My Employer received a NOID (Notice of intent to denial) for pending h1b extension on 16th Nov. Application was filed in premium category. My employer told me that We have the time till 16 Dec to reply to the NOID query. Today, i saw case status update as "document is mailed" on USCIS site. I have got an email, since i had created my account on USCIS website to receive status alerts, where case status is showing as "post decision activity". I am confused about the case status update. We have not replied to the query yet. Have they already made the decision without waiting for the reply?
