Question about American teacher's license

This question is only in the context of for working at public schools in Taiwan.

I currently have a substitute teacher’s license from America. It’s a real license from the state of Missouri. It is not a certification.

Is there any benefit to getting a full state teacher’s license , or is a substitute license adequate for getting jobs at Taiwanese public schools ?

How about a provisional license ? Is that adequate ?

I’d really like to give my heartfelt thanks to anyone who has the time and the inkling to answer this question.
