Settling into Khon Kaen — whether as a retiree, a KKU-linked academic, a Srinagarind medical professional or a long-stay family — means a recurring relationship with Provincial Immigration: the 90-day address report, your annual extension of stay, the TM30 your landlord files, and the re-entry permit you need before any trip abroad. The office moved out to Mittraphap Frontage Road, so here's exactly where to go, when, what to bring, and how to handle each errand with the least hassle.
Khon Kaen Provincial Immigration now operates from a purpose-built office on Mittraphap Frontage Road, about 20km outside the city centre, after moving from its former counter at Bus Terminal 3. For anyone living in the province long-term it is a recurring fixture: the 90-day address report every long-stay resident owes, the annual extension of stay that keeps retirees, KKU academics, Srinagarind medical staff and families here, the TM30 address notification your landlord must file, and the re-entry permit that protects your extension when you travel — Khon Kaen has no international land border of its own, so most residents fly when leaving Thailand. This guide covers the current office location, hours and contact details, what each service involves, and how to keep a visit short. Pair it with the Khon Kaen visa & long-stay housing guide and the Thailand visa guides for the rest of a relocation plan.
Khon Kaen Provincial Immigration is located at 197 Mittraphap Frontage Road, Tambon Nonton, Amphoe Mueang, Khon Kaen 40000 — a purpose-built provincial office roughly 20km outside the city centre, on the frontage road toward Udon Thani. It replaced the old counter at Bus Terminal 3 (Baw Kor Sor 3), so if an older guide, agent or map still points you to the terminal, that address is out of date. Because it sits outside the city, most residents drive, arrange a car or hire a Grab/taxi for the trip rather than relying on the songthaews and tuk-tuks that cover the city centre and the KKU/Srinagarind corridor.
The office is open Monday to Friday, 8:30am to 4:30pm, and closed on weekends and Thai public holidays. As with any provincial immigration office, popular errands — extensions of stay and 90-day reporting in particular — get busiest first thing in the morning and toward the end of the month, so arriving early gives you the best chance of finishing your errand in a single visit.
For extension-of-stay enquiries, call 043-306642; for investigation and suppression matters (overstay cases, reporting violations), the separate line is 043-306643. The office's fax number is 043-306642 and general enquiries can be emailed to Khonkaenimm4@gmail.com. Phone numbers and email addresses for provincial offices do change occasionally, so if a call doesn't connect, check the current contact details on the official Immigration Bureau website before making the trip.
Khon Kaen Provincial Immigration handles the whole province, so residents from the city centre, Bueng Kaen Nakhon, the KKU/Srinagarind university and hospital corridor, Central Plaza/Fairy Plaza and the outlying districts all use this single office. Your paperwork is processed by the office responsible for your registered address (the one your TM30 reports), so foreigners living in a neighbouring province — such as Udon Thani or Nakhon Ratchasima — report to that province's own immigration office instead.
Anyone in Thailand on a long-stay visa or extension — retirement, marriage, DTV, LTR, education or work — must report their current address to immigration every 90 days. It is a notification of where you live, separate from your visa, and does not extend your permission to stay; the clock resets every time you leave and re-enter the country. You can report in person at the Mittraphap Road office, by registered post, online through the immigration website or app, or through an agent, and you'll be given a receipt slip each time with your next due date printed on it.
Khon Kaen's foreign community skews academic and medical thanks to Khon Kaen University (KKU) and Srinagarind Hospital, alongside retirees and long-stayers, so the office regularly processes retirement (O-A/O-X), marriage, education (Non-ED, often tied to KKU postings) and employment (Non-B) extensions of stay. Extension applications are generally submitted in the weeks ahead of your current permission expiring — the office can advise the exact window for your visa category — and you'll need the relevant financial or employment evidence, your TM30 receipt, passport, photos and the TM7 application form. Requirements are periodically updated, so confirm the current checklist before your appointment.
The office also handles standard extensions for tourists needing extra time in the province, plus other visa categories that don't fall under the long-stay extension routes. As with all extensions, apply before your current permitted-to-stay date expires rather than on the day itself, since the office may need to process paperwork over more than one visit.
