I appreciate your concern. I too agree its in officer discretion, however, they cant just refuse you because you are from Asia or Africa. You will get a letter why you are refused or accepted. The people who got more than 70 might be rejected if their occupation, study seems not to provide economic growth in Sask. Also, if some of your documents are proved to be fraudulent, they will reject your application. I am too SINP applicant, i have called SINP office several times, i found them to be nice every time i spoke to them. If you think something else, thats upto you but there are several people in a hope so respect their desire.
