A tourist visa extension is one of the most straightforward things you can do at a Thai immigration office. It's also one of the most commonly botched, because people show up without a TM30, bring the wrong photo size, or turn up at 2pm expecting same-day processing. This guide covers every document, every fee, and the specific offices you need to go to.
One thing to get straight before anything else: a tourist visa extension buys you 30 extra days. That's it. You cannot chain multiple extensions. If you want to stay in Thailand beyond that, you'll need to exit the country or apply for a proper long-stay visa.
Book a free consultation if you're thinking beyond a 30-day extension and want to know your actual long-stay options.
Who Can Get a Tourist Visa Extension
Two categories of people can apply:
- Holders of a 60-day single-entry tourist visa (TR) — you can extend by 30 days, giving you 90 days total in-country.
- Visa-exempt arrivals (30-day stamp) — you can extend once for 30 days, giving you 60 days total. This applies to most Western passport holders, Australians, Canadians, Japanese, and others on the visa-exemption list.
What you cannot do: extend a visa-exempt stamp more than once in the same trip. Thai immigration is well aware of the pattern and officers do exercise discretion. If your passport shows a long pattern of consecutive short stays, you may be questioned or denied.
The Exact Documents You Need
Show up without any one of these and you'll be turned away. Immigration officers are not flexible on missing documents — they process hundreds of extensions a day and have zero incentive to make exceptions.
- Passport — original, valid for at least 6 months from your intended departure date
- Passport photocopy — the biodata page AND the page with your most recent Thailand entry stamp. Both pages, both sides if your stamp is on the back.
- TM7 form — the application for extension of temporary stay. Available at the immigration office or downloadable from the Thai Immigration Bureau website. Fill it out in black ink before you arrive.
- One passport-sized photo — 4x6 cm, white background, taken within the last 6 months. Some offices accept a 2-inch photo. Bring both sizes if you can.
- TM30 receipt — this is your residence notification. Your landlord or hotel is legally required to file a TM30 when you check in. Ask them for a printed copy. Many hotels have it ready; private landlords often don't file it at all, which is your problem on extension day.
- ฿1,900 THB cash — exact fee, no card payments at most offices. Bring the exact amount or slightly more. There are ATMs near most immigration offices.
Some offices will also ask for proof of onward travel (a flight booking) or proof of funds. It's not universally required, but having a bank statement showing a reasonable balance removes any friction before it starts.
Step-by-Step: How the Extension Process Works
Step 1 — Get your TM30 sorted the night before
If you're staying in a hotel, ask the front desk for your TM30 receipt before you leave. If you're in a private rental, WhatsApp your landlord that evening. Do not assume this is handled. Missing TM30 is the single most common reason people leave an immigration office empty-handed.
Step 2 — Arrive early
Bangkok's Chaeng Watthana office opens at 8:30am. Be there by 8:00am to queue for a number. Same-day processing is standard, but afternoons at busy offices can push your stamp to the next working day. Provincial offices in Chiang Mai and Phuket are generally faster, but still arrive before 10am.
Step 3 — Get a queue number at the information desk
Tell the officer you're there for a tourist visa extension. They'll direct you to the right queue and may do a quick document check on the spot. If something's missing, they'll tell you before you wait two hours.
Step 4 — Submit your documents at the counter
Hand over your passport, TM7 form, photocopies, photo, TM30 receipt, and ฿1,900. The officer will review your documents, take your fee, and give you a receipt with a collection time.
Step 5 — Collect your passport
Most same-day approvals have passports ready in the afternoon (typically 1–3pm depending on the office and how busy it is). Your new stamp will show your updated permitted-to-stay date. Check it immediately before you leave the building — typos on stamp dates do happen.
Immigration Office Locations by City
Bangkok — Chaeng Watthana
The main Bangkok immigration office is at Government Complex Building B, Chaeng Watthana Road, Laksi. It's the largest and busiest in the country. Take the MRT to Chaeng Watthana Government Complex station (the Purple Line extension). Office hours are Monday–Friday, 8:30am–4:30pm. Lunch break 12:00–1:00pm. It does not process on public holidays.
Expect long queues. The online pre-registration system (through the Immigration Bureau website) lets you book a time slot, which cuts your wait significantly. Use it.
Chiang Mai — Promenada
The Chiang Mai Immigration Office is inside Promenada Resort Mall, 300/302 Moo 5, Canal Road (Klong Chonlaprathan), Nong Pa Khrang. Hours: Monday–Friday, 8:30am–4:30pm. Much calmer than Bangkok. Arrive before 10am for smooth same-day service. Parking is free in the mall.
