DTV approved in London. Wife applied first as workcation showing work/income documents etc. Hers was approved in 3 days then I applied as spouse with her DTV number and showed marriage certificate and certified translation (we were married in Italy). They requested further documentation from me, original Italian marriage certificate and an apostilled translation. Got these in 3 days and resent to Thai embassy and approved the next day. Landed on Tuesday this week from London with no issues at the airport. Also we had no return ticket out of here and it wasn’t asked for, heard a few people have been asked for them though, some have even had to buy one at the airport before entry allowed. Something to be mindful about.
