We’re on the same boat. The embassy sent me an email stating that they received the paperwork from the NVC on 6 November. We received the instruction packet on 16 November but they said they sent it the first time on 8 November. We completed the DS-160 on 23 November. I sign up to schedule an interview but i have not had any luck. I check every day but nothing. Our validity date for the NOA 2 is until 12 January but we have everything ready except for the medical, fingerprints, and final interview. Hoping they add appointments soon. Going crazy over here. Has anyone been successful with a similar timeline?
