1. Overview
The two obligations most often confused in Thailand are the 90-day report and the visa extension. They are different things, they fall due at different times, and completing one does not satisfy the other.
The 90-day report (form TM47) is an address notification. If you stay in Thailand for more than 90 consecutive days, you tell Immigration where you are living — and you repeat it every 90 days for as long as you remain. It does not extend anything; it simply keeps your address on record.
A visa extension (form TM7) is a separate application to lengthen your permission to stay when your current visa or extension is running out. This is the one tied to your visa type and its financial conditions.
A re-entry permit (form TM8) is a third, different thing again: it protects the permission you already hold when you leave Thailand. Without one, departing can void the extension you have already paid for.
These obligations sit on top of whichever visa you hold — retirement, marriage, business, education or otherwise. That is why this page sits alongside the visa pages rather than being a visa category of its own.
2. Who This Applies To
- 90-day reporting (TM47) applies to anyone staying in Thailand beyond 90 consecutive days on a long-term visa or extension — retirement, marriage, business, education and others alike.
- Visa extensions (TM7) apply when your current permission to stay is expiring and you want to remain — used for tourist, non-immigrant, retirement and marriage extensions among others.
- Re-entry permits (TM8) apply to anyone holding a visa or extension who intends to leave Thailand and return on the same permission.
- Leaving and re-entering resets the count of consecutive days, which is what determines when a 90-day report next falls due.
3. 90-Day Address Reporting (TM47)
The recurring obligation that catches people out most often. It is a notification of where you live, not a renewal of anything:
- Who files: the foreign national — every foreigner holding a long-term visa or extension must notify Immigration of their residence every 90 days.
- How to file: in person at local Immigration, by post, or through the online TM47 system where the local office supports it.
- Filing window: generally from 7 days before until 15 days after the due date.
- If you file late: a fine may apply — commonly cited at around THB 2,000.
- It is not an extension: filing your 90-day report has no effect on when your permission to stay expires.
Filing windows, late fines and online-filing availability can vary by office and change over time. Contact OneStop Hua Hin to confirm the current requirements for your reporting date.
4. Visa Extensions (TM7) & Re-Entry Permits (TM8)
Visa Extensions — TM7
- Used to request an extension of your permitted stay — tourist, non-immigrant, retirement, marriage and other categories.
- Fee is around THB 1,900, though this can vary by office.
- Depending on visa type, offices may grant extensions of 7, 30, 60, 90 or 365 days.
- A tourist visa is valid for 60 days and is commonly extendable by a further 30 days.
Re-Entry Permits — TM8
- Needed before you leave Thailand if you hold a visa or extension and intend to return on it.
- Available as single or multiple re-entry, with multiple costing more.
- Without a valid re-entry permit, leaving the country may void your current permit or visa.
- Apply before departure — this cannot be fixed after you have left.
Required documents, processing times and re-entry permit fees vary by office and by visa type. Contact OneStop Hua Hin for a document checklist and current fees before you apply.
5. Where To File in Hua Hin
Hua Hin has two separate Immigration offices, and which one you need depends on what you are filing — going to the wrong one is a common wasted trip.
Main Hua Hin Immigration Office — Monday to Friday, 8:30–12:00 and 13:00–16:30. Located outside the city centre near the airport and the Blue Lagoon area. Handles the matters that need detailed review: visa extensions (short-term and long-stay), re-entry permits, visa conversions, special stay permissions and other complex cases.
Hua Hin Immigration at Blúport Shopping Mall — Monday to Friday, 11:00–17:00. Inside Blúport Hua Hin Resort Mall on Phetkasem Road. Handles the simpler day-to-day services: 90-day reports, residence certificates and selected administrative tasks.
In short: routine 90-day reports at the mall office, extensions and re-entry permits at the main office. Requirements do shift between years and offices, so it is worth confirming before you travel.
Other Forms That Affect Your Status
- TM30 — notification of where a foreigner is staying, filed by the house owner, landlord or manager, normally within 24 hours of arrival or a change of address. Applies to private homes and condos, not just hotels. If it has not been filed correctly, Immigration may refuse a later extension.
- TM28 — change of address, or staying in another province for more than 24 hours. Keeps your address record accurate, which matters when you later file a TM47 or apply for an extension.
- TDAC — the Thailand Digital Arrival Card that replaced the TM6, completed before arrival by every non-Thai entrant. Mandatory since 1 May 2025.
6. Frequently Asked Questions
No, and this is the single most common misunderstanding. The 90-day report only tells Immigration where you are living. Your permission to stay still expires on the date in your passport stamp, and extending it is a separate application on form TM7 with its own paperwork, fee and financial conditions. Keep track of both dates independently.
An online TM47 system exists and is accepted by many provincial offices, alongside filing in person or by post. Availability has not been consistent everywhere, and some offices have periods where online submissions are not accepted or are rejected close to the deadline. We confirm what the Hua Hin office is currently accepting before relying on it.
Late filing generally attracts a fine — commonly cited at around THB 2,000 — and you would normally file as soon as you realise rather than waiting for the next cycle. Amounts and how strictly the window is applied can vary by office and change over time, so treat this as an indication rather than a fixed figure.
