Hello.
Used the e-gates for the first time when leaving Suvarnabhumi last week. Now I don't have an exit stamp (30 day visa). I expect it will be okay when I come back in November but has anybody else been in the same position and experienced difficulties at immigration?
TLDR : Answer Summary
The use of automated e-gates when leaving Thailand means that obtaining an exit stamp is no longer necessary. While most people report that not having an exit stamp does not pose a problem, some individuals have experienced brief questioning by immigration officers upon re-entry. However, it generally seems that immigration officials are aware of the automated system and handle these situations accordingly.
