MMM.

That’s great news. I’m really happy finally you are close to it. I hope to get this call and email soon for redo medical. Best wishes 

When did you receive an email for re-medical. I guess it’s good sign. No matter status shows AP

AoA. I had my F3 IV interview at US embassy in Islamabad on Oct 23, 2018 which went very well. CO asked asked all the questions with me and nothing had asked by wife and 3 kids. And, questions were about my aboard travels which were all my officials. At the end she gave me white slip 221g process. Rest of my 4 family members status shows “READY” while my status is “Admin Process” though I had visited States 4 times and my visitor visa is valid 2021.
i know no one can predict AP waiting time but I m sharing my case if someone of near to my interview date to get an idea of waiting time. 

From your post and call from embassy shows his passport will return with visa stamped this week. Keep posted on progress
