Extend Your Thailand Visa Exemption: Step by Step

You landed in Thailand, got your visa exemption stamp, and now you are running out of days. Maybe you spent too long in Chiang Mai learning to make khao soi from scratch, or the islands pulled you south and you lost track of the calendar entirely. It happens to everyone. The point is: your stamp is about to expire and you are not ready to leave.

You may not have to. Since 15 September 2026, the visa exemption gives most eligible passports 30 days, and you can ask Thai immigration for an extension of up to 30 more days. You apply inside Thailand, at an immigration office, with form TM.7 and a 1,900 THB fee. No embassy visit and no advance application. The catch: the extension is at the immigration officer's discretion, so it is not automatic, and you should plan as if a refusal is possible.

This guide is the practical companion to our broader visa guides. No "which visa should I get" debates. Just the steps to extend your visa exemption, what to bring, where to go, and how to avoid the mistakes that waste your morning.

Who Can Extend (and How Much Time You Get)

Not every entry type works the same way. Here is the breakdown under the current rules.

Visa Exemption -- Air Entry

You received: 30-day stamp at the airport
Extension available: Up to 30 additional days, at the officer's discretion
Total stay: Up to 60 days
Cost: 1,900 THB

This is the most common scenario. If you flew into Thailand on a passport from one of the 60 countries and territories on the 30-day exemption list, you got 30 days stamped into your passport. An approved extension takes you to a maximum of 60 days on that entry. The old 60-day exemption, which could stretch to 90 days, was repealed on 15 September 2026.

Admitted before 15 September 2026? You keep the stay you were granted on arrival. Check the "admitted until" date in your passport rather than counting from the new rules.

Visa Exemption -- Land Entry

You received: 30-day stamp at a land border
Extension available: Up to 30 additional days, at the officer's discretion
Total stay: Up to 60 days
Cost: 1,900 THB

Air and land entries on the exemption now give the same 30 days. The difference is the number of land entries: on the exemption you can generally enter overland no more than twice per calendar year. Nationals of Malaysia, Brunei, Indonesia and Singapore are not limited in this way. The application process and documents for an extension are the same whichever way you came in, and if you are unsure whether your land stamp can be extended, ask at the immigration office rather than assuming.

Visa on Arrival (VOA)

The current Visa on Arrival list covers passports from Azerbaijan, Belarus and Serbia. The VOA has given 15 days, but the 2026 notice does not restate the stay length or the extension, so confirm both with the Thai embassy before you travel and ask immigration in Thailand before your stamp runs out. See the Visa on Arrival guide.

Other Entry Types

This guide covers visa exemption holders. Other entry types follow their own rules:

Bilateral agreements. Some nationalities enter under separate agreements that give 90, 30 or 14 days. Those agreements still apply. Ask immigration whether your stay can be extended.
Tourist Visa (TR). A TR gives 60 days from arrival and can be extended by up to 30 days, again at the officer's discretion, for the same 1,900 THB fee.
Transit, diplomatic and other visas. These follow separate procedures. Ask the issuing embassy or immigration.

What to Bring: The Complete Checklist

Get everything on this list ready before you go to immigration. Showing up without one item usually means going away and coming back. It is the most common way people lose a morning.

Your Checklist (Screenshot This)

Passport (original) -- They hold it during processing and return it with the new stamp
Completed TM.7 form -- The "Application for Extension of Temporary Stay in the Kingdom"
A recent photograph -- Bring a printed passport-style photo, not one on your phone
Photocopies of your passport pages -- At least the bio page (with your photo and details) and the page with your most recent Thailand entry stamp
1,900 THB -- The extension fee
Proof you will leave -- A confirmed onward or return ticket is worth carrying

Immigration may ask for extra supporting documents depending on your situation, such as where you are staying. If an officer asks for something not on this list, it is quicker to get it than to argue.

Sign your photocopies. Offices commonly ask for every copy to be signed. It costs you ten seconds at the hostel and can save you a trip back to the counter.

Costs Breakdown

The official fee is 1,900 THB. On top of that you may pay a little for a printed photo and photocopies if you do not already have them. They cost little next to the fee.

Compare that to a last-minute flight to a neighbouring country for a border run, and the extension is often the simpler deal, as long as the officer approves it.

Step-by-Step: What Happens at the Immigration Office

Here is how your visit usually unfolds, from arrival to walking out with your new stamp. Offices differ, so treat this as the typical shape rather than a script.

