Hi All, Seeking some clarification on the "medical visa". My tourist visa expires April 20, I would like to start a medical visa for dental work before then. The work should take 2 - 6 months to complete and doctor's office said they would provide certifying letter of appointments. My questions are:

* the Thai embassy site seems straight forward, just mentioning the doctor's letter stating appointment dates, but google results mention medical facility registration letter (from Ministry of Health?), and bank statement with minimum balance (not sure if they mean a US bank statement or do I need to open a Thai acct), so what exactly is needed?

* Thai E visa site, pop up window states you cannot apply for E visa while you are in Thailand. Is this really true, and if so would the in person Immigration office tell me if I am missing some documentation before applying/paying and getting rejected?

* Lastly, this is for dental work, so I could fly home and have it done, do they care if I am travel worthy or not to have the work done in my home country?

Any help is appreciated!
