What are the rules for re-entering Thailand to renew a tourist visa?

When renewing a tourist visa for Thailand, there are no strict rules regarding how soon you can re-enter the country after leaving. The key factor is the discretion of the immigration officer at the point of entry, who will consider your past visit history. While travelers have the flexibility to leave and re-enter, it's important to be cautious about repeatedly entering on tourist visas, as there can be scrutiny, especially with recent tightening of regulations. Therefore, if planning to make frequent entries, it's advisable to be aware of the potential for being questioned or denied entry.
