On December 23, 2016, USCIS posted a large number of new form versions with effective dates of December 23, 2016, to its website and indicated that no other versions of the forms would be accepted

After considerable pressure from AILA and other stakeholders, USCIS announced on December 29, 2016, that it will accept prior versions of forms that were revised on December 23, 2016, until February 21, 2017.

When new fees for most of the USCIS forms went into effect on December 23, 2016, USCIS published updated versions of the forms at uscis.gov/forms. USCIS strongly encourages customers to submit these new versions, which are updated with the new fees and have an edition date of 12/23/16. USCIS will accept prior versions of forms, with the exception of Form N-400, until February 21, 2017. However, all filings postmarked 12/23/16 or later must include the new fees or USCIS will reject them. USCIS will accept only the 12/23/16 edition of Form N-400, Application for Naturalization. The updated forms are currently available only at uscis.gov/forms, where all of the forms can be downloaded for free.
