What it is
THIM (Thailand Immigration Management) is the Immigration Bureau's official app. It launched as a pilot in May 2026, with a full rollout planned from 1 October 2026.
What it does
- Now: your TDAC arrival card, including for your family or group.
- Promised next: 90-day reports, extension applications, booking a queue at an immigration office, and document requests.
- Early users reported freezes and errors, so don't rely on it for anything with a deadline yet.
What hasn't changed
TDAC is still required before every arrival, and 90-day reports, extensions and TM30 still work the way they did until the new features are live and reliable.
Never miss your own deadlines
Answer five quick questions and we'll list every date that applies to you: 90-day reports, extensions, re-entry permits and tax. Free to start.
Sources we checked
General information, not legal or tax advice. Immigration offices don't all apply the rules the same way, so check anything important with your local office. Spotted something out of date? Email Joshua.
