Extending Your Stay in Thailand: The 1,900-Baht Extension, Step by Step
With visa-free stays cut to 30 days in 2026, the once-optional extension trip to a Thai immigration office has become part of many itineraries. The good news: the standard 30-day extension is a routine, same-day process if you arrive prepared. Here's exactly how it works, what it costs, and the timing mistakes that turn routine into overstay.

What you can extend, and by how much
A visa-exempt entry can be extended once by up to 30 days, and a 60-day tourist visa (TR) can also be extended by 30 days. The fee is 1,900 baht, in cash, and approval is at the immigration officer's discretion. A Visa on Arrival generally cannot be extended, except when illness prevents you from travelling. The extension starts from the day your current permission expires, so applying a few days early costs you nothing.
Where to go
Any Thai immigration office handles tourist extensions — Bangkok's Chaeng Watthana division is the biggest, and offices in Chiang Mai, Phuket, Pattaya and the islands see tourists all day. Go early: popular offices distribute queue numbers from opening and busy days run out. Some offices accept online appointment booking; check your local office's channel.
The paperwork checklist
Passport (original), a completed TM.7 application form, one 4×6 cm photo, 1,900 baht cash, and photocopies of your passport photo page, current entry record and departure card data. Offices sell photocopies and photos on site, but the queue for the copy shop is time you don't need to spend.
The process on the day
Submit the paperwork, get photographed, wait for your number, receive the passport back with a new permitted-until date — typically one to three hours all in. Dress respectfully (shoulders and knees covered keeps things smooth), answer questions plainly, and check the new date before leaving the counter. Errors are fixable in the building, not from Koh Lanta.
When to apply
The sweet spot is within the last week of your current stay — early enough to survive a document hiccup, late enough that you're not burning extension days. Never plan the visit for your final day: one missing photocopy plus an office closing time equals an overstay stamp you'll carry in that passport for years.
Beyond the standard extension
Need longer than the extension gives you? Realistic routes: leave and return on a 60-day tourist visa, the DTV for remote workers (180 days per entry, 5-year validity), education visas with genuine study, or retirement visas at 50+. A second back-to-back tourist extension at the same office is generally refused — the 2026 enforcement climate has made 'creative' chains a bad bet.
Special cases worth knowing
Medical extensions (with a Thai hospital letter) and force-majeure extensions (canceled flights, closed borders) exist at the office's discretion. Parents of school-enrolled children and spouses of Thai nationals have their own categories with different paperwork. If your situation is genuinely unusual, a reputable Thai visa agent is worth the fee; if it's a normal holiday, you don't need one.
What the extension is worth, against the alternatives
Before queueing, it is worth seeing what you are choosing between. For a traveller who wants a few more weeks, these are the real options.
| Option | Extra time | Cost | Where |
|---|---|---|---|
| Extension of a visa-exempt entry | 30 days | 1,900 baht | Any immigration office, same day |
| Extension of a 60-day tourist visa | 30 days | 1,900 baht | Any immigration office, same day |
| Extension of a Visa on Arrival | Generally not allowed | Not applicable | Only if illness prevents travel |
| Leave and return visa-exempt | A fresh permission | Flights | A border, with scrutiny |
| Tourist visa applied for at home | 60 days from entry | Embassy fee | Before the trip |
The extension is almost always the cheapest and the least risky, and far cheaper than what an overstay costs. The row that looks cheap and is not is the fourth: a same-day bounce out and back is exactly the pattern the 2026 rules were written to discourage, and it is assessed by an officer who has seen it before.
The TM.7, field by field
The form is short, and three fields cause nearly all the corrections sent back across the counter.
| Field | What to write | Common error |
|---|---|---|
| Name | Exactly as in the passport | A shortened given name |
| Passport number | From the photo page | Confusing 0 and O |
| Arrival date and flight | From the entry stamp | Writing the departure date |
| Type of visa | "Visa exemption" if you entered visa-free | Writing "tourist" from habit |
| Address in Thailand | Where you are actually staying now | The hotel from week one |
| Reason for extension | "Tourism" is a complete answer | Over-explaining |
The last one deserves a note: a one-word answer is normal and expected. Long explanations invite questions, not sympathy.
What to bring, and what the office will sell you
Bring: passport, completed TM.7, one 4×6 cm photo, 1,900 baht in cash, and photocopies of the passport photo page, the entry stamp, and the departure-card record.
Nearly every office has a shop doing photos and photocopies. Using it is a queue inside a queue, on a morning where the queue you actually came for may run out of numbers. Twenty minutes at a copy shop the day before is the cheapest time you will ever buy.
Cash matters too — 1,900 baht, and offices are not reliably set up for cards.
How the new date is calculated
This is the part people get wrong in a way that costs them days.
The extension runs from the day your current permission expires, not from the day you apply. Permitted until 2 October, apply on 27 September, and the new date is 1 November — the extra thirty days are added to the end, not to the day you stood in the queue.
So applying early costs you nothing. Which makes the timing advice simple: go in the last week of your stay, not the last day.
What gets refused
Refusals are uncommon for ordinary tourists, and they cluster around a few situations. Worth knowing which side of the line you are on:
- A second consecutive extension on the same entry. The standard extension is once per entry; a second is generally refused.
- A pattern rather than a trip. Multiple entries, each extended to the maximum, over a long period, reads as living in Thailand on tourist permissions.
- Documents that do not agree. An address that does not match where you say you are staying, or an entry date that does not match the stamp.
- Applying after expiry. Then it is not an extension, it is an overstay, and it is a different counter with a fine.
Offices, in practice
| Office | Character | Worth knowing |
|---|---|---|
| Bangkok, Chaeng Watthana | The largest, and the busiest | Arrive well before opening; numbers run out |
| Chiang Mai | Steady tourist volume | Popular in high season; go early |
| Phuket | Tourist-heavy year round | Queues track the season |
| Pattaya (Jomtien) | High volume, used to tourists | Mornings are calmer |
| Island offices | Small, sometimes limited hours | Check opening days before travelling to one |
Wherever you go: dress as you would for a bank rather than a beach, bring a book, and expect one to three hours in total.
Before you leave the counter
Look at the new stamp before you walk away. Check the permitted-until date, and that it says what you expected. A mistake is fixable while you are standing in the building and a genuine problem once you are back on an island two ferries away.
Then photograph it, and put the new date in your phone with an alarm a week ahead. The extension solves this month's problem, and creates next month's deadline.
Planning around the new limits? Read the 2026 30-day visa-free rules before you book your dates.
