Because I'll be graduating in a month and have to cancel the visa soon, I want to extend my stay as I look for jobs or prepare for the examinations required for the master's degree. The start date also would probably be months after I graduate.
Sorry, I meant to say that most language courses offered are for the Thai language. Courses in other languages like Japanese or Chinese are more expensive as I also need the visa. Although opting for those might be the preferable choice if I want to avoid such concerns.
