okay, so my case was transferred to NVC in the middle of December. We signed all the documents an payments by December, 29th. When the full-scale war started, I contacted an immigration attorney and got paid help with the whole process of transferring! My husband sent an email to the NVC, it was request about expedite case, saying that he would like our case to be transferred and interview to be scheduled immediately (if it`s possible) in US Embassy in Vienna because he`s concerned about my well-being because of Russian invasion. BUT the main argument for transferring the case to Vienna was that his aunt lives there so I`ll be staying there with his family and that`s the reason of transfer to Austria and not Poland, for instance. We got a respond from the NVC like next day! They said that they`re reviewing the request and will get back to us shortly with either confirmation or denial. Next day we got another email with new NVC case number saying our request was accepted and will be transferred to the US Embassy in Vienna. In a few hours I got an email from the Embassy saying I could come tomorrow (lol) or any other day next week at 1pm. They sent instructions on what documents I would need and instructions on medical check. Then everything else was fast and smooth. Had interview on Friday, got my passport with Visa sticker on Tuesday (had to pick it up myself). BTW interview was held in a CONSOLUTE, not in the Embassy.
