Excuse me, if you apply for skilled immigrants from Quebec, Canada, if you apply for studying abroad, can you only apply for PR at a local university in Quebec?

With PR, you can study anywhere in Canada. Because your PR was sent to you by the Canadian government, not Quebec. Go to Montreal. Montreal is still a big city, and universities can still teach in English. There are many English speakers in that city. Unlike what you think, you can't live without French. I have been to Quebec many times, and it is no problem to speak English in big places. You can take free French classes in Quebec. It's good to know two foreign languages.
