I'm currently in Thailand on a 60 day visa exemption undergoing long term medical treatment. Trying to decide if a DTV might be the best option for me over the next year or two. I kind of have a handle on what's required after reading here. I'm pretty sure I can qualify for the medical soft power since I have to see two specialists and purchase an injectable medication monthly. I also have labs scheduled in early March. Acccording to the doctors I have to take this medicine for the rest of my life.

I realize I have to leave the country and apply at an outside embassy. My question is which of the neighbor country embassies would be my best chance for the least hassles?
