I just arrived in Bkk today activating my DTV, went smooth, no questions asked.
Here’s what documents I submitted when applied:
- Photo (not older than 6 month)
- Passport
- proof of residence (of my apartment in Germany)
- freelance contract and permission letter to work from abroad (specifically stating Thailand too)
- 500k baht bank statement (money was transferred just before my application, no necessity for proof of 6 month in my bank account)
Applied in Frankfurt, Germany. Visa was approved after 9 days.
Hope this information is helpful. If you have any questions feel free to ask.
