Nonthaburi has its own provincial immigration office - separate from Bangkok's Chaeng Wattana - and knowing that distinction saves long-stay residents a wasted trip. Here is where the Bang Kruai office is, how it differs from Chaeng Wattana, what to bring for 90-day reporting, visa extensions, TM30 and re-entry permits, and how to keep each visit short.
Long-stay foreigners registered in Nonthaburi province deal with their own provincial immigration office, not Bangkok's Government Complex on Chaeng Wattana Road - a distinction that trips up plenty of residents, since Chaeng Wattana sits just across the provincial line and gets mistaken for a Nonthaburi facility. The real Nonthaburi office is a quieter, more low-key building on Nakhon In Road in Bang Kruai, and it handles the same core business: the 90-day address report, the annual extension of stay, TM30 address notification, and the re-entry permit that protects an extension when you travel. This guide covers exactly where to go, how it differs from Chaeng Wattana, the three ways to file a 90-day report, how extensions, TM30 and re-entry permits fit together, the fees, and how to make each visit as painless as possible.
Nonthaburi has its own provincial immigration office, separate from Bangkok's. It sits at 954 Moo 1, Soi Ruam Mit, Nakhon In Road, Bang Khanun Subdistrict, Bang Kruai District, Nonthaburi 11130 - on the west bank of the Chao Phraya, not far from the Nonthaburi side of the Rama V bridge area. This is where anyone whose registered address (the one on your TM30) falls inside Nonthaburi province handles extensions of stay, 90-day reports, re-entry permits and related visa business, rather than travelling into Bangkok.
A lot of confusion comes from geography: Bangkok's main immigration office - the Government Complex on Chaeng Wattana Road - sits in Lak Si District, technically inside Bangkok, but so close to the Nonthaburi provincial border that many Nonthaburi residents (and even some local guides) casually refer to it as "Nonthaburi's" office. It isn't. Which office is yours depends on where your address is registered, not on which is closer or better known - confirm your correct office before you make the trip, since paperwork filed at the wrong office can bounce back.
Counters run the standard government schedule: roughly 8:30am to 4:30pm, Monday to Friday, closed on Thai public holidays. The office was upgraded in recent years and is now more spacious and fully air-conditioned than the older building it replaced, with visa-extension and 90-day-report services handled on the upper floor. It is far quieter than Chaeng Wattana - long-time visitors report walking in, taking a queue ticket and being called within minutes on an ordinary weekday, though it is still sensible to arrive earlier in the morning for anything more involved than a routine 90-day report.
The office sits off the main roads on the Bang Kruai side of Nonthaburi, away from the MRT Purple Line, so it is not a walk-in-from-transit destination. Grab or a metered taxi from anywhere in Nonthaburi or western Bangkok is the practical option; drivers unfamiliar with the soi sometimes need the Thai address or a pinned map location, so have it ready before you set off. Give yourself extra travel time on your first visit - it is a genuine government office tucked into a residential and riverside area, not a shopfront on a main road.
Any foreigner who stays in Thailand for 90 consecutive days or more on a long-stay visa or extension must report their current address to immigration every 90 days. It is a notification of where you live - not a visa renewal - and it does not extend your permission to stay. The clock resets every time you leave and re-enter the country, so residents who travel often rarely trigger it, while those who stay put in Nonthaburi must file on schedule. Keep every receipt slip; it sets the date of your next report.
You can report in person at the Bang Kruai office within the window of 15 days before to 7 days after your due date. Bring your passport, a completed TM47 form and your previous 90-day receipt (or your latest entry stamp if this is your first report). In-person reporting is the most reliable method because you leave with a stamped receipt showing your next due date, and staff can correct any address mismatch on the spot.
Immigration's online 90-day reporting system (website and app) lets you file from home within the same window, once your first report has been made in person at your correct office. It is the easiest option when it works, but the system can be fussy about matching your details, so file early in your window rather than on the last day and save your confirmation reference. If it repeatedly fails, fall back to mail or an in-person visit before your deadline passes.
