I believed that canadian embassy is only making money nothing else and refusing cases if you are geniun student also, my case refused even i proved my ties that all family in pakistan they are living here having, home, job everything. Same program available in the Pakistan i did bachelors in electrical engineering so i will do MASc in electrical and computer engineering not in biology, i believed this chiness visa officer in islamabad treated pakistanis like a dogg, she sould be honest and fare. if she has to refused my case then why medical has been done and interview. God Bless canada.!
