Are there Bangkok language schools offering long-term visas with minimal class hours?

The original poster is seeking recommendations for Bangkok-based Thai language schools that offer long-term visas while requiring no more than four hours of classwork per week. It is noted that most schools require a minimum of 100 hours of class every 90 days for visa purposes, with warnings about the legality of certain schools categorized as 'visa mills.' Specific schools mentioned include Duke Language School and Sandee Language School, the latter being described as effective yet of low teaching quality. Overall, the conversation highlights challenges in obtaining a legal visa under these conditions.
