Don't bother getting a formal education if you don't need it. If you're already working as a product manager at 19 remotely then you're better off than most people in this group.
I've been working in tech for about 14 years remotely in Latin America and Asia. Don't worry about longterm visas right away until you're 100% sure. You can easily find a couple spots you like in SE Asia and rotate between them easily.
Hit me up if you have any questions
