Can I extend Thailand DTV beyond 180 days without leaving?
Yes. Each DTV entry gives 180 days, extendable +180 days once per entry at Thai Immigration for THB 10,000. Total 360 days per entry. After that, a border run resets the 180-day clock for 5 years. NPT handles the extension paperwork.
Detailed Answer
The Destination Thailand Visa (DTV) grants 180 days of stay per entry within a 5-year multi-entry window. Each 180-day period can be extended once for an additional 180 days at any Thai Immigration office (Chaeng Watthana, Phuket, Chiang Mai, Pattaya, etc.) for a government fee of THB 10,000, giving up to 360 consecutive days per entry. After 360 days, a border run (Laos, Cambodia, Malaysia) resets the 180-day clock and allows another 360-day cycle. NPT handles the full extension flow: 90-day reporting, TM47/TM7 forms, financial-proof re-confirmation, embassy/immigration appointment booking, and accompanying you to the immigration office in any province.
