I'm currently in Vietnam. I'd like to transit via DMK to Cambodia, but I heard I'd have to go through immigration at DMK, which I'm nervous to do (long history of exempt entries in Thailand and the dreaded volunteer visa). Is this true? Frankly if I did have to, and they let me through, I'd prefer to just stay in Thailand.
TLDR : Answer Summary
The user is concerned about the need to pass through immigration at DMK airport during a transit to Cambodia from Vietnam, especially given their history with visa exemptions in Thailand. Commenters clarify that if traveling on a single ticket and not self-transferring, they would not need to enter Thailand through immigration. Recommendations suggest booking direct flights or using a fly-thru ticket to avoid complications.
