 It was more than half an hour and asked me to wait again. After 40 min, VO called and said sorry fora long time and asked me to verify the documents which I gave to him and took my passport with him and gave the white pamphlet, So I guessed he approved my VISA :) I said Thank you and have a nice day.
VO laughed at me and i came out at 10.45 am.

In the mid I lost my confidence but I was smiled as if i am getting fear.

Such a long post but this is my experience.