Step 1: Arrive Early

Queues build through the morning, especially at busy city offices. Arriving soon after opening gives you the best chance of finishing the same day. Check the opening hours of the office you plan to use before you go, because they vary and change.

Step 2: Take a Queue Number

Walk in and look for the queue number machine or the information desk near the entrance. Ask for "extension of stay." At smaller offices there might just be a line -- join it. Some offices have separate windows for different visa types. If you are unsure, ask the staff at the door. They deal with confused foreigners all day and will point you in the right direction.

Step 3: Submit Your Documents

When your number is called, go to the counter and hand over everything: your passport, completed TM.7 form, photocopies and photo. The officer will check your documents, look up your passport in their system, and may ask a question or two about your plans ("Where are you staying?" "When are you leaving Thailand?"). Answer plainly and have your onward ticket ready to show.

If something is missing, they will tell you what you need. Do not panic. Many immigration offices have photocopy and photo shops close by, because people forget things all the time. Step out, get what you need, and come back.

Step 4: Wait

This is the boring part. You sit in a waiting area while the officer processes your application and works through the applications ahead of yours. How long it takes depends on the office and the day, and big-city offices are usually the slowest.

Bring a book, a charged phone, downloaded podcasts, or whatever keeps you sane in a plastic chair.

Step 5: Photo and Biometrics

Some offices take a photo at the counter, and some take fingerprints. It is quick. Not every office does it.

Step 6: Pay 1,900 THB

You will be directed to pay the 1,900 THB fee. Bring the fee in cash to be safe, and keep the receipt with your travel documents.

Step 7: Collect Your Passport and Check the Stamp

If the extension is approved, your passport comes back with a new stamp showing your new "admitted until" date. Check it immediately at the counter before you walk away:

Is the new date the one the officer told you?
Is the stamp legible?
Does anything look wrong?

If there is an error, tell the officer right now while you are standing at the counter. Fixing a stamp mistake days or weeks later is a completely different problem.

That is the entire process. Walk out, enjoy your extra time.

The TM.7 Form: What Each Field Means

The TM.7 is the official form for extending a temporary stay. You can pick one up at the immigration office. Filling it out before you reach the counter saves you scrambling with a chained pen that barely works.

For our complete field-by-field walkthrough with examples, see the dedicated TM.7 form guide. Here is the quick version:

The Fields That Trip People Up

Date format: Write dates day first: DD/MM/YYYY. If your birthday is March 15, 1998, write 15/03/1998 -- not 03/15/1998. This is one of the most common mistakes on the form.

"Date of Arrival": The date you entered Thailand on your current entry. Check the stamp in your passport and copy it exactly. Do not guess.

"Permitted to Stay Until": Your current expiry date, stamped in your passport as "admitted until." Copy that date.

"Present Address in Thailand": Write the full address of where you are currently staying -- hotel or hostel name, street, district, province, postal code. "Chiang Mai" is not enough. If you do not know the address, check a map app for your accommodation or ask at reception for a business card.

"Period of Extension Requested": On the visa exemption, the most you can ask for is 30 days. Do not write 60 or 90: those figures belonged to the repealed scheme.

Signature: Sign the form. Then sign your photocopies. Then double-check that you signed the form. Unsigned documents get sent back and you lose your place in line.

Immigration Offices by City

You apply at the immigration office that covers the place you are staying. Where you are when your stamp runs low matters: a quieter office can save you hours. Check the current address and opening hours of each office before you go, because offices move and hours change.

Bangkok: Chaeng Wattana Government Complex

Bangkok's main immigration office is at the Chaeng Wattana Government Complex. It is also the busiest office in the country, so expect a long wait even if you arrive early.

Getting there: Taxi or Grab is the simplest way
Photos and copies: Get them done before you arrive if you can

If you are spending time in Bangkok and your extension date is flexible, consider doing it in your next destination instead. A smaller office usually means a calmer morning.

Chiang Mai

Chiang Mai is the classic place to extend for backpackers in the north, and the office handles a steady flow of long-stay visitors and digital nomads. Go early, bring everything on the checklist, and expect a queue in high season.

Getting there: Songthaew or Grab from the old city
Photos and copies: Bring them with you to avoid a detour

Phuket: Phuket Town

A standard government office experience. Moderate queues, nothing remarkable, gets the job done. Beach areas are some distance away, so plan the trip into town.

