, you must submit a copy of Form DD214, Certificate of Release or Discharge from Active Duty, or NGB Form 22, National Guard Report of Separation and Record of Service, for any periods of service you have completed. You may submit an uncertified Form N-426 as long as the DD214 or NGB 22 cover all applicable periods of service and list the type of separation and character of service.
