applied dtv soft power-medical online at thai embassy washdc on 3/10. received dtv on 3/14. used: 1. most recent credit union monthly statement, all pages. 2. official, chopped & signed, initial appointment letter from bnh diagnostics center. i have some chronic knee injuries that need ongoing treatment. 3. the rest of the required documents per thai evisa website. i also offered evidence of alot more $, my worldwide medical insurance documents and a cover letter but my atty demurred.
cost: $300 initial medical appt, $400 evisa fee, $400 atty fee. i retained an atty because i needed fast & sound advice (which i certainly received), and proper application formatting. money well spent on an atty for something important to me. i wasted way too much time worrying and researching on my own.
good luck all.
