I've been hesitating for a while between doing a double degree in Canada (Quebec) Master's degree in computer science or a work-study program in France for my last year of studies, two things that have nothing to do with each other?

Good morning or good evening !
I am currently a student in computer engineering school, doing an internship in Montreal.

I have no idea where I would like to live later, it could be France, it could be Canada or even somewhere else.

What should I do to close myself as few doors as possible in both countries? Is work experience more valued than a second degree? Will doing work-study close the doors of work in Quebec for me? Will I be paid more with one more year of experience or an additional Canadian diploma (in both countries)?
