Hi there and welcome aboard!
Well, in general, it doesn't look good. In the past I would have said, go to a big international flight school in the US, get your CPL and CFI (certified flight instructor) and work for them as a CFI afterwards. There was a special visa program for international students which allowed them to work for the school for a limited period of time (J1 visa / 24 month) but I just figured out that this visa (program) doesn't exist anymore and I'm not familiar with the current visa regulations/program. I attached a link below, from a US flight school (in the past this school offered the old J1 visa program) now it's offering the F1 visa program, promising the possibility of employment.

Regrading Europe, in Europe many instructors are airline pilots who work on a part time bases for a flight school. There are only a few big schools who are in need of full time instructors based on their student load and usually they prefer hiring locals or former airline/commercial pilots. As a Non-EU citizen, without a work/residence permit, your chances of finding employment in the EU are pretty much zero.
I don't know about the situation in Africa and/or Asia, perhaps there are some folks on here who can provide some information.
Good luck!
