Hi, I have been in Canada for one year and three months. I enrolled in mechanical engineering when I came to Canada, but it wan not my interest. Then, I took English upgrading courses and found out that my interest is computer science. I did not do so good in Computer science, so now I have decided to study business administration diploma, but my visa is expiring in december 2015. I just wanted to know if I would be able to renew my visa as Iv changed my program once. Your help would greatly appreciated. thank you for taking time and reading.
