Thanks, i will wait them for PPR and request to change visa office then. It is just a bit tricky because I will be moving from Europe to South America soon so hopefully I can settle everything once I am in south america since I will be there for about 3 months then return to Canada in August.When u receive PPR, only at that time, you can request to change your visa office. So you should wait. If you change your address for a long period, you should update your new address to CIC through CSE. If you will come back soon like 1 month, you can just go without noticing CIC.
One more question if I may - do i just send the request to change visa office through CSE? or there is a different email I should use for that?
Thank you so,so,so,so much for your response! I really appreciate it.
