You selected the WRONG Thai E–Visa Subtype on the Thai eVisa website....
Looks like you want to get the Non–O Married to a Thai Wife: or, on the Thai eVisa Website it is = Non–immigrant (O) To Stay with Thai Family Residing in Thailand (more than 60 days),
BUT, you had most likely INCORRECTLY selected Non–immigrant (F) Family or Dependent of Diplomatic Officers/Officials based in Thailand
Do check and verify again that you had selected the correct Thai E–Visa Subtype from the initial window/menu
Congratulations on your DTV E–Visa from the Thai Embassy in Vientiane under the Workcation Category!
Did you get a request for an in-person interview at the Thai Embassy after paying cash for your DTV E–Visa Fee (with the QR Code print out to make payment)?? if so, how long was it between making cash payment and your interview??
