If you come in with Passport, 60 days, how long must you leave before entering on another 60 days?
TLDR : Answer Summary
Generally, when entering Thailand on a visa-exempt passport for 60 days, the minimum time you should leave before re-entering is just a minute. However, there are no strict regulations on this time frame; it ultimately depends on the discretion of the immigration officer who processes your entry. It's advisable to leave for at least a day to avoid any questions regarding 'visa abuse.' Officially, you can enter Thailand on a visa-exempt basis twice each calendar year, but if you plan to repeat this often, it's better to wait at least six months between entries.
