Extensions, re-entry permits and 90-day reports all run through one of a handful of immigration offices — and which one is “yours” is decided by where you live. This is the plain-English map: Chaeng Wattana in Bangkok, Jomtien for Pattaya, Phuket and Chiang Mai, what each one handles, how the online queue and appointment systems work, and how to avoid a wasted half-day. Unbiased, never paid placement.
Your immigration office is set by where you live — the province and, in Bangkok, the area on your TM30. Bangkok mostly uses Chaeng Wattana (Division 1), Pattaya uses Jomtien, and Phuket and Chiang Mai have their own offices. Wherever you are: book the online queue where it exists, bring signed copies plus baht cash, keep your TM30 current, and arrive early. Some things — the 90-day report and TM30 — can often be done online instead.
Thailand routes foreigners to the immigration office that covers their registered address, not the nearest one or the one they like. That single rule connects three things newcomers treat as separate: your home, your TM30 address notification, and the office that processes your extensions and reports. Choose a home in one province and your reporting, extensions and re-entry permits all run through that province’s office; move, and they move with you. It’s also why a stale TM30 surfaces at the immigration counter — the office expects a current address notification matching the file in front of them. Get the address right and the right office is automatic. This guide is general information only; jurisdictions, services and procedures change and differ by office, so confirm with Thai Immigration directly.
If you live in much of Bangkok, your office is Chaeng Wattana — the immigration service centre inside the Government Complex on Chaeng Wattana Road in the north of the city, home to Immigration Division 1. It is the country’s largest and busiest, handling visa extensions, re-entry permits, 90-day reports and residence matters for Bangkok residents.
Treat a planned extension here as an appointment-first task: book the online queue, print your confirmation, and still arrive early.
Pattaya doesn’t use Bangkok. Foreigners living in Pattaya and the wider Chonburi province use the Jomtien immigration office, one of the busiest in the country thanks to the area’s large retiree and long-stay population.
The two other offices foreigners mention most are Phuket and Chiang Mai, each serving large expat and long-stay communities.
Every other province has its own provincial immigration office too — the same logic applies: your address sets your office.
The single biggest time-saver is booking ahead where you can. Larger offices run online appointment / queue-booking systems for visa extensions and some services: you reserve a date and time slot and arrive with a confirmation, skipping (most of) the walk-in crush.
Most wasted trips come down to one missing paper. The usual core set, adjusted for your visa and service:
Requirements differ by office and visa type, so check your office’s current checklist first. Our extension guide and re-entry permit guide walk through the specific documents.
Not every task needs a trip. Thailand keeps expanding online and app-based services, and two of the most frequent jobs are often doable from home:
Use online where it works to save journeys, but don’t assume your whole case can be done remotely — confirm with your office.
Sequence it sensibly. Your TM30 should be filed when you move in — ideally by your building — which fixes your office. The 90-day report only matters once you’ve been here three unbroken months, and the re-entry permit the first time you travel out. Our first 30 days checklist places immigration admin in week one alongside your SIM, bank account and neighbourhood search, and our visa-housing guides map each visa route to the kind of home that suits it.
Your address sets your immigration office and your TM30 — so the neighbourhood you choose shapes the admin you’ll carry. Browse residences and areas built for long-stay foreigners.

Thailand’s immigration offices, jurisdictions, online booking systems, services and document requirements change and differ by office; confirm current procedures with Thai Immigration or a qualified local adviser before relying on any of the above.
