Had to laugh at this DTV visa process. I got DTV in 4 days in London, no issues, I'm UK guy. Obviously I don't need a DTV as I can get do many days upon entry. The selling point to me was that my Ghanian wife could get spouse visa.
Made application in London while we are over, she gas 2 Yr type C tourist visa, paid the £300, then get told can't get DTV on a type c visa, gotta be a resident.
Visit to thai embassy in London, explained no thai embassy in Ghana. Finally they said you have to go to Abuja in Nigeria.
I asked thai embassy in Abuja about DTV, they said we are not giving DTV to African region at the moment, what a joke.
Maybe in time it will smooth itself out but I will take Thailand off the holiday schedule for the immediate future, not prepared yo travel to Nigeria, too dangerous in my eyes, plus monkeypox there.
