I'm Asian American and besides one negative experience (mentioned below), this has not posed a problem for me teaching at international schools in Asia. That said, I think if I had a thick accent, it might be a different story... This is unfair and unfortunate but it sometimes happens that Asian (old fashioned) parents don't want their children to have an Asian teacher but of course, it is dependent upon the open mindedness and internationalism of the school itself. I have heard of a couple stories from Asian teacher friends about this very issue coming up at job fair interviews but perhaps we can take it as a warning sign for a not so good school.

I was working at a school in Indonesia a couple years back and had a very narrow minded and incapable principal running the show. I was the only Asian American class teacher and she seemed to give me a much harder time than the Caucasian teachers there. She left me alone once I proved myself that I could teach well but by then, I had already made up my mind to move on to a better place.

Just do your research on the school and ask to speak to current teachers on their experience there to get a better feel of the place. Communicating candidly with the admin about school culture and open-mindedness is key. I think if it is a real concern, they will bring it up first.

By and large, this doesn't seem to be a problem for Asian American teachers.
