I'm a little confused, visa-exempt and visa-waiver, isn't that the same. entry into Thailand that does not have to apply for a visa, in Korean , they will get 90days. Good point about overstay stamp in passport while enrolling in a school, could complicate things
thanks for your help, still trying to decide which way i should go, i like the visa exempt or tourist visa idea. As long as i can get the nonO visa once in thailand.
As i've had a long stay visa based on retirement which expired while overseas, i have the basics setup such as my thai bank and 800k waiting for me.
