What are the requirements for extending a Soft Power visa after the initial six-month classes in Thailand?

For the Soft Power visa, after completing the initial six months of Muay Thai or cooking classes, you generally do not need to show proof of booking additional classes for subsequent stays. However, if you seek to extend your stay while in Thailand, you may be required to present updated documentation similar to what was initially submitted to the Thai Embassy. During re-entry, proof of continued classes may not be necessary.
