Guys, I will put down what I analysed. It's in my opinion.
Your decision made is not based on Medical date, it is based on application filed date.
They work in queue, so now they started processing Aug Applicants and previous ones in which they require more time.
I did send them in EMail in October that I am coming in Diwali, please grant me Visa since they already had my passport for more than a month.
They did reply to me in January 20th thought that you need to fill consent form from your wife in order to provide info on your file. May be that pushed them.
Thirdly, my spouse passport has my name as husband name so that definitely helps and expedite the process.
Fourth, I was so confident about my application filled forms, docs, 160 page docs and 200 pics. I didn't leave any stone unturned before applying after 3 months of my marriage.
Lastly...Two P's...Patience and Positivity.
thanks everybody..hoepfully get my wife's PP back in 10 days so i come and dilwale dulhaniya le jaayenge..haha
