I just renewed my passport while my application is in process right now. In terms of new passport, do we have to inform them about the new passport or it's not necessary to inform them. I was thinking to send them a copy of my new passport through mail. How will i know if they receive my mail and update it with my new passport? Does anyone have the same experience as this? Please help me! Actually my papers has been transferred from CIO to CPP - Ottawa.
