my petition has gone through 2 rfes and a noid. my lawyer responded to the noid responses and we have proof that the package was received and signed on 8th Feb, today is the 15th day and yet my case status still reads "notice explaining uscis action was mailed". it has not even been updated to review yet. I work for a reputed us firm and have masters degree from an iv league college. I'm super worried as to why is the status not updating. any suggestions as to what could be the reason?
