Just found out this forum. So I applied together in August 2019 under CEC Stream. Me being primary applicant living in Canada and my wife as a dependent living in India. File got moved to NDVO in November 2019. Nothing until this January. File was under 'Interview Required'. So received a request letter to provide proof and narrative of our relationship etc. My Biometric and re-PCC for my wife. Provided everything in a week and waiting again.
