I have applied for study visa in October 22 and got my study visa from IRCC for May 23 intake in December 22 . I deferred my course in Fanshawe College from May 23 to September 23 intake due to Chronic Dry eye disease that I am suffering from Feb 23. As I am not cured of my disease I am unable to travel to Canada and join my course of September 23 and so I have applied for refund from college. But as I have approved study visa they are asking me to withdraw my study visa. Kindly help in the matter.
