At OnlineVisas we have not witnessed such a major spike in the number of Requests For Evidence (RFE) and denials (USCIS data indicates 400%) in the recent past.
The severity of consequences for even minor clerical mistakes is expected to increase as USCIS officers are no longer required to issue an RFE or Notice of Intent to Deny (NOID) as of today, Sept. 11, 2018, when PM-602-0163 goes into effect.
