Can one apply for DTV online on thai e-visa, before returning to home country on a re-entry permit ?
I currently hold a business visa and would like to switch for DTV, but seems kind of risky to cancel my current visa before traveling to home country to apply for DTV
TLDR : Answer Summary
You cannot apply for the DTV while still in Thailand; it should be done from your home country after exiting Thailand. If you hold a business visa with a re-entry permit, you must cancel the permit at Immigration before leaving. Once your DTV is approved from your home country, you can return to Thailand and then cancel your Non-B visa thereafter.
