How can I apply for a long-term visa or student visa in Thailand?

Thank you very much.

The choices I had was: take an in-house teaching position at the institute, and at a slightly lower salary. The second option was being posted by the institute, outside of the city of Chiang Mai. That could be 30 or more km away. There's pros-cons to those two choices, but, obviously, working in CM is preferred; unless you want the teach-in-small-village job. It's sort of akin to the Peace Corps "feel". That latter used to pay about 29k plus per diem. Not including, the mid-break; you'll need to take up side work at local English accademies, online teaching.

if you're happy and able to study at university level then you could easily get 2 years or longer out of an ED visa. But if you're just looking for a visa with little intention of studying you are going to struggle
