Thailand’s visa-exempt entry policy is one of the most traveler-friendly rules in Southeast Asia — but it’s also widely misunderstood. Show up at immigration with vague intentions and you risk fines, blacklists, or a shortened stay. Get it right, and you can stretch your 30-day entry into a seamless multi-month adventure legally and affordably.
This guide covers everything you need to know for 2026: how the visa-exempt rule actually works, the TM28 accommodation notification requirement, the step-by-step extension process, current fees, hard rules you cannot break, and insider tips from long-term travelers.
How Thailand’s Visa Exempt Entry Works
Thailand grants visa-exempt entry to passport holders from 64 countries (as of early 2026). Under this arrangement, you can enter Thailand without a pre-obtained visa and receive a stay permit of 30 days upon arrival at any international checkpoint — including airports (Suvarnabhumi, Don Mueang, Phuket, Chiang Mai) and land borders.
This is not a “visa on arrival” in the traditional sense. The 30-day stamp is a permit to stay, not a visa. You cannot extend it indefinitely, and the rules differ slightly depending on your entry point:
| Entry Point | Typical Stamp Duration | Notes |
|---|---|---|
| Suvarnabhumi Airport (BKK) | 30 days | Most common, smoothest process |
| Don Mueang Airport (DMK) | 30 days | Budget airlines often busier |
| Phuket International Airport (HKT) | 30 days | Popular for island arrivals |
| Chiang Mai Airport (CNX) | 30 days | Northern gateway, moderate queues |
| Land borders (e.g., Aranyaprathet) | 15–30 days (varies) | Border crossings sometimes grant fewer days |
For air arrivals, the standard is consistently 30 days. For land arrivals, Thai immigration officers have discretionary authority and may stamp fewer days — often 15 or 20 — especially at busy borders.
Citizens of 18 select countries (including the US, UK, Canada, Australia, and most EU nations) can receive an automatic 60-day extension at certain ports, though this is applied on a case-by-case basis and is not guaranteed at all entry points.
Your stamp includes a departure deadline printed clearly in your passport. Missing it — even by one day — triggers overstay fines starting at THB 500 per day (approximately USD 14 at current exchange rates).
Platform Tip: Before booking your flights, check current entry requirements and airline-specific policies via Skyscanner to compare routes and verify the latest rules for your nationality.
The TM28 Notification — What It Is and Why You Must File It
Here is the step most first-time visitors skip: TM28, the Notification of Residence Where Foreigners Stay. Under Thai immigration law, every foreigner staying in Thailand — even on a visa-exempt entry — must notify the authorities within 24 hours of arriving at any accommodation (hotel, hostel, apartment, or private residence).
This is not optional. It is a legal requirement under Section 37 of the Thai Immigration Act.
Who Must File TM28?
- Every foreigner entering Thailand on any status (visa-exempt, tourist visa, long-term visa)
- Filed by the accommodation provider (most hotels and hostels do this automatically)
- If staying in private accommodation (Airbnb, friend’s apartment, your own rental), you are personally responsible for filing
How to File TM28
- Online (preferred): Visit thaievisa.go.th and complete the TM28 online notification form within 24 hours of check-in.
- Paper form at local immigration: Obtain a TM28 form, complete it with your accommodation address, passport details, and intended length of stay, then submit to the nearest immigration office.
- Through your hotel/hostel: Ask the property if they file TM28 on your behalf. Reputable hotels in Bangkok, Chiang Mai, and Phuket almost always handle this.
Penalties for Missing TM28
Failure to notify can result in:
- THB 1,600–5,000 fine for non-reporting
- Complications during visa extensions or border runs
- Potential issues when applying for future Thai visas
Keep a printed copy of your TM28 acknowledgment or the hotel’s stamp-receipt in your passport at all times.
The Immigration Extension Process — Step by Step
If 30 days isn’t long enough, you can apply for a 30-day extension at any Thai immigration office. This is processed under Section 35 of the Immigration Act and is the standard, legal method to extend a visa-exempt stay.
Where to Apply
The main immigration offices handling extensions are:
| Location | Address | Notes |
|---|---|---|
| Bangkok (Chaeng Wattana) | 120 Chaeng Wattana Road, Lak Si | Largest office, long queues |
| Bangkok (Suvarnabhumi) | Level 2, Passenger Terminal | Convenient for airport arrivals |
| Phuket | 4821 Phuket Road | Popular with island visitors |
| Chiang Mai | 152 Charenmuang Road | Manageable wait times |
| Pattaya | 89 Moo 10, Naklua Road | Southern corridor applicants |
Appointments can sometimes be booked in advance through Klook or the official immigration website, which can save hours of waiting.
