If you extend it inside Thailand you will need to provide all the original documents you used to get it, and they need to be updated, including your courses.
Three months minimum as of now, and as more abuse is recognized it will progress to 6 months minimum in the near future, as has happened at other Thai embassies/consulates. The required times change monthly.
Padkrapow4549 you may not like it, but they change things as they see how they are being abused. Had the other person you referenced already been taking Muay Thai classes, and not brand new at it? Everyone uses the same embassy in Vietnam for Muay Thai classes, so that embassy sees what is going on. There are some "reputable" gyms that have more people signed up for classes than their gym can handle...lolol
Anonymous participant be fully aware that you will need all the documents you originally applied with updated. It is much easier just exiting and returning.
the staff at hospitals have limited English skills, but not the actual doctors. You need to talk to the doctor directly, not anyone else. The doctor will know what a treatment plan is. Go back to Thailand, and make an appointment with your doctor. That is what you need to do. The cost of what you would spend to enroll in enough Muay Thai classes, now at 6+ months, would easily pay for your flight back to Thailand to meet with your doctor.
One simple question. Did you submit a written treatment plan from your doctor, or just past appointments, as it sounds like you did? If not, that is why you were rejected. You need a written treatment plan from your doctor. With that plan your approval greatly improved under the medical category. They don't care at all about how long, or how much you've spent, or that you have insurance. They only care about the written treatment plan for your future treatments.
