Hi, anyone could join Thailand with a medical visa recently ? Or know a reliable local agent ?

I started an orthodontic treatment (invisalign) at Smile Signature in BKK in 2019 and I am staying in Vietnam. I can’t pospone my appointments anymore because because I need an important bite correction and my clinic doesn’t have partnership in Vietnam. They also refused to transfer my case as it would involve a partial refund.

I’m able to go through the process, quarantine, etc. The question is, is my case covered by the medical visa, does it worth wasting time and money or should I rather wait until the borders open?

Thx for your inputs