Required Documents
- Passport (valid for at least 6 months beyond the intended stay)
- TM3 form — Application for Extension of Temporary Stay (available at immigration offices)
- One passport-sized photograph (4×6 cm, taken within 6 months)
- Copy of passport bio page and the page with your current entry stamp
- TM28 acknowledgment or accommodation proof (hotel booking confirmation, lease agreement)
- Extension fee — see Costs & Fees section below
Step-by-Step Process
Step 1 — Arrive Early Immigration offices open at 08:30 and queues build quickly. Arrive by 08:00–08:15 for the best chance of being served the same day.
Step 2 — Collect and Fill Forms Take a TM3 form from the counter. Use the provided pens and tables. Be precise — illegible handwriting or incorrect information causes rejections.
Step 3 — Submit at the Processing Window Hand your documents to the officer. They will review your passport, current stamp, and TM28. Expect questions about your accommodation and why you need an extension.
Step 4 — Pay the Fee Once approved, pay at the adjacent cashier window. You will receive a receipt.
Step 5 — Collect Your Extended Stamp Return to the processing window with your receipt. The officer will add 30 additional days to your passport stamp.
Pro Tip: Many travelers combine their immigration visit with other errands. Nearby Klook experiences in the same city make a full day of it — visit the Grand Palace in the morning, then handle your extension before lunch crowds arrive.
Costs and Fees — 2026 Breakdown
Understanding the fee structure prevents surprises. All fees below are current as of early 2026.
Extension Fees
| Fee Type | Amount (THB) | Approx. (USD) | Notes |
|---|---|---|---|
| 30-day extension | 1,900 | ~53 | Standard processing |
| Rush extension (same day) | 2,500–3,800 | ~70–106 | Requires supervisor approval, not always available |
| Overstay fine (per day) | 500 | ~14 | Charged at departure if you overstay |
Related Costs to Budget
| Cost Item | Amount (THB) | Approx. (USD) | Notes |
|---|---|---|---|
| TM28 online filing | Free | Free | No charge for online notification |
| Passport photo | 100–200 | ~3–6 | Available at photo shops near immigration offices |
| Transportation (Bangkok) | 50–200 | ~1.50–6 | BTS/MRT to Chaeng Wattana, or Grab |
| Accommodation proof | Varies | Varies | Hotel booking or lease; be ready to show 30+ days |
Long-Term Alternatives — Cost Comparison
If you’re planning to stay 60+ days, the economics shift. Consider whether a tourist visa or Thai Elite visa makes more sense than repeated 30-day extensions.
| Option | Cost | Duration | Best For |
|---|---|---|---|
| Visa-exempt + 30-day extension | THB 1,900 (~USD 53) per cycle | 60 days max (2 cycles) | Short-term visitors staying ≤2 months |
| 60-day tourist visa | THB 1,000 (~USD 28) application + extension fees | 60 days + 30-day extension | Travelers planning 60–90 days |
| Thailand Elite visa (5-year) | THB 21,000–50,000 (~USD 600–1,400) | 5 years, unlimited entries | Long-term residents, digital nomads |
| Non-Immigrant B (business) | THB 3,000–10,000 | 90 days–1 year | Those working or investing in Thailand |
Budget Tip: For mid-length stays, booking accommodations with Booking.com often includes free cancellation, which satisfies the accommodation proof requirement for TM28 and immigration without financial risk.
Critical Rules — What You Cannot Do
Thailand’s immigration system is relatively forgiving for honest travelers, but certain violations carry severe penalties. Know these hard rules before you arrive:
1. Overstaying Is a Criminal Offense
Overstay fines of THB 500/day accumulate rapidly. Beyond 90 days of overstay, you face a 2-year ban. Beyond 1 year, a 5-year ban. Immigration officers at departure scan every passport — unpaid fines will be collected, and repeated overstays are flagged in a shared database across ASEAN nations.
2. You Cannot Work on a Visa-Exempt Entry
Visa-exempt status is strictly for tourism. Engaging in any form of employment — even remote work for a foreign employer — constitutes a legal violation. If you plan to work in Thailand, you need a proper Non-Immigrant B visa and a work permit.
