Got DTV approved in Vientiane through the new evisa system. Submitted documents online on Jan 14 and had interview appointment at the consulate on Jan 17. Visa was approved right after. Thai consulate in Vientiane really seems to look into the bank statement. Had to open up the bank app on phone for the consular to check transactions against the uploaded bank statement. Not many questions otherwise. Total processing time 4 days (although I don’t think the interviews are held every day).
