^ Truth be told, the answer is, it depends on your profile (e.g. whether you have any ties, a job offer, or none of them). Your explanation here is still not clear at all, but assuming you mean to say that you already have study/work experience in BC as an international student, then just wait for it to reopen in January. Also, most PNPs would only have streams for international students who graduated from a school in their own province. Therefore, BC would be the easiest for you.
If you intend to stay in Vancouver or elsewhere in BC, then applying to another province's PNP may not be the best solution for you.
