USCIS has new fees and new forms

On December 23, 2016, USCIS released new additions to many of their forms, with dates effective immediately. USCIS will continue to accept previous versions of the forms until February 21, 2017. The N-400 is the only form not included in this exception. The previous version of the N-400 can not be used after December 23, 2016.
Any application or petition sent to USCIS postmarked after December 23, 2016, will be subject to new fees. For a list of new fees, follow thisĀ link.
