, see my other replies above re expiry of my Thailand retirement VISA. I didn’t need a VISA to enter Vietnam. I did include hotel accom booking in Hanoi as well as entry/exit stamps from my passport for proof I was applying from outside Thailand. Not sure what your agent means when he says fees increase if your retirement VISA expires. All I can say is I didn’t pay any extra fees and my retirement VISA had expired when I applied for DTV. However I didn’t use an agent so maybe he’s referring to the agent fees increase.
