They just announced yesterday that they are reassigning 480 employees to the 1,000-member asylum processing team. Now I have no data on how large the K1 team is or what team these relocations are coming from but considering that number of employees represents almost a 50% growth of the already standing asylum team, a team that presumably would be comparatively well-funded/staffed, that seems like a large move in my opinion.
Also, on the NVC graph posted a couple days ago, there must be some skewing going on in there somewhere because the State Dept./NVC's website says they are currently processing cases received from the USCIS from 10 days ago. While that does not provide a "processed" date, it would suggest that their backlog is much smaller than that graph implies, otherwise we would see a greater lead time like we do at USCIS. Furthermore, there is evidence to suggest, such as "USCIS Analysis" on YouTube's case, that time from NOA2 to Welcome Letter was 8 weeks back in the first week in March, presumably that gap is closing, a thesis that is supported by the fact that the date which the State Dept. is processing is getting closer and closer to the same day. Another question is whether those 480 could have come from the State Dept., but that's just speculation.
@Obllak, I know you have already far and exceeded the call of duty, but if this NVC thing does become a concern, is there any chance you could start, when you have time, building a NVC version of your K1 sheet? I don't know if that's even possible and you seem much smarter on this stuff then me but just may be a valuable resource.
