Thanks for the reply.
Unfortunately, I don't really know much about the situation regarding their current employment contract situation and future employment. From what I gather, the new school doesn't want them to leave the country as the new semester starts at the beginning of July and they need them to teach.
I was asked for advice from a close Thai friend regarding the visa situation last night. I told them that I believe it may be possible. They were communicating this directly with the director. I suggested that it might be best not to rely on my own lack of knowledge and instead wait for the advice from the experts on this forum!
I really appreciate your quick response.
Have a good day.
