You can't sponsor him Inland, you have to sponsor him Outland, which means the documents go to CPC-Mississauga for processing, then to the visa office responsible for persons of his citizenship. It does not mean you have to take him back there, it just means CPC-Vegreville is not the office responsible for processing your child's application. His being in Canada does not affect the Outland processing of the application.
Thanks for the reply. Much appreciated.
Does it mean that he can still live INSIDE Canada during the application process as long as I sponsor him outland and provide an address OUTSIDE Canada on his application forms?
Many thanks.
