Do DTV visa holders need proof of onward or return travel when entering Thailand?

They have asked this ticket when we apply for Dtv visa at thai embassy

Only been asked Heathrow and Vietnam airport why I don’t have a return and simply explain I have a DTV

No

Only place I’ve been asked is. Birmingham airport. Air India. lol. He didn’t have a clue about DTV. Schooled him

It’s not necessary, although the inbound airline might ask for it.

depending on immigration officer

Never been asked for it, never traveled with a return ticket. Have entered and exited many times.

No. I've been in and out 3 or 4 times and have never been asked about an onward or return flight. If you ever are, it will mistake likely be an airline. In that case Ibwoukd show them and explain the DTV and how I am not certain of my timeline and where I am going at the moment. Hopefully the person asking will understand. If not, i will jump on my phone and buy a cheap bus ticket or refundable flight and then cancel the flight or chalk the cost of the bus ticket up to the cost of doing (DTV) business.

Bus ticket is cheap

Some airlines might require one, what i do is book a fully refundable ticket and cancel it when i land in Thailand

Get a cheap burner ticket to somewhere close .. or just book a week in vietnam return for when the 180 is up then come back ..

No need for onward flight
