Sorry for your refusal experience.As others have said already, please order GCMS notes before you reapply.I also see you have been refused under a very different section rather than R216.
I see you are from Kenya and I presume
that your IRCC visa office was in Nairobi.
While you reapply, please remember, IRCC visa offices, in Africa,particularly,in Nairobi & Dakar have very low approval rates for Temporary Resident Visas.
Because IRCC follows a controversial system of 'socio-economic profiling' of countries to assess likelihood of returning home.
This profiling system automatically reduces chances of approval for African applicants.
Exactly, that's why about TRV applications were refused in 2019 to about 80 African Artificial Intelligence Researchers for a conference in Canada.
In an official hearing in 2017, an IRCC officer openly admitted to one question,he was talking about applicants from Somalia,I quote:
"Q. So what is the criteria to determine the spontaneity of TRV applicant?
It would depend. Everything is relative to each case and is looked at individually. What we have to balance when we make a TRV decision is the reason to go to Canada versus the motivation to return home.
And the motivation to return to Somalia is not high for most people because most people, and if it were for any of us, we know where we would want not to be.
So you have to look at the reason to go back. It would depend. We would look at where they are flying from, in Somalia, depending on the military and other situations. So if it is a more stable area, we are more likely to issue a visa.
We look at their personal situation, their job, their financial situation in Somalia, of their connections to the country and that is what we do for all TRVs, and balance that"
The officer also said,I quote:
" I would say that it’s going to be an uphill battle for someone to convince us to issue a TRV from Somalia.So they would have to give us a very good reason as to why they would want to go back home before we would issue a TRV.
We had issued the TRV in a single journey documents for Somalia officials coming to visit Canada for various things. They have a good reason to go home, but having not served in Nairobi, I can’t tell you what other kinds of TRVs are issued but I would suspect very few"
So,I see,you have been refused by IRCC visa office in Nairobi, you can see for yourself,for a Somali national in Dadaab camp,the chances for getting TRV for Canada is near impossible.
I do not know about your personal background.
But since,you said,you are from Kenya,I would say you need a very detailed SOP because your battle for Study Permit is against IRCC's profiling system,which automatically reduces your chances.
