sorry my stupidity, just being so proactive haha may we request doc verification now, since the case has been completed but no update yet if the embassy received the cr1 petition already? and if we have not been notified on the medical and interview date yet? and also advance medical appointment with slec

well you will need appointment letter to have medical and you can get that from the iv appointment link then you can have medical and pay doc.ver. well you can pay doc.ver. any time i guess but for medical you will need letter
