The Samui Immigration Office is located at Maenam Road 333, Soi 1, Moo 1 in Mae Nam on the north coast and is open Monday to Friday from 8:30 a.m. to 4:30 p.m. (with a lunch break). Telephone: 077 423 440. They process, among other things, tourist permit extensions, 90-day notifications, re-entry permits, address notifications according to TM.30, and long-term stay extensions for the island. Koh Phangan and Koh Tao each have their own immigration offices.

The short answer
For a 30-day tourist visa extension or other matters, please contact the Immigration Office in Mae Nam on Koh Samui. Do not go to Nathon, where the office used to be located. It is closed on weekends and public holidays. On Koh Samui, you can apply for the extension online in advance and only need to be there in person for the stamp. If you are staying on Koh Phangan or Koh Tao, please use the Immigration Office on your respective island.
The rules for each office in Thailand, including the online procedure and rejection policies, can be found in the extension portal.
The island offices of the Surat Thani Immigration Department and which one you should use
Addresses, phone numbers, opening hours, and the responsibilities of the airport branch are taken from the Surat Thani Immigration Bureau website. The website lists opening hours for the province as 8:30 a.m. to 4:30 p.m.; there are no separate opening hours for the branches on the islands. Opening hours for Samui and Phangan, including lunch breaks, are taken from their respective Google listings. According to the immigration office handbooks, applications are submitted to the immigration office in the applicant's place of residence.
The office in Mae Nam
Samui Immigration is a department of the Surat Thani Provincial Immigration Office, headquartered on the mainland near Surat Thani city. According to the provincial website, the building on Maenam Road Soi 1 opened on August 18, 2018, and serves as the central point of contact for all visa matters on the island. The address can be found on the Surat Thani Immigration contact page and in the electronic visa renewal list.
The Google listing shows a free parking space, a paid parking space, and a wheelchair-accessible entrance.
Arrival in Mae Nam
Mae Nam is located on the north coast of Koh Samui, east of Bophut and the fishing village, and west of Nathon. The office is on Soi 1, a side street off the main road. Lomprayah boats from Koh Phangan and Koh Tao dock at Pralarn Pier in Mae Nam. According to directions from a travel agency on Koh Tao, the office is 3.9 km from the pier; you need to turn off the main road at a FamilyMart. From Chaweng, Lamai, or the airport, a Grab or Bolt will take you directly to the entrance. During the day, shared taxis (songthaews) run along the ring road through Mae Nam. Just tell the driver "Soi 1" or get out on the Soi and walk the rest of the way.
Inside and how the queue works
A local guidebook describes the office as a reception area on the ground floor where staff check your documents and give you a waiting number. There are separate queues for tourist matters, short-term stays, and long-term stays. The case workers who process your application are located upstairs. The building also has a photo and copy room, as well as a small coffee corner for those waiting.
According to the immigration office's handbook, processing a tourist visa takes 40 minutes from the moment all documents are complete. The waiting time for the processing number is additional, and visa offices on the island recommend allowing almost a whole morning during peak season.
The Surat Thani Immigration Department publishes announcements on its website (suratthani.imm.police.go.th) and its Facebook page (Suratimmigration). Check both before your trip, especially on long weekends.
Can I book an appointment?
Immigration Division 6, responsible for the south, offers an online booking calendar for its office on Samui, but the link leads to an error message. The calendar for the mainland office in Surat Thani, however, works and offers appointments for tourists. The Surat Thani immigration office website also links to its SIMM HUB app. The app's entry describes booking via the Fast Lane queue, but doesn't specify which offices accept it. I would therefore recommend going in person and taking a number.
The e-extension is most comparable to a booking, where your tourist extension is decided online and you only need to make one visit to collect the stamp.
The 30-day tourist extension on Koh Samui
A visa exemption stamp or a 60-day tourist visa can be extended once for up to 30 days for a fee of 1,900 baht. The decision is at the discretion of the officer. On Koh Samui, this is done at the office in Mae Nam. The 30 days are added to the end of your current stamp, not the date of application. Therefore, you will not incur any additional costs if you arrive a week earlier.
The Immigration Office's handbook for tourist stay extensions, published on the Surat Thani Immigration Department's website, lists your passport and a copy thereof, form TM.7 with photo, a form confirming penalties for overstaying, and the fee. Visa offices on the island also recommend copies of the remaining pages of your passport and proof of accommodation.
1. Document check and queue number
Bring your passport, the completed TM.7 form with the 4x6 cm photo, signed copies of the photo page and entry stamp (as well as your tourist visa or e-visa, if applicable), your hotel booking or your landlord's receipt (TM.30 form), and 1,900 baht in cash to the reception desk. The staff will check your documents and give you a number. The confirmation of overstay mentioned in the handbook is a short form from the immigration authorities that you sign along with your application.
2. At the counter
When your number is called, an official will take your passport and documents, record your details including your photo, collect the fee of 1,900 baht, and give you a receipt. The official may request further proof, such as a ticket for onward travel.
3. The postage stamp
If your application is approved, the new authorization will be stamped in your passport, signed, and given to you. Please read the date before leaving the counter.
Online application with e-renewal
Samui is listed in the VFS Global Immigration Office's online e-Extension system. There, Surat Thani is listed only as Koh Samui and Koh Phangan, and the address in Mae Nam is given as the collection point for the stamp. You submit the application at thaiextension.vfsevisa.com if your stamp is valid for less than 45 days before its expiration date. The fee is 1,900 baht plus a 500 baht processing fee. After one to seven business days of processing, you must travel to Mae Nam once to have the extension stamped. The Surat Thani Immigration Office website links directly to the system.
Complete documentation does not guarantee an extension. The decision rests with the official; the fee of 1,900 baht is non-refundable in case of refusal; each day overstaying the permitted stay costs 500 baht.
