I own a gym in Bangkok. We've done lots of DTVs and no, there is not official certified DTV list. As long as the gym your training at is legit and has the proper documentation both as a busines and a sports entity you should be fine in most cases.

I speculate there are some random reviews just for their own protocols and to keep applicants aware and try to limit those trying to milk the system

Our gym has done a few DTV visas for HK nationals via soft power category.

A couple of things

1. They require evidence of 6 months of Muay Thai experience

2. 6-month course or longer is required.

3. They are generally more stringent.

That being said we have had successful applicants apply in Hong Kong. All were Hong Kong residents though.

If your in Bangkok for part of your stay -

If anywhere else, please do a search and you'll find many options

You don't need to prove anything but does a Muay Thai course with 15 lessons over 6 Months sound legit to you?

Can't you do a border run by road? Why would a plane ticket be necessary
