USCIS Released New Forms, Fees, Effective December 23
December 29, 2016
USCIS released without notice new form versions with effective dates of 12/23/16. The USCIS also indicated that no other form versions are acceptable (with the exception of Form I-129). On December 29, 2016 however, USCIS revised its position and announced that it will accept prior versions of forms that were revised on December 23, 2016, until February 21, 2017. The only exception to this grace period is the Form N-400 - USCIS announced the new version on December 13, 2016.
Please also note that regardless of the form edition submitted, applications and petitions postmarked or filed on or after December 23, 2016, must include the new fees or USCIS will reject the submission.
