I'd like to answer that question, and also the question raised by Member Menegakis.
For example, Member Menegakis, you said we have x number of students who are allowed to come in, which is fantastic, but how many of them are able to stay without their families? For example, I had a student whose husband was a highly successful businessman. They had travelled to the U.S. and had U.S. visas, Schengen visas, and they had travelled throughout the world. She was refused a visa to Canada because they wanted to keep some ties back in the country of origin. What that resulted in is this highly successful student having to return back to her country. The criteria that was applied by the officer was completely wrong, applying temporary intent instead of dual intent, whether or not that person is likely to obey the laws. All of the travel history has shown that they had not overstayed in another country, such as the U.S. or Europe.
You have other criteria where, for example, you're not allowing the families to join families. I had a case, for example, of a child, who is Canadian because his father is Canadian, who has cerebral palsy. The wife was not able to join the families as well, so the criteria results in serious consequences to the families.
