If new Delhi is the RMO for you, it will take at least 3 weeks for them to process the medical, then your VO in Islamabad will b able to access it after that. But since your VO has a really long processing time, I would guess it will b awhile longer still, unfortunately. Think once they request your passport and visa is reay to b issued, it takes 5-10 business days before they ask you to collect your passport n visa. Hang in there!
