This tracker will help you check the status of your visa. If it is still at NVC or already at the embassy after the beneficiary got documentarily qualified. Also this is very helpful if the beneficiary is done with the interview and you are awaiting feedback from the embassy about the visa status. If you got 221G letter during the interview, it will also give you information dates when they updated your case and review it.
I hope this video will help you all too. Good luck!
Best regards to everyone,