Phuket — Phuket Town
Located at Phuket Immigration, Phuket City, near the Provincial Hall area on Phuket Road. Hours mirror Bangkok. Phuket sees heavy tourist traffic in high season (November–March), so queues can rival Bangkok during those months. Off-season visits are considerably quicker.
Pattaya — Jomtien
The Pattaya Immigration Office is at 75/64 Moo 5, Jomtien, near Soi 5. Popular with the large expat community along the Eastern Seaboard. Same hours, same documents. Generally manageable queues outside of peak months.
Ko Samui
The Ko Samui Immigration Office is in Nathon, the main town on the island. Smaller, quieter, but also less staffed. Arrive early and don't assume same-day processing if you're there after noon.
Other Locations
Immigration offices also operate in Hua Hin, Krabi, Hat Yai, Udon Thani, and other provincial capitals. If you're outside the major tourist areas, check the Thai Immigration Bureau's official website for the nearest office. The rule is the same: in-person only, same documents, same ฿1,900 fee.
The Honest Limits of a Tourist Visa Extension
Thirty days is a short runway. If your goal is to spend 3–6 months in Thailand working remotely, a tourist extension isn't a strategy — it's a delay. Eventually you'll need to either exit and re-enter (with diminishing immigration goodwill) or switch to a proper long-stay visa.
The most practical pivot for remote workers who can't meet the DTV's ฿500,000 financial requirement is the Multiple Entry Tourist Visa (METV), which requires showing roughly ฿40,000 (~$1,300 USD) in funds and gives you 6 months of in-out flexibility. For people who do meet the ฿500,000 threshold, the Digital Nomad Visa (DTV) is a far better deal: 5-year validity, 180 days per entry, no more queuing at Chaeng Watthana.
Retirees have their own path. If you're over 50 and want to stop doing this dance entirely, a Thai Retirement Visa gets you a renewable 1-year stay with far less hassle per year.

What Issa Does Differently
Most people extending a tourist visa don't need a lawyer. The ฿1,900 extension is a DIY process — this guide gives you everything to do it yourself.
Where Issa's value becomes real is when you're thinking about what comes next. The clients who come to us are typically sitting in a Chiang Mai café after their second extension, realizing they've been in Thailand four months and they want six more — but they can't legally stay without exiting or switching visas. That's a planning problem, not a paperwork problem.
Issa handles the planning. Our app collects your documents in about 15 minutes. Our legal team then reviews your specific financial picture, employment status, and travel history to tell you exactly which visa you qualify for and structures your application around your actual situation. Freelancers with irregular income, FIFO workers, business owners with company accounts — these are not edge cases for us, they're our daily bread.
The guarantee matters here too. If your application is rejected because of something we missed, we refund both our service fee and your government embassy fees. No partial refunds, no asterisks. That's the actual offer.
| Factor | Issa Compass | Traditional Lawyer | DIY |
|---|---|---|---|
| Document collection | ~15 min via app | Days of email threads | On you entirely |
| Financial pre-screening | Manual review before submission | Varies by firm | None |
| Rejection protection | 100% refund incl. govt fees | Rarely offered | You absorb all costs |
| Post-approval support | 90-day report tracking, TM30, alerts | Not included | None |
| Complex cases (freelance, FIFO, crypto) | Structured by legal team | Expensive, slow | High rejection risk |
After Your Extension: The 90-Day Report Obligation
If you're holding a long-stay visa and have been in Thailand for 90 consecutive days, you have a separate legal obligation: filing a 90-day report with immigration. This is not the same as a visa extension and is commonly confused. Tourist visa holders on short extensions don't typically hit this threshold, but anyone transitioning to a Non-B, retirement visa, or DTV absolutely does.
The Issa app tracks your 90-day report due date and alerts you before it's late. A missed 90-day report carries a ฿2,000 fine and creates a complication the next time you're at an immigration counter.
Quick Reference: Extension Rules at a Glance
- Extension length: 30 days only, no exceptions
- Fee: ฿1,900 THB cash
- Number of extensions: One per entry
- Application deadline: Must apply before your current permitted stay expires. Do not wait until the last day — officers will note it.
- Overstay fine: ฿500 per day, paid at the airport on departure. Over 90 days of overstay triggers a re-entry ban.
- Processing time: Same-day at most offices if you arrive before noon
- Accepted payment: Cash only at most offices
For anything beyond a one-time extension, the math changes fast. Talk to an Issa visa specialist to figure out whether a DTV, METV, or another long-stay visa is your actual next move.
