Will I face issues exiting Thailand if my tourist visa expires on the 15th and my flight is at 1 am on the 16th?

The consensus among users is that as long as you pass through immigration before midnight on the 15th, you should not face any issues. Experiences shared indicate that late-night flights after the visa expiration date are generally permissible if you leave the country before the next day begins. However, it is advised to pass through immigration earlier, potentially around 10 PM, to avoid potential complications.
