1. How long did it take between NOA2 approval and NVC creating case number?
Check my timeline.
2. How long did it take between NVC creating case number and embassy notifying you that they have received the case from NVC?
They never notified me until it was shipped out. Unless you contact them and ask, you won't know.
3. How did the embassy communicate to you that they have received your case, was it via email or mail and was the notification send to the petitioner or the beneficiary since Form 1-129F only asked for the petitioners email address?
Email. Only I, the petitioner ever received emails, which I then forwarded to my fiance if necessary.
4. When in the process did you apply for the DS-160?
I applied as soon as I got my case number.
5. How long did you have to wait to schedule an interview with the embassy from the time the embassy received your case?
The rules around that are embassy specific, but I was able to schedule when I got my case number and my case status was ready.
6. How far out was the interview date from when the embassy received your case?
Check my timeline.
7. On the NOA2 Approval letter that was sent from the USCIS, it says there is a 4 month "Approval Notice Valid" period. What does this mean and do you have to take any action if approaching this deadline?
Nope. They can extend it at/after the interview if needed.
