I have a few questions regarding getting a medical-based visa extension.

I have studied on studied on the internet, but I can't seem to extract definitive information as it pertains to my situation. I would appreciate any thoughts you have to offer.

I am currently here on a 6 month METV. The 6 months period and my current visa stamp is due to expire on May 19th.

It is my understanding that I can leave and return on a border bounce not long before May 19th and get another 60 day stamp even though the METV 6 month time-frame will have expired. That is true, correct?

That is all well and good, except I am due to get a double-knee replacement in Bangkok on April 21st. I have my doubts I would physically be up to doing a a border bounce only about 3.5 weeks after the surgeries. Especially since they are doing both knees at once.

I can get a letter from the hospital stating my medical treatment and a prescribed time after surgeries for recuperation and physical therapy. I would estimate that they would say 60 or 90 days after the surgeries. That would work for me.

My question is how exactly do I go about getting a medical visa extension? Just go to immigration with that letter and hope they grant me that extension from the date of the surgeries?

Another question is I would hope to be able to do it before the surgeries since I will not feel like traipsing around to immigration offices for quite some time after the surgeries.

One more question. Can I try to obtain the medical extension at the Jomtien immigration office, or do I have to do it in Bangkok since that is where the hospital is and where I will stay during recuperation.

THANKS A BUNCH!!
