From couple months iam hearing peaple have been asked to submitt thier passport to Islamabad visa office and they have got thier visa from Islamabad. Better submitt rather then wasting time. IRCC knows what they are doing.My wife received PPR on Jun 8th asking her to submit passport to Pakistan. We've emailed them back and requested to change visa office to Delhi. Awaiting a response. Please update if any of you hear back from NDVO. I will do the same.
