I applied for the PRTD on the basis of H&C but I got R-1 visa. That's why I'm asking how to deal with it. I won't be able to stay put in Canada right now because I'm pursuing a bachelor's degree and will graduate in July 2025.
How to deal with it is up to you. You can leave and then apply for a PRTD when you expect to return; it could be approved, or it could be refused, in which case you would likely lose your PR status (barring a successful appeal).
Or you could stay in Canada and, for example, transfer to a Canadian university. Or some other decision about education. You would not lose your PR status.
No-one can tell you the likelihood of the second PRTD being refused. The R-1 issuance instead of RC-1 gives at least SOME hint that they possibly didn't think the case for H&C was strong. Would they find a second PRTD app for H&C based on your decision to finish your studies? It doesn't sound very compelling, but I honestly have no idea.
Going back to your post here above:
I was a minor when I received my PR card and I had to return to my home because of some emergency, I had applied for a PRTD on the basis of Humanitarian and Compassionate grounds.
You say you were a minor and had to return because of some emergency, but based on having almost completed post-secondary education, you just stayed after you became an adult, and to a large degree as a matter of choice.
BTW the point of 'removed as a minor' is that your parents took the decision (whether an emergency or not is rather secondary in this context, unless that 'emergency' continued for several years, in which case 'emergency' may not be the right word). One of the ways they (reportedly) evaluate these removed-as-minor cases is whether the applicant tried to return as soon as feasible upon reaching age of majority. Having completed three years or more of secondary education, in most places after age of 18, would seem mathematically to put you right at the outer age of 'trying to return soon' after reaching a-o-m.
Anyway: I'm not trying to be argumentative and I do not know all the details of your case (maybe you started university at age 15). Just pointing out how it is possible this MAY be looked at.
At this point, you are an adult and the "removed-as-minor" thing probably not going to play any more, or at least higher risk. Is 'I wanted to finish my bachelor's degree' a compelling H&C reason? Don't know. Possibly they'd just give you a chance; possibly not.
Now that you're an adult, it's a not very enviable choice to have to make. Good luck.