Thai law requires the 'house master' — your landlord, condo owner or hotel — to notify immigration that a foreigner is staying at their address, usually within 24 hours of you moving in or returning from abroad. The resulting TM30 receipt matters more than most newcomers expect: Khon Kaen Immigration typically wants to see it before processing a 90-day report, an extension of stay, or a certificate of residence. Confirm your landlord has filed it (many do so online) and keep a copy, since a missing TM30 is one of the most common reasons an immigration errand gets sent back.
If you hold an extension of stay and leave Thailand without a re-entry permit, that extension is automatically cancelled and you return as a fresh visitor. Buy a single or multiple re-entry permit at the Mittraphap Road office before any international trip, or at the airport counter before departure. Khon Kaen has no international land border of its own — the nearest crossing into Laos is via Nong Khai, a little over two hours away through Udon Thani — so most Khon Kaen residents travelling abroad fly, which makes sorting the permit at the calm provincial office in advance far easier than doing it at the airport on travel day.
Khon Kaen Immigration issues a certificate of residence confirming your provincial address, which you'll need for a Thai driving licence, buying a car or motorbike, or opening some bank accounts (see the Khon Kaen banking guide). There's a small fee and processing can take from same-day to a few days depending on workload, so request it a little ahead of when you actually need it.
Bring your passport, your TM30 receipt, and signed photocopies of your passport photo page, visa/extension stamp and departure card for every errand; extensions add financial or employment evidence, photos and the application form. Arrive early — the office is 20km out of town, so factor in travel time as well as queueing — dress neatly, and confirm your paperwork is complete before you go, since a second trip out to Mittraphap Road for a missing document costs an entire morning. A reputable local visa agent, common in a university city like Khon Kaen, can prepare paperwork and queue on your behalf if your Thai is limited or your case is complex.
Overstaying carries a fine of 500 baht per day up to a 20,000 baht cap, and a longer overstay can trigger a re-entry ban. Track the permitted-to-stay stamp in your passport rather than your visa's original validity date, start extensions well ahead of the deadline, and always buy a re-entry permit before travelling abroad. Treat immigration dates as fixed deadlines and Khon Kaen's admin stays a predictable errand rather than a source of stress.
Khon Kaen Provincial Immigration is at 197 Mittraphap Frontage Road, Tambon Nonton, Amphoe Mueang, Khon Kaen 40000 — about 20km outside the city centre on the road toward Udon Thani. It replaced the older office at Bus Terminal 3 (Baw Kor Sor 3), so double-check you're not being directed to the old terminal location. It's open Monday to Friday, 8:30am to 4:30pm, and closed on weekends and Thai public holidays.
You can report in person at the Mittraphap Road office (bring your passport, TM47 form and previous receipt), by registered post, online via the immigration website or app, or through an agent. The report simply confirms your current address and doesn't extend your visa; the 90-day clock resets whenever you leave and re-enter Thailand. Keep the receipt slip you're given each time, as your next due date is printed on it.
The TM30 is the address notification your landlord, condo owner or hotel — the 'house master' — must file with immigration, usually within 24 hours of you arriving at the address. Khon Kaen Immigration typically wants a current TM30 on file before it will process a 90-day report, an extension of stay or a certificate of residence, so confirm your landlord has filed it and keep a copy of the receipt.
Yes. The office regularly processes retirement (O-A/O-X), marriage, education (many tied to Khon Kaen University postings) and employment (Non-B) extensions of stay for residents registered in the province. You'll need your financial or employment evidence, TM30 receipt, passport, photos and the TM7 form — confirm the current document checklist before your appointment, since requirements are periodically updated, and apply well ahead of your expiry date.
Yes, if you hold an extension of stay. Leaving without one automatically cancels the extension. Khon Kaen has no international land border of its own — the nearest crossing into Laos is via Nong Khai, over two hours away through Udon Thani — so most residents fly when travelling abroad, and it's easiest to buy the re-entry permit at the Mittraphap Road office in advance rather than at the airport on the day.
