Can I apply for a visa to take Thai language classes as part of soft power initiatives?

I am also interested in this, and as far as my research shows - DTV won't work for _just_ language learning. Some schools are currently creating courses "Thai language and culture" which might be more suitable for Soft Power depending on an embassy. In this group, there were several reports (but definitely not many) of success with TSL Chiangmai (the name of the school), although I don't remember from what embassy. Search for 'TSL' in the group, and you might find more info.

You'll need to apply for an ED visa, even though I've heard some people have managed to get one with a DTV. That’s only if you're genuinely serious about learning Thai, as language schools are now under scrutiny and must provide proof of attendance and other documentation. There have been some very recent news about this.

It's NOT wise to apply for the DTV visa as studying the Thai language. Although there are a few who have obtained it, too risky as it's not one of the Soft Power activities.

ED Visa can be a good choice if you want to do Thai language classes.

No that's an ED visa check in google DTV visa it gives you the criteria. You can't make your own up
