Once you settle into the EEC's corporate core, the Sriracha Immigration Office becomes a regular fixture: it's where you file your 90-day report, renew your Non-B or retirement extension of stay, sort a re-entry permit before a business trip, and pick up the certificate of residence you need for a driving licence or a car. Here's the 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 Chonburi's EEC belt — Sriracha, Laem Chabang, Amata Nakorn or Chonburi City — on a Non-B work visa, retirement, marriage, DTV or LTR permission, immigration is not a one-off formality but a recurring part of provincial life. The Sriracha Immigration Office handles the 90-day address report every long-stay resident owes, the renewable one-year extension of stay that keeps you here (most often tied to a work permit in this corporate province), the TM30 address notification your landlord or employer must file, the re-entry permit that protects your extension when you travel for business, 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 it is and who it covers, how each errand works and what to bring, the four ways to file your 90-day report, and how to stay well clear of overstay. Pair this with the Chonburi visa run & border run guide and the Thailand visa guides for the rest of a relocation plan.
Because Chonburi's rental market runs on employer-sponsored relocation rather than tourism, the single busiest counter at Sriracha Immigration is the Non-Immigrant B extension tied to a work permit — the paperwork that keeps a manager, engineer or technician legally in the country for a Sriracha, Laem Chabang or Amata Nakorn assignment. HR teams and relocation partners usually prepare the packet, but the employee still needs to show up in person with their passport, and knowing what the office expects speeds up what is otherwise a routine annual errand.
Anyone in Thailand on a long-stay extension — Non-B work, retirement, marriage, DTV, LTR, education or family — must report their current address to immigration every 90 days. Sriracha Immigration handles this for residents registered anywhere in its coverage area, 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 or your company's relocation partner. Missing the deadline carries a fine, so most long-stayers diarise the due date printed on the receipt slip.
Under Thai law the 'house master' — your landlord, condo owner, hotel or, for company-arranged housing, sometimes the employer acting on the landlord's behalf — must notify immigration that a foreigner is staying at their address, normally within 24 hours of moving in or returning from abroad. The resulting TM30 receipt is one of the most important documents you hold in Chonburi: Sriracha Immigration usually wants to see it before processing a 90-day report, an extension or a certificate of residence. Confirm your landlord or building juristic office has filed it — a missing TM30 is the 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. Frequent business travel is normal for EEC-based engineers and managers, so this is worth sorting well ahead rather than at the airport counter. You can get one at Sriracha Immigration in advance, or at Suvarnabhumi or U-Tapao before departure, but doing it at the calm provincial office beforehand is far less stressful than a departure-day queue. Skip it and even a short work trip abroad forfeits your extension.
The Sriracha Immigration Office covers Chonburi province outside of Banglamung, Koh Sichang, Sattahip and Pattaya districts — meaning it is the correct office for Sriracha, Laem Chabang, Amata Nakorn and Chonburi City directly, the districts that make up the province's corporate and industrial core. Pattaya-area residents use the separate Jomtien Immigration Office instead. Sriracha Immigration is open Monday to Friday, 8:30am–12pm and 1–4:30pm, and closed on weekends and public holidays; confirm the current address and any satellite service points before you travel, since details can change.
Sriracha Immigration runs on a queue-ticket system and is busiest first thing in the morning, around the end of the month when extensions cluster, and after long weekends. Arrive early, dress for a government office (shorts or beachwear can get you turned away), and bring something to read — even a simple 90-day report can mean a wait. Extensions in particular can involve a second visit, so employees and HR teams should never leave the errand until the final days before permission to stay expires.
Whatever the errand, bring your passport, your TM30 receipt, and photocopies of your passport photo page, visa/extension stamp and departure card — signed. Non-B extensions add the work-permit book, an employer letter and supporting company documents; retirement and marriage extensions add financial evidence, photos and the relevant application form; certificates of residence add proof of address such as a lease or company housing letter. Requirements differ by errand and change over time, so confirm Sriracha's current checklist first — losing your queue place to find a photocopier is a classic avoidable mistake.
Chonburi's EEC employers commonly route Non-B extensions and 90-day reporting through an HR-appointed visa agent or relocation partner, who prepares paperwork, handles the TM30 and books appointments — useful given how many relocating staff have limited Thai and tight schedules. A standard 90-day report or straightforward extension does not require an agent and costs nothing beyond the government fee if done yourself, but for company-sponsored moves, letting HR's established process handle it avoids document surprises.
File your 90-day report in four ways: in person at Sriracha Immigration (queue ticket, passport, 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 or relocation partner. The report is due every 90 days 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.
Sriracha Immigration issues a certificate of residence — an official letter confirming your Chonburi address — which you need for a Thai driving licence, buying a car or motorbike, or opening some bank accounts. There is usually a small fee, and processing can take anywhere from same-day to a few days depending on workload, so request it a little ahead of when you need it. This is a common early errand for newly arrived EEC staff setting up daily life in Sriracha or near Amata Nakorn.
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 for anyone on an employer-sponsored visa, since it can also complicate the company's own compliance record. Watch the permitted-to-stay stamp in your passport rather than the visa validity date, and start any extension well before it expires, since Sriracha Immigration can require a second visit. If you travel for business, buy a re-entry permit first.
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. Keep your 90-day due date and extension deadline diarised, or ask HR to track it as part of your work-permit compliance calendar. If the process feels opaque, your company's relocation partner or a reputable local visa agent removes most of the friction. Above all, confirm Sriracha's current requirements, hours and location by phone or online before travelling across the province.
Chonburi's industrial and corporate core — Sriracha, Laem Chabang, Amata Nakorn and Chonburi City — is served by the Sriracha Immigration Office, open Monday to Friday, 8:30am–12pm and 1–4:30pm, closed weekends. Pattaya-area residents use the separate Jomtien Immigration Office instead, since Banglamung, Koh Sichang and Sattahip districts fall outside Sriracha's coverage area. Confirm the current address and hours before you travel, as details can change.
If you live in Thailand on a long-stay extension — including a Non-B work visa — you must report your address to immigration every 90 days. In Chonburi you can do this in person at Sriracha Immigration, by registered post 7–15 days before the due date, online via the immigration website or app, or through an agent or relocation partner. It is separate from your visa and does not extend your stay — it just confirms where you live. Keep the receipt slip, as the next due date is printed on it, and note that leaving and re-entering Thailand resets the 90-day clock.
The TM30 is the address notification that your 'house master' — landlord, condo owner, hotel or sometimes an employer acting on the landlord's behalf — must file with immigration when a foreigner stays at their address, normally within 24 hours of moving in or returning from abroad. Sriracha Immigration usually wants to see the TM30 receipt before processing a 90-day report, an extension or a certificate of residence. Confirm it has been filed and keep a copy — a missing TM30 is the most common reason an immigration errand is bounced.
Yes. The renewable one-year extension of stay tied to a Non-Immigrant B visa and work permit — the most common visa route for Chonburi's EEC workforce — is processed at Sriracha Immigration for anyone whose registered address falls in its coverage area. Employers or relocation partners typically prepare the work-permit book, employer letter and supporting company documents alongside your passport, photos and application form. Requirements vary and are periodically tightened, so confirm the current checklist and start well before your permission to stay expires.
Yes, if you're on a one-year extension of stay. Leaving Thailand for even a short business trip cancels that extension unless you first buy a re-entry permit, single-use or multiple-entry. You can get one in advance at Sriracha Immigration, or at Suvarnabhumi or U-Tapao before departure, but sorting it at the calm provincial office beforehand is far less stressful than an airport queue on travel day. Without one, even a quick trip abroad forfeits your extension and forces you to start the process over.
