What are the current challenges and costs associated with obtaining an ED Visa for language courses in Thailand?

The discussion revolves around recent changes to the ED Visa regulations in Thailand, specifically for language courses. Initially quoted at 25,000 baht for an 8-month course with visa extensions handled by the school, a user later found out the same course is now priced at 1,700 baht, but students must manage their own visa extensions. There are concerns that obtaining an ED visa may be more difficult if applicants have previously held one, particularly for second or third visas without enrolling in a university degree. It was noted that proficiency tests may apply if studying the Thai language.
