Tips for Filing Form N-400, Application for Naturalization

On February 4, 2014, USCIS published a revised Form N-400 (Rev. 9/13/13), Application for Naturalization. When you fill out your Form N-400, you must complete every section and answer every question as completely as you can. Also, please note that, as of May 5, 2014, USCIS will only accept the Form N-400 that has a revision date of 9/13/13.  The revision date is printed on the lower left corner of the form.

To help you understand the naturalization process, USCIS developed A Guide to Naturalization (M-476). This publication provides information on eligibility requirements and naturalization procedures. For more information on naturalization eligibility requirements, including USCIS policies, please check out our USCIS Policy Manual.

To ensure you submit a complete and correct N-400, please follow these filing tips.

General Instructions

• Read the Form N-400 Instructions carefully.
• Use the revised version of Form N-400 which is posted on our website at www.uscis.gov/n-400. If you can, fill out your Form N-400 on a computer.  When you use a computer to complete this form, the data you type is stored in the barcode at the bottom of each page. This improves accuracy and efficiency of processing.
• We will accept N-400 forms (Rev. 9/13/13) that do not have the barcode on the bottom.
• Do not damage or write on the 2D barcode located at the bottom of each page.
• If you can’t use a computer to fill out this form, that’s okay.  We still accept hand-written applications.  Use a black pen when you fill out the form by hand.
• Do not highlight or cross out text on the form or write outside the blank spaces provided for your answers. Answer every question.  If a question does not apply to you, answer with “N/A.” If your answer to a question is “none,” answer with “none.”
• If you cannot answer a question because you do not have the information or you don’t know the answer, include a written explanation on a separate piece of paper.
• If you do not have an Alien Registration Number (A-Number), leave that space blank.
• Enter dates in month/day/year format (like this MM/DD/YYYY). If you cannot provide an exact date, leave that space blank and provide a written explanation on a separate piece of paper.
• If you need more space to answer a question, attach another sheet of paper. Make sure you include the following information on each additional sheet of paper you submit:
  
  • Your Alien Registration Number (A-Number);
  • Any applicable dates;
  • Application Part and Item number; and
  • Your signature. 
• The application you submit must have an original signature.  We will not accept a photocopy or a scan of your signature. 
• When you submit your application, you must include the correct fee ($680.00) or a fee waiver request.  If you do not pay the correct fee, we will reject your application.  Applicants 75 years of age or older do not pay a biometric fee so the total fee is $595.  Also, military applicants filing under Sections 328 and 329 of the INA do not have to pay any fee.
