Based on what I have seen in multiple threads it really depends upon the visa officer, I have seen people within 2 months get their approval after AOR, contrastingly for few of them it has even taken 5-6 months after AOR.
hmm, I get it.. Agree and here most of the things depend upon the officer who is handling the application. I know as per website processing time is 12 months, so they can take their own time.
