My wife case was initially Nikah only, but, in summer of 2017 I went for Rukhsati and Valima and voluntarily sent my travel proof, pics, moneygram receipts, communication proof after my trip to IRCC. After that I did not get any updates/ requests at all and then from nowhere I got PPR. So my advice for waiting cases is that please be patient and wait till 10-11 months and hopefully your case will be done in one year.
