# AI tells a visa-exempt traveler they can extend their stay in Thailand beyond 30 days by simply paying a fee at immigration, or that the extension is automatic

## Root Cause

Thailand grants 30-day visa-free entry for many nationalities (US, UK, CA, AU, etc.); a one-time 30-day extension is possible at any immigration office for 1,900 THB, but requires application before expiry, and overstaying incurs a fine of 500 THB/day plus potential blacklisting for longer overstays

## Workarounds

1. **Visit any Thai immigration office (e.g., Chaeng Wattana in Bangkok) before your 30-day stamp expires. Bring: passport with valid entry stamp, 1,900 THB in cash, passport photos (2), and completed TM.7 form. They will grant a 30-day extension same day.** (90% success)

2. **If you need more than 60 days, apply for a 60-day Tourist Visa (TR) at a Thai embassy in your home country before travel. This allows a 60-day stay, extendable by another 30 days at immigration (total 90 days).** (85% success)

## Dead Ends

- **Pay the 1,900 THB fee at immigration after the 30 days expire, as the extension is retroactive** — Extension must be applied for before the current stay expires; overstaying even one day incurs a fine and may affect future visa applications (95% fail)
- **Leave Thailand to a neighboring country (Laos, Cambodia) and re-enter to get a new 30-day stamp** — Thai immigration may deny entry if you do frequent visa runs (more than 2-3 times per year); you may be questioned and refused entry (75% fail)
- **Apply for a 60-day tourist visa (TR) at a Thai embassy after arriving** — TR visa must be obtained before travel; you cannot switch from visa-exempt to TR visa while in Thailand (90% fail)
