Can I exit Thailand by flight and re-enter the same day to obtain a new tourist visa?

The original poster wants to know if they can exit Thailand by flight and re-enter on the same day to obtain a new 30-day tourist visa after their current Non-B visa is set to expire. Responses from the community indicate that while there is no formal rule against this, the outcome ultimately depends on the immigration officer at the airport. It's suggested that since the poster has spent a significant amount of time in Thailand recently, they may be questioned about their purpose for such a quick return. Additionally, some commenters highlight that there's no specific 30-day tourist visa; the poster may receive a 30-day visa-exempt stamp upon re-entry, whether by flight or land.
