Can you leave Thailand for 4 months with a DTV soft power visa after completing a 6-month course?

Yes you can return. Technically they can ask your reason for return and you should technically always say you’re coming back to do the activity you initially applied for. I’m not sure about cooking but for Muay Thai IF they ask yes you should say that you will train and you should probably have some pics of your kru and an idea where you trained previously etc.

They will likely not ask but if they do, do not say you’re coming for holiday. They want prepared people so it’s better to say you are going to train here and here paying monthly or daily.

Your Soft Power Program does not affect your movements because it is not an ED visa, which requires personal approval from the Education Department and Immigration Office, a fixed schedule, and visa extensions every 3 months.

The DTV visa was designed to be a more flexible solution, and your course has no direct effect on your visa after it is granted. So you can cross the border at any time — before the course, after the course, or even during the study process.

Don't listen to

He's being silly and pedantic.

Yes if you leave before your stamp expiry you're allowed to return.

I would say NO,.

You got 180 days to stay at arrival, if you managed to compete a 6 months course you must be in overstay as 6 months is longer than 180 days.

You have to pay the overstay fines first and will get extra stamps in your passport.

Of course you have a 5 year multiple entry visa, no problem.
