Definition and severity
Overstay begins midnight after "admitted until" date on passport stamp or extension sticker. Each day counts — including day of discovery. Penalties escalate with duration. Voluntary surrender at immigration before arrest always preferable to airport detention or raid discovery.
Penalty schedule (2026)
- 1–90 days: ฿500/day, maximum ฿20,000 fine at voluntary surrender
- 90+ days: fine plus re-entry ban (1, 3, 5, or 10 years depending on length — officer calculates)
- Work without permit + overstay: separate criminal liability possible
Voluntary surrender process
- Attend immigration office (Jomtien for Chonburi residents) OR airport immigration before departure flight.
- Present passport, explain overstay voluntarily.
- Officer calculates fine + ban if applicable.
- Pay cash at cashier — keep receipt.
- Exit Thailand within given timeframe — often same day for airport surrender.
Office vs airport surrender
Jomtien/immigration office: better for overstay >30 days, more time to process, less flight pressure.
Airport departure day: viable for short overstay if extra hours budgeted — risk missing flight if queue long.
Re-entry after ban
Ban enforced at all borders — attempting entry during ban extends trouble. Wait full ban period or consult lawyer for documented medical emergency exceptions only.
Prevention systems
Expiry countdown with 30/14/7/1 day alerts. Calendar sync. TM30 and 90-day separate from visa expiry — triple tracking.
After surrender — clean re-application
Overstay history on file. Future visa applications may face scrutiny — honest disclosure, clean subsequent compliance rebuilds trust. Never compound with fake documents.

Real scenarios from Pattaya (2026)
ED student missed extension during school break. 12-day overstay — ฿6,000 fine at Jomtien, extension processed same week after fine paid. Clean record if no repeat.
Retiree confused extension date with 90-day date. 45-day overstay — ฿20,000 cap hit. Re-entry ban not triggered under 90 days but file flagged — officer warned on next extension.
DTV holder thought 5-year visa meant no extension needed. 180-day stay expired — 30+ day overstay before surrender. Fine plus departure; DTV validity remains but compliance stain complicates next extension.
Do not do these
Hide and hope — raids and airport scans find overstayers. Buy fake exit stamps — criminal fraud. Pay agent promising silent fix without surrender — often scam extending overstay.
Legal counsel — when to use
Overstay 1 year+ or criminal overstay with work illegal may need lawyer before surrender — voluntary surrender still better than capture but legal advice reduces ban length in edge cases. We refer complex cases to Pattaya immigration lawyers — we are not a law firm.
Impact on future visa applications
Embassy applications ask overstay history — declare honestly. Single short overstay with voluntary surrender rarely blocks DTV; repeated overstays block Non-O.
Keep surrender receipt forever — scan to cloud. Future visa applications may request overstay history proof showing fine paid.
Family and dependents
Primary holder overstay may affect dependent stamps — surrender together if whole family out of status. Children on O visa need parent fix before school enrollment continues legally.
