Can I visit Thailand for 3 weeks multiple times a year without issues?

The consensus among community members is that visiting Thailand multiple times a year for short holidays of about 3 weeks each is generally acceptable, especially if you can demonstrate that you are a genuine tourist with a return flight. However, the immigration officer's discretion plays a significant role, and entering without a visa might be risky. It's advisable to apply for a tourist visa beforehand if planning frequent entries.
