Well, I had a successful interview along with my spouse. It last for 15-20 minutes only. General question from my application only. Asked few questions about what I liked most of my spouse. The best part is the VO did not take interview separately in My case. Though in first 10 minutes it was mine interview and and then VO called my spouse and asked the same few question which I'd already replied and then VO told us that she was convinced that our is a genuine relationship and she is approving my application of permanent resident in Canada. VO also told me that I have to wait at least for two months to get my PP back with Visa. And then on 06th November, my eCas changed from "Application received" to "In Process" and after few days I'd noticed that My father's name along with mine was added on eCas .
it is almost 42 days passed and I hope that I might get my PP with Visa before 31st December.
But Waiting is really Killing me.
