Does DTV holder visa need ETA?
TLDR : Answer Summary
DTV visa holders do not need an Electronic Travel Authorization (ETA) to enter Thailand. The ETA program has been postponed and will reportedly apply only to visa-exempt entries, while individuals holding any type of visa, including tourism visas issued by embassies, will not require the ETA. The implementation of the ETA has not yet been finalized, and updates are awaited.
