What happens if I overstay my visa?

Overstaying incurs a fine of 500 THB per day (maximum 20,000 THB). You pay at the airport when departing. However, if caught by police during an overstay (not at departure), you face detention at the IDC (Immigration Detention Center) and potential blacklisting. Overstays over 90 days result in a 1-year blacklist. Over 1 year: 5-year blacklist. Always maintain legal status.

Can I use an agent for visa extensions?

Yes, many expats use agents for convenience. Agent fees range from 3,000-8,000 THB on top of government fees. They handle document preparation and submission. For straightforward extensions (DTV, retirement), doing it yourself is easy and saves money. For complex situations or if you can't meet the financial requirements directly, a reputable agent can be valuable. Always use a licensed, reviewed agent.

What is the TM30 and why does it matter?

The TM30 is a residence notification that your landlord, hotel, or property owner must file with immigration within 24 hours of your arrival at their property. It is required for most visa extensions and 90-day reports. Many hotels file this automatically, but if renting privately, ask your landlord to file it online via the immigration portal. Some immigration offices are strict about requiring the TM30 receipt for all services.

What is 90-day reporting?

Anyone staying in Thailand on a long-term visa (Non-B, Non-O, DTV extension, ED) must report their address to immigration every 90 days. This can be done in person at immigration, online via the immigration website, by mail, or through an agent. Online reporting is the easiest method and opens 15 days before the due date. There is no fee for 90-day reporting. Missing the deadline incurs a 2,000 THB fine.

Thailand Path Team|January 18, 2026

Most long-stay visas in Thailand require periodic extensions or border runs to maintain your legal status. Each visa type has different extension rules, costs, and requirements. This guide covers the extension process for every major visa type, from DTV extensions to retirement visa renewals to tourist visa extensions.

Key Takeaways

2Retirement visas (Non-O) renew annually at immigration for 1,900 THB
3Tourist visas can be extended 30 days once for 1,900 THB

5Immigration offices open Mon-Fri 8:30am-4:30pm — arrive early

DTV Visa Extension

The DTV allows 180-day stays per entry, which can be extended for another 180 days at your local Thai immigration office without leaving the country. Requirements for the extension include: your passport with at least 6 months validity remaining, TM6 departure card if you arrived by air (note that TM6 cards have been discontinued at some airports but may still be required at land borders), TM30 residence notification (your landlord, hotel, or property owner must file this within 24 hours of your arrival — many hotels do this automatically, but private landlords may need prompting), 1 passport photo (some immigration offices have photo services on-site for 100-200 THB), the 1,900 THB extension fee in cash (most offices only accept cash), proof of your qualifying activity such as an employment contract, freelance client contracts showing remote work, or course enrollment letters from Muay Thai camps or cooking schools, and bank statements showing 500,000 THB equivalent balance. Processing takes same day in Bangkok (Chaeng Wattana office, Building B) and Chiang Mai (Promenada mall location); allow 2-4 weeks in smaller provincial offices. You can extend twice per year effectively, giving you nearly 360 days of stay before needing a border crossing to reset. Apply 30-45 days before your current stay expires to maintain continuous legal status.

Retirement Visa Renewal

The Non-O retirement visa must be renewed annually at your local Thai immigration office. The financial requirements are strict: 800,000 THB in a Thai bank account (the funds must be seasoned for 2 full months before your renewal application date and must remain in the account for 3 months after approval — during the rest of the year, the balance must not drop below 400,000 THB) OR documented monthly income of at least 65,000 THB verified by embassy income letter or consistent bank transfers from overseas OR a combination of savings and documented income totaling 800,000 THB annually. Additional requirements include a medical certificate from any Thai clinic (100-300 THB for a basic check — some offices have stopped requiring this but bring one to be safe), TM30 residence notification receipt, the standard 1,900 THB fee, 2 passport photos, and a hand-drawn map to your residence (a curious but consistent requirement at most offices). Most retirees handle the entire renewal through an immigration agent (additional 3,000-5,000 THB) to avoid the paperwork hassle and early-morning queuing that can start at 5am at busy offices. Start the renewal process 30-45 days before your current extension expires to avoid any gap in your legal status, which could result in overstay fines.

Tourist & Other Extensions

Tourist visa (TR): extendable by 30 days once at any immigration office for 1,900 THB. Visa-exempt entry (60 days for most Western nationalities including US, UK, EU, Australia, and Canada): extendable by 30 days once for 1,900 THB. Non-B (business): extended annually with a letter from your employer, company registration documents, company tax records, social security documents, and the employer's guarantee letter, fee 1,900 THB. Education (ED): extended annually with school attendance records proving minimum 80% attendance, an official enrollment letter, academic progress reports, and sometimes photographs of you at the school, fee 1,900 THB. Marriage (Non-O): extended annually with 400,000 THB in a Thai bank seasoned for 2 months before application, your original Thai marriage certificate, photos of you and your spouse together at your shared home, maps to the residence, and sometimes witness interviews, fee 1,900 THB. Thailand Elite visa holders: no extensions needed since this is a 5, 10, or 20-year multiple-entry visa with 1-year stays permitted per entry. All extensions universally require a current TM30 residence notification receipt, recent passport photos, and the standard 1,900 THB government fee. Arrival cards (TM6) have been discontinued at most major airports but may still be required at land border crossings and some smaller airports.
