Thailand’s THIM immigration app is live, but its role is still narrower than many early headlines suggested. In October 2026, foreign travellers can use THIM as a mobile route for arrival registration linked to the Thailand Digital Arrival Card (TDAC). Visa extensions and 90-day reporting are future functions announced for the wider platform, not services this article treats as already available to everyone.
What THIM is today
THIM — the Thailand Immigration Management application — is an official Immigration Bureau platform for foreign nationals. The Tourism Authority of Thailand and Thailand’s Government Public Relations Department describe it as a digital registration and immigration-services project.
The app is an optional channel for arrival registration. Travellers should still follow the current TDAC requirement and use the official Immigration Bureau channel. THIM does not create a second arrival-card obligation, and users should not submit duplicate information simply because both the app and web form exist.
Features currently available or documented
- TDAC-linked arrival registration: enter accommodation, travel and purpose-of-entry information.
- Passport scanning: the app can read passport details from a photograph.
- Group registration: official launch information says one session can cover up to 10 travellers.
- Mobile access: THIM has been made available through major mobile-app stores, subject to current version and device availability.
- Initial language support: official launch material identified English, Russian, Japanese and Chinese, with more languages planned.
Visa extensions and 90-day reporting: planned, not assumed live
Thai government and Immigration Bureau announcements describe THIM as a platform that may later support digital document submission, appointment arrangements, status tracking and selected applications that do not require a physical visit. The Immigration Bureau has also said that future expansion may include visa-extension requests and 90-day residence notification.
Those statements describe the platform’s development roadmap. They do not mean that every category of visa extension or every 90-day notification can now be completed inside THIM without visiting Immigration. Until the app shows a service for the relevant category and the Immigration Bureau confirms the operating rules, use the established official process and keep your deadline.

What travellers should do
- Download only the official THIM application and check the publisher before entering passport data.
- Complete the required TDAC information through the official route available to you before arrival.
- Keep the confirmation and passport details available for inspection.
- For extensions, re-entry permits or 90-day reporting, follow current Immigration Bureau instructions for your visa category unless THIM clearly confirms the service and eligibility.

THIM status: live, limited or planned?
Checked 30 October 2026. The official launch material described a trial app and an August target for broader implementation, but a target date is not proof that every advertised service is available to every user.
| Function | Status to rely on |
|---|---|
| Passport scan and TDAC-linked arrival details | Documented in the official trial |
| English, Russian, Japanese and Chinese | Documented initial languages |
| Group registration for up to 10 travellers | Documented in launch information |
| Appointments, document requests and status tracking | Use only when shown as active in your account |
| Visa extensions and 90-day reporting | Do not assume universal availability; keep the established deadline and process |
Troubleshooting without missing a deadline
- Use only the official app or THIM web domain; verify the publisher before uploading passport data.
- If scanning fails, enter the passport fields exactly as printed and try a clear, glare-free image.
- Do not submit duplicate TDAC records through both channels.
- If a service is absent, errors persist or the deadline is close, use the established Immigration Bureau process instead.
