Will I face issues leaving Thailand if my visa extension expires on February 7 and my flight is on February 8 at 2 AM?

If your visa extension stamp indicates you must leave Thailand by February 7, you must go through immigration before midnight on that date to avoid any problems. While your flight is scheduled for 2 AM on February 8, you should ensure you complete the exit process before the expiration date to avoid fines or complications. Although there is a chance of being fined for a short overstay, it's best to leave before the deadline.