What you should bring for the extension
A completed TM.7
Fill it out beforehand or ask at the office for a blank form. My TM.7 guide explains each field using a completed example.
A 4×6 cm photo
It's glued into the photo slot of the TM.7. It's larger than a passport photo, and the office photo booth can take one.
Passport and certified copies
Your passport, as well as signed copies of the photo page and the last entry stamp, and the visa page or e-visa if you have a tourist visa.
1,900 Baht in cash and your address
This also includes the name and address of your hotel or the TM.30 receipt from your landlord.

The 90-Day Report (TM.47)
Anyone permitted to stay in the country for more than 90 days must report their address every 90 days using form TM.47. This report can be submitted 15 days before and up to 7 days after the due date. Late reporting requires a personal appearance and payment of a 2,000 Baht fine (see the Immigration Department's handbook). Tourists exempt from this reporting requirement and granted an extension do not reach the 90-day limit and therefore do not need to report.
On Samui, go to the office in Mae Nam with your passport, the completed form TM.47, and your most recent receipt. According to the manual, the processing time at the counter is four minutes. There are no fees, and someone else can register for you as long as you arrive on time.
Online and by post
The Surat Thani Immigration Bureau website links to the office's online TM.47 system. Expat groups in other parts of Thailand report that the initial declaration after arrival is not being accepted. Therefore, plan to submit the initial declaration in person after each entry. According to the manual, you can send the TM.47 form by registered mail, along with signed copies of your photo page, your most recent entry stamp, and your visa, to 333 Maenam Road, Soi 1, Moo 1, Mae Nam, Koh Samui, Surat Thani 84330, starting 15 days before the due date.
Re-entry permits
A re-entry permit extends your residence permit or long-term residence permit during your departure from and re-entry into Thailand. It costs 1,000 baht for a single re-entry and 3,800 baht for multiple re-entries. The fee is non-refundable if the application is rejected. You will need form TM.8 with a passport photo (4 x 6 cm) and your passport. Apply at the immigration office in your place of residence, in Mae Nam on Koh Samui. I recommend applying for the permit there before your flight, rather than relying on a counter at the airport.
TM.30 and residence permits
TM.30 is the notification that anyone hosting a foreign national must submit to the Immigration Bureau within 24 hours of their arrival. Hotels will handle this for you. For a villa, condominium, or holiday home, the owner is responsible. The notification can be submitted in person at Mae Nam, by registered mail, or online through the Immigration Bureau's TM.30 system, which is linked on the Surat Thani Immigration Bureau website. Ask your landlord for a receipt and keep a copy with your passport documents.
Residents report that the office in Mae Nam also issues the residence certificate, the document that confirms your address for a Thai driver's license or a bank.
Retirement, marriage, education, business and DTV expansions
Long-stay extension applications from Koh Samui residents are processed in Mae Nam. According to a local guide, there is a separate queue for long-stay matters at the reception desk. If your application is approved, you can track its status online through the Surat Thani Immigration Bureau using your passport number and receipt number. Visa requirements can be found in my visa guide. Holders of a DTV visa, whose 180-day stay can be extended once per entry, should call 077 423 440 before traveling.
The offices on Koh Phangan and Koh Tao
Koh Phangan has had its own immigration office since May 20, 2021, located at 13/47 Moo 2, telephone 077 377 947. Therefore, Koh Phangan residents no longer need to travel to Samui to extend their tourist stay. Koh Phangan guidebooks locate the office on the grounds of the police station outside Thong Sala, about 1.5 km inland from the pier. The Google listing indicates the same weekday opening hours as Samui, and e-Extension lists it as a collection point for passport stamps. According to guidebooks, tourist stay extensions and 90-day reports are processed there. Long-term stay extensions have been handled in Samui since 2021, so it is recommended to call ahead for all other matters. Guidebooks also note that a dress code is in place at the office, and those wearing sleeveless tops have been asked to change. A local coworking space also lists the STM.2 confirmation form and the TM.30 receipt as required documents.
Koh Tao has had its own immigration office since July 12, 2021, located on the second floor of the district administration building in Moo 3 (phone: 077 456 947). The Surat Thani immigration office does not publish opening hours or information about its services. However, a travel agency on Koh Tao reports that they process tourist visa extensions and 90-day notifications there. Therefore, it is advisable to call ahead. Koh Tao is not authorized for electronic visa extensions (e-extensions). The VFS (Visitor Service Service) allows tourists to collect their visa stamp at a different office than the one where the application was submitted. Therefore, applying online for Koh Tao means you will need to travel to Koh Phangan or Koh Samui to get the stamp.
Opening hours, public holidays and best time to travel
The office is only open Monday to Friday, from 8:30 am to 4:30 pm. It is closed on weekends and Thai public holidays. I would avoid working the first day back after a long weekend.
A local guide advises arriving early or just before the end of the lunch break, as anyone arriving after 10:00 AM risks having to return after lunch. I would be on Soi 1 before 8:30 AM and never plan to stay until the last working day before a holiday.
Outdated information you should ignore
The office moved from Nathon to its building in Mae Nam on August 18, 2018, although some pages still state the year as 2016. Any pages, map markers, or directories that refer you to Nathon or Ang Thong for an extension are outdated, as is any information regarding a district office address in Mae Nam or a telephone number other than 077 423 440. The Surat Thani Immigration Bureau's contact page currently does not list an office in Nathon.
Pages written before September 15, 2026, describe the extension of a 60-day exception; this is now 30 days. Checklists requesting a copy of the departure card predate the introduction of TDAC processing. Older advice regarding Phangan and Koh Tao to take the ferry to Samui for all visa matters predates the opening of visa offices on those islands in 2021.
