Thailand Long Stay: The 30-Day Extension Now Matters
Four days out, the argument is still about 60 becoming 30. The number that actually decides how long you get to stay is 1,900 — and most people have never filed for it.
Four Ministry of Interior notifications published in the Royal Gazette on 31 August 2026 take effect on 15 September 2026. The extension of stay itself is unchanged: 1,900 baht, 30 days, once per entry, filed on form TM.7 at an immigration office. What changes is how many people will need it. Four days to go.
Bangkok — From Monday, a Thailand long stay built on visa-free entry is a two-part document, not a one-part one. The stamp you collect at the airport is worth 30 days. The second 30 days — the ones that turn a month into something you can actually live in — have to be bought, in cash, in person, at an immigration office, on a form most visitors have never filled in.
That is the practical shape of the 15 September change, and it has had almost none of the coverage the headline day count got. Until Sunday, a visa-exempt arrival gets 60 days and can extend once for 30, making 90. From Monday, the same passport gets 30 days and can extend once for 30, making roughly 60. The extension has not changed. Its importance has.
What the extension of stay actually is
An extension of stay is not a visa. It is a permission granted inside Thailand, by the Immigration Bureau, on top of whatever entry you already hold. For visa-exempt arrivals and 60-day tourist visa (TR) holders it runs to 30 days, costs 1,900 baht, and is available once per entry. You cannot chain them. You cannot buy a second one by going to a different office.
Under the old 60-day exemption, most people never bothered. Sixty days covered a normal trip, and anyone living in Thailand for longer was usually on a proper route anyway. Under a 30-day exemption, the extension stops being a convenience and becomes structural: it is the difference between one month and two, and for a large slice of the Bangkok expat and Phuket digital nomad population it is now an unavoidable annual errand.
Nothing about the 1,900-baht extension changed on 15 September. It just went from an option most people ignored to the load-bearing wall of a 60-day stay.
The Thailand long stay document list, and the one that sinks people
The Thai visa requirement list for a TM.7 extension is short and completely unforgiving. Officers process hundreds a day and have no discretion to wave a missing item through.
- Passport, original, valid at least six months beyond your intended departure.
- Photocopies of the biodata page and of the page carrying your most recent Thai entry stamp.
- Form TM.7, completed in black ink before you arrive. Download it from the Immigration Bureau site rather than queuing for a blank one.
- Two passport photos, 35 × 45 mm, white background, taken within six months. Some offices still ask for 2-inch. Bring both.
- TM30 receipt — the residence notification your landlord or hotel is legally required to file when you check in.
- 1,900 baht in cash. Most offices do not take cards.
The TM30 is the one that sends people home empty-handed. Hotels usually have it ready at the front desk. Private landlords frequently have never filed one in their lives, and the consequence lands on you, not them. If you are renting in Thailand on a condo lease, ask for the TM30 the week you move in, not the morning of your appointment. Some offices will also want proof of onward travel or a bank statement; neither is universal, and having both removes an argument before it starts.
Provincial variation is real, and it is not a rumour
Same fee, same form, very different day. Bangkok's Division 1 office at Chaeng Watthana — Government Complex Building B, Laksi — opens at 08:30 and is the busiest in the country. Arrive by 08:00 for a queue number, or use the Immigration Bureau's online pre-registration and skip most of the wait. Chiang Mai living has the gentlest version of this: the office sits inside Promenada Resort Mall with free parking, and arriving before 10:00 usually means a same-day stamp by early afternoon. Phuket mirrors Bangkok's hours and Bangkok's queues from November to March, then empties out. Pattaya's Jomtien office is manageable outside peak months. Ko Samui and Krabi are quieter but thinly staffed — after midday, assume nothing.
Offices also differ on the soft stuff: which photo size they accept, whether they want the entry stamp copied front and back, how sympathetic they are about a landlord's missing TM30. None of that is written down anywhere official, which is precisely why the first extension of a Thailand long stay is the one to do carefully.
| Item | Until 14 Sept 2026 | From 15 Sept 2026 |
|---|---|---|
| Entry stamp | 60 days | 30 days (15 for two nationalities) |
| Extension of stay | +30 days, 1,900 baht, once | +30 days, 1,900 baht, once |
| Maximum per entry | About 90 days | About 60 days |
| Eligible passports | 93 countries and territories | 60 countries and territories |
| Land-border entries | No formal annual cap | Twice per calendar year, most nationalities |
| Stated purpose | Tourism, short business, urgent work | Tourism only |
The hidden costs, honestly counted
The fee is 1,900 baht. The actual cost of the trip is higher, and this is the part the agency blogs leave out. Budget a day off work, 200–600 baht of transport if you are not walking distance from the office, 200 baht for photos if you did not bring them, and the genuine possibility of a second visit if the TM30 is missing. Call it 2,500–3,500 baht and one working day, twice a year, if you are running a Thailand long stay on rolling visa-exempt entries.
Against that, compare the routes that remove the errand entirely. The DTV visa Thailand costs 10,000 baht for five years, 180 days per entry, with an in-country extension available — and since 31 August it must be filed at the mission covering your citizenship or legal residence, with a criminal record certificate attached. The Thailand retirement visa still runs on 800,000 baht banked or 65,000 baht a month for the over-50s, renewable annually. Both cost more up front than an extension. Neither asks you to queue at 08:00 with a cash envelope.
Thailand long stay deadlines, overstay and the things that follow you
Apply before your permitted-to-stay date expires, and preferably not on the final day — officers note last-minute filings. Overstay is 500 baht a day, capped at 20,000, payable at the airport, and beyond 90 days it triggers a re-entry ban that no agency can talk away. Thai immigration rules treat overstay as a record, not a receipt: it sits on your file the next time you apply for anything, including a work permit, a Non-O, or permanent residence years later.
One more piece of arithmetic worth doing this weekend. Anyone who enters on or before 14 September keeps the 60-day permission granted at the counter, plus the 30-day extension on top. Entering Sunday instead of Monday is worth a month.
Key takeaways — 11 September 2026
- The extension did not change; its role did. From 15 September it is the only way to turn a 30-day stamp into a two-month stay.
- 1,900 baht, cash, TM.7, once per entry. No chaining, no second office, no card payment at most counters.
- The TM30 is the failure point. Get the residence notification receipt from your landlord days in advance, not on the morning.
- Offices differ. Chaeng Watthana needs an 08:00 arrival or online pre-registration; Chiang Mai and Jomtien are materially calmer.
- Enter by 14 September and you keep 60 days plus the extension — about 90 in total.
- Two extensions a year cost more than a visa. Price the DTV or a Non-O against the days you are spending in queues.
The honest summary
Nobody is being thrown out. The cost of living in Thailand has not moved because of this, and for a two-week holiday none of it registers. What has happened is narrower and more irritating: the visa-free stamp has stopped being a long-stay instrument, and the 1,900-baht extension has been promoted from footnote to foundation. If your plan for next year involves more than sixty days at a stretch, that plan now contains a queue.
The people this bites hardest are the ones who never thought of themselves as having a visa problem — the six-months-a-year crowd, the Bangkok expat between contracts, the couple testing whether Hua Hin or Krabi is the best place to live in Thailand before committing. For all of them, an extension is a patch. A filed visa is a plan, and it makes everything downstream — opening a bank account, signing a lease, buying Thailand healthcare for foreigners — considerably less awkward.
