What is Canada's asylum visa and what does it do?

This is a refugee visa. If you are persecuted by your own government and it is not your own fault, you can apply for political asylum in Canada. After obtaining a political asylum visa, you can live in Canada or apply for a work permit from the Canadian government, provided that you cannot support yourself and must work in Canada. You can also apply to study in Canada, but you can't enjoy the funding from the Canadian government. If you do well in Canada and pay taxes on time, you still have a chance to apply for a Canadian green card.
