How many times can I enter Thailand on a tourist visa if I travel to neighboring countries frequently?

Expats who frequently travel to neighboring countries and return to Thailand on a tourist visa generally have some flexibility, but there are important guidelines to follow. While some individuals have successfully entered Thailand multiple times within a short span, there are formal limits, especially for land border entries (typically two per year without a visa). Air entries have no strict annual cap as long as visitors can prove sufficient funds and have proper documentation. Regular travelers might face scrutiny if their entry patterns are deemed suspicious, so varying the mode of entry and having clear proof of travel intentions can help avoid unwanted complications.
