let's assume i apply from Pakistan but it will be more complicated because, I don't have an active job/salary etc, so it will definitely make VO thinks that I am trying to get there by any mean.
i am sure someone has gone through this hassle and there should be a result, as i don't have any other objections like non-financial /family ties/ relation to the country, as per my research on this forms i found people do have 5 to 6 reasons with indicating family ties and ties to the home country.
i have to find someone who went through this process and how he/she overcome this.
You are not even living in Pakistan, how would the visa officer believe you will leave Canada and return to Pakistan after your studies?
There is no 100% guarantee that you will be allowed back into Saudi Arabia after you leave for Canada and complete your studies, since you're not a citizen of Saudi Arabia.
