Indeed. I have just a modest window on that.
When I was in London, Mr. Orr, who appeared before the committee here, who now is assistant deputy minister responsible for operations, was at the time the head of the immigration section in London. So we had worked together. All I know or don't know may come from Mr. Orr.
I learned a lot about that discretion, and the kinds of training the visa officers get is actually quite good. They are given guidelines to follow. For some countries it's a medical assessment that's being made. For other countries they are looking for evidence of criminality in the background. In other countries they are looking for the family relationships that might induce people to stay over the time.
