On April 13, 2016, USCIS revised Form N-400, Application for Naturalization. The revised version is available at 

uscis.gov/n-400. You may continue to use the 9/13/13 edition of the form until August 9, 2016. We will reject and return previous versions of Form N-400 submitted on or after August 10, 2016.

Eligibility Requirements

The eligibility requirements for naturalization have not changed. For information on how to complete the form, and where eligibility requirements can be found, visit uscis.gov/n-400. For additional information refer to our Guide to Naturalization.

Changes You Will See on the Revised Form

We posted the draft form on April 9, 2015, for 60-day public comment and again on September 30, 2015, for 30-day public comment and received numerous comments. The changes we made:

• Removed the barcode. The 2D barcode technology has been removed on the new version of the form.
• Streamlined the application process for the customer. The revised form saves you time if a certain part does not apply to you.
  • For example, we added language on page one about your parents’ citizenship. Your answers will determine whether you complete Part 6, or continue directly to Part 7.
• Identified evidence. We added language to the form instructions to help you identify what evidence you need to submit with your form and bring to your interview.
