Hi..i've got an acceptance letter for wiNTER 2013 FROM SHERIDAN COLLEGE for computer programming.but i'd like to change the course since i've done my btech in electroncs nd communication as i was told that taking a computer programming in pgd diploma course is not advisable. So i'd like to know that if i mail the col ppl for change of my course before gng for visa will they do that..?if so what will be the processing time for change of the course.
