90-day reporting: online, by post or at the office

Steps

"Tip" marks a planning suggestion, not an official rule.

1. Tip Check your previous reporting receipt and latest entry date, and manage the reporting schedule separately from your stay expiry.
2. The older guidance displaying 2022 describes online submission from 15 days before the due date. Confirm the current opening date and deadline with the office before applying.
3. Do not stop at a pending status after submission. Check the result and your next reporting due date.
4. Tip If approval cannot be confirmed or the form rejects your entries, contact your local office before the deadline and check another route, such as in-person submission.

What to prepare

• The older postal guidance lists TM47, copies of relevant passport pages, the previous receipt and a return envelope. Confirm the current document list with your local office.

Where to ask

Things to watch for

Separate the report date from your stay expiry

The Immigration reference is dated 18 April 2022. The deadlines and conditions below may differ from current Chiang Mai requirements. Check your office’s latest instructions before choosing a filing method.

Immigration distinguishes 90-day reporting from an extension of stay: reporting does not extend your permitted stay. It also explains that the count restarts from the latest re-entry after leaving Thailand.

LTR has an annual-reporting provision. Do not apply the same 90-day schedule to every long-term resident.

Check the online result

The older guidance describes checking the result after submission. It also says that after a passport renewal, a report at the local office, personally or through a representative, comes first. These conditions have not been confirmed as current; contact your office before applying with a renewed passport.

Do not transfer deadlines between submission routes

The older guidance gives a general window from 15 days before to seven days after the due date, and registered-post dispatch at least 15 days before it. Current in-person, postal and online deadlines have not been verified. Confirm your own deadline with the office rather than applying one route’s window to another.

Chiang Mai’s current postal address, return-postage amount and treatment of TM6 remain unverified. Ask the office about these points before choosing post.
