I applied for May intake and i got visa approval late. When i reached at college classes were already going on and college is not allowing me to sit in the classes and advised me to defer for september. I have already got the deferred offer letter. But college authorities are saying to me that my study permit will be expired after 90 days if i do not enroll and said me to go back to my country and come back for september. What i can do? I have visa only for one year. September is so far. Please provide me some suggestions.
