ChatGPT and Gemini gave me different Thailand visa-exempt day limits — which one is right?
TL;DR: As of 2026, most passports (including the US) get 60 days visa-exempt entry into Thailand, extendable once for 30 more days at an immigration office. If your chatbot said 30 days, it's likely recalling outdated 2023-era rules — always confirm against Thailand's official immigration bureau, not chatbot memory.
The Claim
AI models trained on older data can confidently repeat a rule that's no longer true — and travelers are getting caught at the border because of it.
The Evidence
A real Reddit thread in r/ThailandTourism shows a US citizen entering visa-exempt asking "now i hear some say that visa exempt, its only 60 days? and the new rules are impending? I asked chatgpt and gemini and they give different [answers]." Another r/Thailand user reported being "told off by customs" after relying on outdated chatbot guidance about re-entry timing. Thailand extended visa-exempt stays from 30 to 60 days in 2024, and many models' training data or cached answers haven't fully caught up.
Comparison Table
| Entry type | Current allowance (2026) | Extension available |
|---|---|---|
| Visa exemption (air entry, eligible passports) | 60 days | +30 days at immigration office |
| Land border entry (some nationalities) | May differ — fewer days in specific cases | Varies by nationality |
| Outdated/old chatbot answer | Often states 30 days | N/A — incorrect for most current entries |
Step-by-Step
- Check the Thailand Immigration Bureau's current website or your nearest Thai embassy page before booking travel.
- Screenshot or save the current rule with a date stamp in case of a dispute at the border.
- Don't rely on a chatbot's recalled number without cross-checking an official or recently updated source.
- If extending your stay, apply at a local immigration office before your visa-exempt period ends.
- Track your cumulative days if you're doing back-to-back visa-exempt entries, since annual limits can apply.
FAQ
Why did my AI assistant give an old number? Models can reflect outdated training data or a cached web result that predates the 2024 rule change. Can I extend past 90 days total? Generally no without switching to a different visa category — 60 days plus one 30-day extension is the standard ceiling. Does land-border entry get fewer days? In some cases, yes — land crossings can carry different or more limited allowances than air entry. What happens if I overstay? You'll face fines per day overstayed and possible entry bans on future trips.
