@Bennett *******
oh maybe I misread, I thought he was planning to exit the country again while they’re processing his new education visa. That’s why I’m saying don’t leave, let them finish. I am not 100% sure but I’m pretty sure that as long as Thai immigration is aware he’s getting his new visa he can just stay until they finish processing his new one.
Whatever move you make, inform the school first that’s doing the paperwork for him. Don’t leave abruptly or mess with the process until his new visa is 100% done, then if he ever needs to go he can do so with a re entry permit. The school should know if they have enough time and if it’s okay or not, especially if they started the processing already.
