What is the best way to obtain an ED visa in Hua Hin and what are the associated costs?

To obtain an ED (education) visa in Hua Hin, it's recommended to contact local educational institutions directly. Insight English is mentioned as a potential option that can assist with the application process. Costs may vary based on the course of study and specific circumstances, and it’s essential to confirm the details with the chosen school. It's also advised to look for a school that can facilitate the conversion from a tourist visa within Thailand, as attempting to change at the Thai embassy in New Zealand can be quite costly.
