Booked an appointment with BIH and asked for their visa confirmation - which they are very proficient at. I had spinal surgery. They even addressed it to Thai Embassy, London for me.
Just be wary of any extra requirements from whichever embassy you’re apply from.
Have to say BIH were brilliant. 72 hours after arrival - I had my op.
My case - my single doctors appointment from BIH, led to 1.5million baht in medical fees. Every penny well spent. Thats just in the first 8 weeks of being here. My recovery from surgeries, add about 35k per appt.
Maybe I’m the outlier. someone actually going thru with the treatment. But BIH was busy.
Not sure what more could have been provided by BIH though, til they met me, I was just some dude on email.
But they’ve given me my life back now and I can recover in a warmer climate.
Mine was approved on the basis of a consultation with an orthopedic surgeon. I did however also provide additional medical evidence, such as diagnostic tests and neurological report. No follow appt required.
