At this point no one can answer that question. No one(that I'm aware of) has even applied for an extension at this point. But ..... I already entered, and exited Thailand. Will re enter in December. But don't start my class until January. I don't foresee issues or changes, but it's possible.
Hello. They have a DTV option. The owner is responsive by email. But I choose to go into the school to make sure I was actually going to get to cook meals. I think messaging the owner is a safe bet and just telling her your interested in "x amount of classes" to qualify for the DTV. But please check their site for updates. I got mine back in September and have no idea if things have changed.
