One of the easiest ways to extend your stay in Thailand. Average price is 25,000 – 28,000 baht per year.
Great feature of Thai student visa that it’s possible to extend it up to ten times (10 years). It means that person can legally live in Thailand without breaking the law and having no permanent residence and citizenship.
Visa cost also includes foreign language course. It’s up to you visit them or not. If you send child to school, and he gets a student visa, parents can get “non-o” accompanying visa, which also gives parents a right to stay in Thailand.
