I got the NOA2 notification and we just got onto it fast. The first enquiry it hadn’t been put into the system yet, but on the second it had been and got my case number. (This was like two days) my lawyer then submitted one, and had the case number through again and the next one I did was the case was transferred to London. Once it got transferred and I got the email to stay it was we was able to sort out the ds160 and the medical and interview.
