All of this is anecdotal. All we can say is that people will come to us—this is on the business side—and they will complain that they weren't given a visa. On the face of it, we know these people are bona fide business people, and it's inexplicable. I'm not saying the immigration officer didn't have a valid reason, but we don't know what it is.
A special problem that relates to the issue of student visas is this. It's not just a rejection rate, it also has to do with the sequencing of the visa process vis-à-vis the university admission process. My understanding is that with Australian universities the two processes are parallel; in fact, they are totally in sync, in that if you get accepted into an Australian university, you then get your Australian visa as well. It has to take place at the same time. However, in the case of a Canadian university, you first have to be admitted into the university, and then you need to go through the whole visa process, which could take--I don't know how long, but we're talking about months and months and months.
You know what this does to the potential applicant. If you know that you've been accepted into Australian National University and have an Australian visa already, but you have to wait another eight months or twelve moths or whatever to figure out if you can get a visa to attend U of T, you take the money and run, right? So this is a problem.
