I brought cash for my initial bank deposit the day that I opened my Bangkok Bank account, but since then I use Wise as the rates are very competitive. Now I can draw money from ATM free of charge. No more 220 baht a time fee
If you decide to go ahead, be clear in your cover letter that you have only worked in this manner for two months and send documented evidence. Best of luck.
Why not enjoy a month in Vietnam while you get DTV? Why rush a visa that lasts 5 years? I did my application in HCMC and visited 30 different pho restauarant in the month that I spent there. I actually found Vietnam to be cheaper than Thailand. £10 a night accommodation and main meal of the day under £3. YOLO, take time to savour it.
I had eye surgery carried out in Bumrungrad hospital Bangkok. I contacted them with my UK macula degeneration diagnosis. They confirmed this with my UK eye surgeon. A treatment plan was devised and a medical visa obtained. This was before DTV existed, but it should be the same procedure now. I had an IMT implanted into my left eye, with three months of recuperation and training, then surgery on my right eye was carried out. In all, this process took eight months. Bumrungrad hospital are very professional and can provide any documentation needed. They have helped lots of international patients.
