This is one of the most common questions travelers ask about Thailand, and the confusion makes sense because the official rule seems straightforward but the actual enforcement depends on patterns immigration officers look for.

The Official Rule

Thailand allows visa-exempt entry for eligible passport holders (including US, UK, EU, Australia, and many others) for up to 60 days per entry. There's technically no written limit on how many times you can enter per year.

What Actually Happens in Practice

In practice, immigration officers have discretion to question travelers whose entry patterns suggest they're trying to live in Thailand without proper visas. What they tend to focus on is not the number of entries alone, but the combination of factors.

When People Get Questioned

Most people don't run into issues because they broke a rule, but because they don't realize which combinations of timing, previous extensions, and entry method tend to trigger extra scrutiny. For example, someone who's been in Thailand for 5 months cumulative in a year, with multiple back-to-back land border entries, is more likely to be questioned than someone with 3 separate trips spaced throughout the year.

The Bottom Line

There's no magic number of entries that's "safe" or "too many" because immigration looks at your overall pattern, not just a count. Most short-term tourists entering 2-4 times per year face no issues. People who spend 6+ months cumulative or do frequent border runs should understand they may face questions.
