My NOA2 date is 1/6 and when I checked yesterday we were still at NVC. I do not have an exact date for sent to DOS as I never got an update from USCIS, but when I submitted a PI to NVC on 3/19 I received my case number. So rest easy, I know the waiting is hard, try and get all your ducks in a row regarding paperwork going forward. We will get through this
