What happens at the automated departure gates for travelers who are on overstay in Thailand?

When attempting to leave Thailand through automated departure gates, individuals on overstay will find that these gates remain closed. Instead, they will be redirected to a manual immigration desk where they can address the issue of their overstay and pay any associated fines. The experience for those with minor overstays is typically straightforward, but it's advisable to maintain a clear immigration record for future travels.
