Are there long-term visa options for a 20-year-old dependent with a learning disability in Thailand?

A 20-year-old with a moderate to severe learning disability may not qualify for a standard dependent visa in Thailand. However, there might be options available such as a medical exemption that allows disabled children over 20 to accompany their parents on a long-term visa. It's advisable to consult directly with the local immigration office for specific guidance. Alternatively, the Thai Privilege Visa could also be a potential option.
