France and Spain are both members of the Bologna process, so the quality of education is very good and the diploma recognition is also very high. I suggest you consider whether to choose minority language teaching or English teaching course first. If you want to leave immediately after graduation, but haven't started studying yet, I suggest you choose courses taught in English. In this way, both the application and visa can be in English. Just take an IELTS test.

If you choose to teach in a small language, it is recommended to learn a small language immediately. The visa policies of the two countries have similar requirements for language ability. Spain can accept language schools to apply for visas, but France has lower requirements for economic materials. I suggest you consider it comprehensively and start applying as soon as possible.

I hope my answer is helpful to you!
