I-821 >> no $50 fee required but you still need to pay $85 for Biometrics. They may or may not ask you to come to one of the ASCs but you still need to pay that $85
I-765 >> regardless you need EAD or not but if you don't need EAD, you won't have to pay $380 fee
2 copies of recent color American PP size Photos
copy of I-94 front and back
