PR Application moved to New Delhi Visa Office

I am July 2018 AOR. the only update i received so far was the medicals being cleared on July 25th. Background check hasn’t started yet.
Called up IRCC in November to know my application is with Montreal Immigration. GCMS notes look okay in terms of R10 , criminality and eligibility are recommend passed but the background check hasn’t started yet.

Called them yesterday and found out that my application has been transferred to New Delhi . I am 6 days away from hitting the 6 month mark.
The reason for transfer could be that i moved from US to India in August so its transferred now to local VO. But I wonder how much time NDVO is going to take as the agent told me they will conduct the backgroubd check.

Anybody in the same stuation or any advice?
