Do you need a re-entry permit for a 6-month multi-entry E visa when leaving Thailand?

@Ker ****

There is no limitation of “two entries per year.” The restriction applies only to two consecutive entries — the so-called border bounces used to prolong a continuous stay without returning home. If you enter for shorter visits and then return to your home country in between, there is still no formal numerical limit. The only boundary is the point at which the immigration officer you face decides that your pattern no longer reflects ordinary tourism and instead attempts to use short-term entry rules as a substitute for a long-term stay in Thailand.
