I got rejected for the first time for canada visa for Jan intake. I passed my GCE A level science with 53 % .... Ielts 6.5 not less than 6. Got offer letter from TRU on diploma in tourism management. Now my lawyer insist me to change the subject . And science related course are less available in that uni for May intake. What should I do? Should I apply again or not? And what are the chances?
