Congratulations Bozance, it is always good thing when someone gets a positive response from VO.
I have contacted them regarding my application and they told me that it is in process, which means that they are checking validity of provided documents. I am not concerned because all the documents are in order and I believe that next week I will also receive medical request.
Regarding what happens prior to medical I believe that they are going through our experience and they request any additional documentation if they need.
I am not sure what happens after medical, what is the rest of the process, maybe someone else can explain that to us. Also, I saw in the spreadsheet that some people got PPR two weeks after their medical was received by VO. Did you guys also get a request to pay for the visa fee or it was just medical?