Getting there: Songthaew from the beaches or Grab
Photos and copies: Bring them with you

Koh Samui: Nathon

A small island office. Being on an island limits the crowd compared with the big cities.

Getting there: Songthaew to Nathon from anywhere on the island
Photos and copies: Bring them with you

Koh Phangan: Thong Sala

Usually quieter, but beware: around Full Moon Party dates the island fills with backpackers, and plenty of them discover at the same time that their stamp is about to expire. Go mid-cycle when the island is calmer.

Getting there: Songthaew or scooter to Thong Sala
Photos and copies: Bring them with you

Pattaya: Jomtien

Handles a large volume of expats and tourists. Not the worst, not the best. A standard immigration morning.

Getting there: Baht bus or Grab from central Pattaya
Photos and copies: Bring them with you

Krabi: Krabi Town

A smaller office that serves the Krabi, Railay and Ao Nang crowd. Usually less busy than Phuket.

Getting there: Songthaew or Grab from Ao Nang
Photos and copies: Bring them with you

The Rule: Smaller Office = Faster Extension

If you have any flexibility in your travel plans, time your extension for a smaller, quieter office. Provincial offices away from the tourist hubs tend to have shorter queues than Bangkok. Plan your route so that you reach one with time to spare before your stamp expires.

Photos and Photocopies: Where to Get Them

You will need a recent photo and photocopies of your passport pages. Here is how to sort this out without stress.

Forgot something?

Where to get photos and copies

Passport Photos

Bring a recent, printed passport-style photo. If you are not sure your photos from home will be accepted, get a fresh set taken in Thailand by a shop that knows what immigration asks for.

Where to get them:

Photo shops near immigration offices: Many offices have one within walking distance, because so many applicants need photos.
Photo booths in shopping malls: Look for the automatic photo booths in malls and department stores.
Photo studios in town: Any studio that does passport photos can help; tell them it is for an immigration extension.

Photocopies

You need copies of your passport bio page and your Thailand entry stamp page. Copy any other page the office asks for.

Where to get them:

Near the immigration office: Copy shops often cluster close to the office. They usually know which pages you need -- just hand them your passport.
Convenience stores and print shops: Many have a copy machine.
Your hotel or hostel: Many accommodations will make copies for you if you ask.

Remember to sign your photocopies before submitting.

When to Go: Timing Your Extension

Apply Well Before Your Stamp Expires

Give yourself a buffer. Applying early leaves room if something goes wrong -- the office is closed for a public holiday, you forgot a document, the system is down, or the officer refuses the extension and you need to arrange your departure. Ask the office how the new date is calculated when you apply.

Do Not Wait Until the Last Day

Picture it: someone walks into immigration on the day their stamp expires, discovers they forgot their photo, and is overstaying by the time they get back with one. Or the office is closed for a Thai public holiday they did not know about. Or the extension is refused.

Any of these can leave you overstaying, and overstaying costs 500 THB per day, up to a maximum of 20,000 THB. Longer overstays bring re-entry bans of one year or more. None of this is worth the risk when you could have gone a week earlier.

Check for Thai Public Holidays

Government offices close on Thai public holidays, and Thailand has a lot of them. Check the holiday calendar and the office's opening hours before you plan your visit, and avoid turning up near closing time.

What If You Get Denied?

The extension is discretionary. The rules allow "no more than 30 days" on top of the exemption, and the immigration officer decides whether to grant it. Complete documents and a clear plan to leave help, but nothing guarantees approval.

Red Flags That Can Lead to Denial

Too many entries: If your passport shows a pattern of back-to-back entries over months or years, immigration may suspect you are living in Thailand on tourist entries rather than genuinely travelling.
Suspicion of working: You cannot work on the visa exemption. If immigration has reason to believe you are working in Thailand, they can refuse the extension and may investigate further.
History in Thailand: Previous overstays, arrests or blacklist entries will complicate your application.
Passport problems: A passport close to expiry, damaged, or with information that does not match the form.
No plan to leave: Not being able to show when and how you will depart.

Approval is discretionary

What can get an extension refused

If refused, you must leave by the date already in your passport.

What Happens If You Are Denied

If the extension is refused, you must leave Thailand by the date already in your passport. Ask the officer to confirm that date before you walk away.