3. 90-Day Reporting Is Mandatory (Even During Extensions)
If you stay more than 90 days cumulative in Thailand within a 180-day period, you must file a 90-day report (TM47) every 90 days, either online or in person at immigration. Extensions do not cancel this requirement.
4. Do Not Rely on Border Runs
Some agencies promote “border runs” (leaving Thailand briefly and re-entering to reset the 30-day clock) as a cheap extension strategy. This technique has become significantly riskier since 2024. Thai immigration now actively scrutinizes consecutive entries and can deny re-entry if they believe you’re using it as a visa workaround rather than genuine tourism. The fine for abuse is denial of entry, not just a warning.
5. Address Changes Require TM28 Updates
Every time you move to a new accommodation, you must file a TM28 change notification within 24 hours. Failing to update your address when changing hotels is one of the most common, avoidable violations.
Extension Tips — Advice from Long-Term Travelers
Plan Your Extension Window Early
Immigration offices are least crowded on Tuesday through Thursday mornings. Mondays and Fridays are packed. If you’re near the end of your current stamp, don’t wait until the last day — processing can take 2–4 hours, and you don’t want to risk missing your departure time.
Use the Online TM28 System
The online TM28 notification at thaievisa.go.th has been significantly improved since 2024. Filing online is faster, creates a digital record, and eliminates the risk of a hotel misfiling your paper notice. Use it even if your hotel says they’ll handle it.
Separate Your Accommodation Proof
If you’re staying in multiple locations, keep a combined itinerary showing all bookings. Immigration officers want to see a coherent plan, not a chaotic series of last-minute hostels.
Keep Multiple Copies of Everything
Scan every document — passport pages, entry stamps, TM28 acknowledgments, extension receipts — and store them in cloud storage (Google Drive, iCloud) and a secondary USB drive. Lost paperwork is a solvable problem; lost digital copies are a disaster.
Know Your Rights at the Immigration Window
Immigration officers can be brusque. Remain calm and polite. If you believe you’ve been treated unfairly, ask to speak with a supervisor (you can say: “I would like to speak with an officer in charge, please”). Written complaints can be filed at the main immigration office or online.
Consider the 60-Day Visa Route for 2–3 Month Stays
If you’re planning 60–90 days, a tourist visa from a Thai embassy or consulate before arrival is cleaner and often cheaper than two consecutive 30-day extensions. You apply at any Thai embassy; processing takes 2–5 business days and costs less than two extension fees combined.
Frequently Asked Questions
Can I extend my visa-exempt stay more than once?
Yes, you can apply for a 30-day extension at the end of your initial 30-day visa-exempt period. However, Thai immigration reviews each application individually, and repeated extensions without a clear, legitimate reason can raise flags. For stays longer than 60 days, consider applying for a tourist visa or longer-term visa category instead.
What happens if I miss the 90-day reporting deadline?
Missing a 90-day report (TM47) results in a fine of THB 1,600–4,000 upon your next immigration interaction. The fine increases for longer delays. You can file late reports at any immigration office — bring your passport and any proof of your address history to explain the delay.
Is it safe to do a border run to reset my stay period?
Border runs have become significantly riskier as of 2024–2025. Thai immigration now monitors entry-exit patterns closely. If you exit and re-enter within days or weeks, officers may deny you entry, flag your passport, or grant only a reduced stay (15 days instead of 30). A border run is no longer a reliable or recommended strategy for extending a visa-exempt stay.
Can I apply for a Thai visa while already in Thailand on visa-exempt entry?
In most cases, no. You generally cannot convert a visa-exempt stamp to a long-term visa while inside Thailand. You must apply for long-term visas (tourist visa, Non-Immigrant, Elite, etc.) at a Thai embassy or consulate outside Thailand. Plan accordingly before your trip.
How long does the extension process take?
On a typical weekday, expect 2–4 hours from arrival at the immigration office to collecting your extended stamp. Tuesdays through Thursdays are fastest. Mondays and Fridays can take most of the day. Booking a timed appointment through Klook or the official immigration portal can significantly reduce your wait.
Does the TM28 requirement apply if I’m staying in an Airbnb?
Yes. Any private rental accommodation — Airbnb, Booking.com apartment, friend’s apartment, condo — requires TM28 notification by the guest. You can file it online at thaievisa.go.th within 24 hours of check-in. Your host may or may not be aware of this requirement, so take responsibility for it yourself to avoid any issues.
