What are the regulations and requirements regarding visas?
According to Immigration Canada, if students come to Canada to study English for less than 6 months, they do not require student visas. A temporary resident visa may be sufficient. However, you should consult your local consulate since some countries do not even require a temporary resident visa. If students wish to study English for longer than 6 months, they require student visas and need to show Immigration Canada a letter of acceptance as proof of their intention to study full-time.
