How can I apply for a 5-year DTV visa for medical treatment in Pattaya and what hospitals can provide the required documentation?

When applying for a 5-year DTV visa in Thailand for medical treatment, it is important to note that hospitals in Pattaya are not officially authorized to issue a medical certificate. Instead, you need to obtain a treatment plan from the hospital, which you will then submit as part of your DTV visa application. The acceptance of this plan is subject to the embassy's discretion. Additionally, it is suggested to search for services that connect patients with hospitals or clinics that can provide the necessary medical care.
