Dear kytebd,
Do you know Deva_Avik? One of the famous few of MI-01 forum? He helped the forum mates a lot. He waited more than 2 years and after his processing started he got rejected. The reason stated was job mismatch. Look page 787 in MI-01 bang forum. Everything starts when they start processing (when your file is In Process), that is looking and verifying your documents. One of my senior Engineer friend got rejected waiting almost 2 and half years. His name is Mansoor bhai. They were not convinced with his job description, that mismatched the NOC he claimed.
If the case officer thinks there are some issues that has potentials to go through, they will ask for additional documents along with you Medical or will ask for an interview.
Best regards, hhshumon
