We got a call yesterday from NVC. The guy said we hadn’t sent the proof of my spouses domicile. I explained it was sent and I could actually see they hadn’t been opened, I’d sent them 7 and 13 Dec. Even though he said I’d not sent them. Then he said oh yes they are there but he isn’t actually allowed to open them. So I’ve sent them yet again and the waiting continues. If they do send you an RFE for anything I would suggest adding them onto both urs and ur spouses as he said that might be why they hadn’t opened mine. Who knows but worth a try. Good luck and hope this bit goes smoother for you.
