Thank you for your response.Hello,
1. Many people here in the forum, including me, have received pre-arrival in the November 2020, it’s almost 2 months no PPR. So, nobody exactly knows what NDVO is currently doing.
2. Once your wife receives the letter to submit passport for PR, and if she is in Canada, than you can submit the passport in Ottawa (I think), and they will stamp it and give you details about landing! Also, I believe that you have to update her address with IRCC once she is Canada.
Thanks