If this happens, your options are:

Leave Thailand before your stamp expires
Leave and come back on a new entry later. A new exemption entry gives 30 days (by air or land) and is at the officer's discretion at the border, and land entries count toward the twice-a-year limit
Apply for a proper visa, such as a Tourist Visa, through the Thai e-Visa system before you return

After the Extension: Your New Timeline

Once you walk out of immigration with your new stamp, here is where you stand:

Air Entry Extension

Original entry: 30 days
Extension: Up to 30 days
Total: Up to 60 days
What is stamped: Your new "admitted until" date

Land Entry Extension

Original entry: 30 days
Extension: Up to 30 days
Total: Up to 60 days
What is stamped: Your new "admitted until" date

VOA Extension

Original entry: 15 days so far; confirm with the Thai embassy
Extension: Ask immigration before your stamp runs out

You Cannot Extend Again

On the visa exemption, the most you can get is 60 days in total: the 30 you received on arrival plus an extension of up to 30. When your extended stay is about to expire, your options are:

Leave Thailand. Fly to Vietnam, Malaysia, Laos or anywhere else. Many backpackers use this as a chance to explore a neighbouring country. Land crossings between Thailand and Cambodia are suspended, so do not plan an overland exit that way.
Leave and re-enter. A new exemption entry gives 30 days whether you fly or cross by land, not 60, and the officer at the border decides whether to admit you. Frequent back-to-back entries draw questions, and land entries are generally limited to two per calendar year.
Get a tourist visa. A Tourist Visa (TR) gives 60 days from arrival and can be extended by up to 30 days at the officer's discretion. Apply through the Thai e-Visa system before you travel.
Consider the DTV. If you are working remotely for clients outside Thailand, the Destination Thailand Visa gives 180 days per entry and can be extended once by 180 days. It is the best option for long-term stays.

Extension vs Border Run: Which Makes More Sense?

Both options can give you more time in Thailand. Under the current rules they are closer than they used to be, because air and land entries on the exemption both give 30 days.

When the Extension Wins

You are mid-trip and do not want to leave. The extension costs 1,900 THB and a morning. A border run costs transport, any fees at the other side, possibly accommodation, and at least a full day of travel.
You have already used your land entries. Land entries on the exemption are generally limited to two per calendar year, so a land border run may not be available to you.
It is your first extension. A clean passport and a clear plan to leave give you the best chance of approval.
You do not want to deal with border logistics. No bus schedules, no ferry timetables and no visa for the neighbouring country.

When the Border Run Wins

You want to visit a neighbouring country anyway. If Langkawi, Vientiane or Luang Prabang is on your list, combining the trip with genuine travel makes sense. See our border run guide for the crossings, and remember that land crossings with Cambodia are suspended.
You have already reached the 60-day limit. After an extension you cannot extend the same entry again. If you want to stay in Thailand longer, you need to leave and enter again or get a visa.
Your extension was refused. Leaving before your stamp expires and entering again later is the clean way to continue your trip, if the border officer admits you.

The Math

Option	Cost	Time	Days Gained
Extension at immigration	1,900 THB	Usually a morning	Up to 30 days, at the officer's discretion
Border run by land	Transport and any fees on the other side	Full day minimum	30 days; counts toward the twice-a-year land limit
Fly out and back	Return flight	Full day	30 days, at the border officer's discretion

For most backpackers mid-trip, the extension is the path of least resistance. For travellers who have already reached 60 days, a trip out of Thailand or a Tourist Visa is the next step.

Common Mistakes (And How to Avoid Them)

These are the mistakes that send people away from the counter most often.

Forgetting to sign the photocopies. Sign every copy before you go. An unsigned copy can cost you your place in line.

Wrong date format. Write dates day first: DD/MM/YYYY. Americans especially get tripped up by writing the month first. Check every date field on your TM.7 form twice.

No printed photo. Not a photo on your phone. Not a photocopy of your passport photo page. An actual printed, recent photo.

Showing up late in the day. Some offices stop taking applications well before they close, and many pause for lunch. Arrive early.

Waiting until the last day. If anything goes wrong on your final day, including a refusal, you are overstaying. Apply with days to spare.

Assuming the old 60-day rules. The 60-day exemption and its 90-day maximum ended on 15 September 2026. Count from your stamp, not from an old blog post.

Leaving the address field vague. "Bangkok" or "Koh Phangan" is not an address. Write the full name and address of your accommodation. If you do not know it, look it up before you leave your hostel.
