Once you settle in the province, Sukhothai Provincial Immigration at Ban Kluai becomes a regular fixture: it is where you file your 90-day report, renew your annual extension of stay, sort a re-entry permit before you travel, and pick up the certificate of residence you need for a driving licence or a car. Here is the expat guide - what the office handles, where it is, how each errand works, and how to keep the whole thing low-stress.
For anyone living in Sukhothai on a long-stay visa - retirement, marriage, the DTV, the LTR, or family - immigration is not a one-off tourist formality but a recurring part of life near this UNESCO-listed historic province. Sukhothai Provincial Immigration handles the 90-day address report every long-stay resident owes, the renewable one-year extension of stay that keeps you here, the TM30 address notification your landlord must file, the re-entry permit that protects your extension when you travel, and the certificate of residence that unlocks a driving licence, a car purchase or a bank account. This guide covers what the office does, where to find it in Ban Kluai, how each errand works and what to bring, the four ways to file your 90-day report, why the TM30 matters so much, and how to stay well clear of overstay.

If you stay in Thailand on a long-stay extension (retirement, marriage, DTV, LTR, education or work), you must report your current address to immigration every 90 days. Sukhothai Provincial Immigration is where residents of the province file this, and it is separate from your visa extension - it does not extend your stay, it simply confirms where you live. You can report in person, by registered post, online through the immigration website or app, or through an agent. Filing more than 7 days after the due date carries a 2,000 baht fine, so most residents diarise the date printed on the slip you receive each time.
The one-year 'extension of stay' - the renewable permission that turns a retirement, marriage, work or family visa into a real long stay - is processed at Sukhothai Provincial Immigration for anyone whose registered address is in the province. You bring the financial evidence (the seasoned bank balance or income for retirement/marriage, or the work permit and company letter for a work-based extension), your TM30 receipt, passport, photos and the completed TM7 form. Requirements and the exact document list vary by office and are periodically tightened, so confirm the current checklist before your appointment and arrive with more copies than you think you need.
Under Thai law the 'house master' - your landlord, condo or serviced-apartment owner, or hotel - must notify immigration that a foreigner is staying at their address, normally within 24 hours of you moving in or returning from abroad. The resulting TM30 receipt is quietly one of the most important documents you own in Sukhothai: immigration usually wants to see it before processing a 90-day report, an extension or a certificate of residence. Make sure your landlord or building manager files it, and keep a copy - a missing TM30 is the single most common reason an immigration errand gets bounced.
A long-stay extension is cancelled the moment you leave Thailand unless you first buy a re-entry permit - single-use or multiple-entry. You can get one at Sukhothai Immigration in advance, or at the airport before departure, but sorting it at the calm provincial office beforehand is far less stressful than an airport queue. Anyone on a retirement, marriage or other one-year extension who travels needs this, or they forfeit the extension and have to start the process again.
Sukhothai Provincial Immigration is located at 109 Moo 10, Ban Kluai Sub-district, Mueang Sukhothai District, Sukhothai 64000. It's reachable by car, motorbike, songthaew or Grab from anywhere in the city area, including the historic park side of town. Confirm the current address, phone line and opening hours before you travel, since government-office details are periodically updated.
Standard hours for Thai immigration offices are Monday to Friday, roughly 8:30am-4:30pm (with a lunch break around midday at many offices), closed on weekends and public holidays. Arrive early, dress neatly (immigration is a government office and shorts or beachwear can be turned away), and bring a book - even a simple 90-day report can mean a wait. Extensions in particular can involve returning for a second visit or a 30-day 'under consideration' stamp, so never leave your errand until the final days before your permission to stay expires.
Whatever your errand, bring your passport, your TM30 receipt, and photocopies of your passport photo page, visa/extension stamp and departure card - signed. Extensions add financial or employment evidence, photos and the relevant application form; certificates of residence add proof of address such as a lease. Requirements differ by errand and change over time, so check the office's current list first. Copy everything before you arrive - losing your queue place to hunt for a photocopy shop is a classic avoidable mistake.
Sukhothai has fewer dedicated visa agents than Bangkok, Chiang Mai or Phuket, but reputable ones operate in and around the city and will prepare paperwork, handle the TM30, book appointments and even queue for you - useful if your Thai is limited or your case is complex. A standard 90-day report or straightforward extension does not require an agent, and doing it yourself is free beyond the government fee, but many long-stay residents use one for annual extensions to avoid document surprises.
You can file your 90-day report in four ways: in person at Sukhothai Immigration (take a queue ticket, hand over your passport and TM47 form, collect the receipt slip), by registered post sent 7-15 days before the due date, online via the immigration website or mobile app (available in a window around the due date, though the system can be temperamental), or through an agent. Filing later than 7 days after the due date carries a 2,000 baht fine. The report is due every 90 days that you remain in Thailand; leaving and re-entering the country resets the clock. Keep the receipt slip - the next due date is printed on it.
Sukhothai Immigration issues a certificate of residence - an official letter confirming your address in the province - which you need to get a Thai driving licence, buy a car or motorbike, or open some bank accounts. There is usually a small fee and it can take anywhere from same-day to a few days depending on the office's workload, so request it a little ahead of when you need it. Some residents instead obtain a yellow house book and pink ID card, which serve as a reusable proof of address and save repeated trips to the immigration office.
Overstaying your permitted-to-stay date is fined 500 baht per day up to a 20,000 baht cap, and a longer overstay can trigger a re-entry ban - a serious risk that is entirely avoidable. Watch the permitted-to-stay stamp in your passport rather than the visa validity date, and start any extension well before it expires, since the office can require a second visit. If you travel, buy a re-entry permit first. Treat immigration dates as hard deadlines and the whole system stays low-stress.
Make sure your TM30 is filed before you go, bring every document plus photocopies, arrive early with a queue ticket, and dress for a government office. Have your 90-day due date and extension deadline diarised so nothing sneaks up on you. If the process feels opaque, a Thai-speaking friend or a reputable local agent removes most of the friction. Above all, confirm the office's current requirements, address and hours before travelling - Sukhothai Immigration's own site lists 055-610112 / 0628281829 as contact numbers alongside the national call centre on 1178.

If you live in Thailand on a long-stay extension, you must report your address to immigration every 90 days. In Sukhothai you can do this in person at the Ban Kluai office, by registered post 7-15 days before the due date, online via the immigration website or app, or through an agent.

Keep the receipt slip you are given, as the next due date is printed on it.
The TM30 is the address notification that your 'house master' - landlord, condo or serviced-apartment owner, or hotel - must file with immigration when a foreigner stays at their address, normally within 24 hours of moving in or returning from abroad. The TM30 receipt is one of the most important documents you hold: immigration usually wants to see it before processing a 90-day report, an extension or a certificate of residence.
Yes. The renewable one-year extension of stay for retirement, marriage, work or family is processed at Sukhothai Provincial Immigration for anyone whose registered address is in the province. You bring the relevant financial or employment evidence, your TM30 receipt, passport, photos and the application form.
