correct, but some gyms charge for the documents you need to apply for the visa. If you are applying for the visa yourself online, there is a charge….
There should be a fee for the classes, maybe a small fee for the admin/documents. Plus, if you are applying the visa yourself online, that fee on top. That’s it.
The Muay Thai gyms are gonna be busy. Usually it’s the gyms run by western owners that are better at the DTV. Because foreigners have to have their paperwork together so they should know what you need. Contact Tiger Eye Muay Thai. Bangkok. They are great and very professional
