Most students will need a Canadian Visitor Visa (TRV) in order to enter Canada. Please see the following application instructions.
The nearest consulate is located in New York, NY. You must plan carefully if you are mailing your Canadian TRV application as your original passport must be included with your application materials. Hence, you may not be able to travel (flying within or out of the U.S.) until you receive your passport back in the mail. Normal processing times range from 3-8 weeks.
