Here is what they instructed me in my first AOR:
Beginning April 1, 2010, residents and citizens of Pakistan wishing to apply under the economic class will submit their applications to the Canadian High Commission in London, United Kingdom for processing instead of Islamabad, Pakistan.
You are therefore requested to submit a complete application to the LONDON visa office.
Where CIO instructed to send your Full Documents?
I believe, it's London, United Kingdom....
So please mention "London, United Kingdom" in Requested Visa Office.
Seniors please comment.