You can also report by registered post: send a completed TM47 form, a signed copy of your passport photo page, visa page, latest entry stamp and departure card, your previous receipt, and a stamped self-addressed envelope, timed to arrive within the reporting window. The Nonthaburi office mails back a fresh receipt with your next due date. Use trackable registered mail and keep your posting receipt in case the reply is delayed.
Missing a 90-day report is a common, fixable slip: the standard fine is 2,000 baht, paid in person when you next report. If you are caught with an overdue report at an airport or checkpoint the penalty is higher (around 5,000 baht), and repeated lapses draw more scrutiny at extension time. If you realise you have missed it, go in person as soon as you can and pay the fine rather than letting it slide.
Long-stay foreigners registered in Nonthaburi renew their permission to stay - retirement, marriage, education, employment (Non-B) or as a dependant - at this office rather than at Chaeng Wattana. The government fee is 1,900 baht, and each category has its own document set: retirement and marriage extensions typically need bank letters and seasoned funds or income evidence, a TM7 application, photos and copies of every passport page. Confirm current appointment-booking requirements before you go, since immigration offices nationwide have been moving extensions towards booked slots.
The TM30 is a report of where a foreigner is staying, and by law the property owner or "possessor" - your landlord, condo juristic office, or a hotel - must file it, usually within 24 hours of your arrival at the address. You typically need an up-to-date TM30 on file before you can complete a 90-day report or an extension at the Nonthaburi office, so confirm your landlord or building has filed it (many do so online) and get a copy of the acknowledgement. If you own or fully control your residence, you can file it yourself.
If you hold an extension of stay and leave Thailand without a re-entry permit, your extension is automatically cancelled and you return as a fresh visitor, losing the long-stay status you built. Before any international trip, buy a re-entry permit at the Nonthaburi office in advance - a single re-entry costs 1,000 baht and a multiple re-entry 3,800 baht - or at the immigration counter in the airport before departure, though the airport counter means arriving with extra time to spare.
Core fees are modest: 90-day reporting is free, an extension of stay is 1,900 baht, and re-entry permits are 1,000 or 3,800 baht. Some expats use a visa agent to handle paperwork and queueing - convenient, but at added cost, and you still generally appear in person for extensions. To keep a visit smooth: bring your passport plus signed photocopies of every relevant page, confirm the current document checklist for your visa category in advance, make sure your TM30 is current, and build in extra travel time given the office's location off the main roads.
The Nonthaburi Provincial Immigration Office is at 954 Moo 1, Soi Ruam Mit, Nakhon In Road, Bang Khanun Subdistrict, Bang Kruai District, Nonthaburi 11130, on the west bank of the Chao Phraya. It handles extensions of stay, 90-day reporting, TM30 matters and re-entry permits for anyone whose registered address falls inside Nonthaburi province. It is open roughly 8:30am to 4:30pm, Monday to Friday, closed on Thai public holidays.
No. Chaeng Wattana - the large Government Complex immigration office many expats know from Bangkok - sits in Lak Si District, Bangkok, not Nonthaburi, even though it is close to the provincial border. Which office you use depends on where your address is registered (your TM30 address), not which one is closer or more famous. Residents registered in Nonthaburi should use the Bang Kruai provincial office rather than Chaeng Wattana.
You can report your address every 90 days at the Nonthaburi office in person (bring your passport, a completed TM47 and your previous receipt), online through the immigration website or app once you've made an initial in-person report, or by registered mail with your forms and signed passport copies. All three must be done within the window of 15 days before to 7 days after your due date. In-person reporting is the most reliable, since you leave with a stamped receipt showing your next date.
No - the 90-day clock resets every time you leave and re-enter the country. The report is only required after 90 consecutive days of staying in Thailand, so travellers who go abroad and return have their next report due 90 days from their latest entry. It mainly affects long-stay residents who stay put in Nonthaburi for extended stretches.
Yes, if you hold an extension of stay and plan to leave and return. Leaving without a re-entry permit automatically cancels your extension, and you come back as a fresh visitor. Buy a re-entry permit before you fly - 1,000 baht for a single re-entry or 3,800 baht for multiple - either in advance at the Nonthaburi office or at the immigration counter in the airport before departure.
