Thailand’s Immigration Bureau has spent 2026 tightening entry rules. That includes the visa exemption cut and the DTV changes we’ve covered separately. The newest move is different. Rather than restricting who can come, it’s a technology rollout meant to speed things up. The bureau is currently piloting Thailand’s new THIM (Thailand Immigration Management) app — sometimes described simply as a Thailand immigration app or a Thailand Digital Arrival Card app, since its core job is filling out the TDAC. A full launch is planned for August 2026. This piece explains what THIM does, and what’s confirmed versus still in flux. It also covers what nomads flying into Thailand should do right now. It reflects reporting current as of this writing, in late July 2026.
What THIM Is, According to the Immigration Bureau
The Immigration Bureau announced the project on June 6, 2026. Nation Thailand’s report quotes two Immigration Bureau officials directly: commissioner Pol Lt Gen Panumas Boonyalug and deputy commissioner Pol Maj Gen Pratchaya Prasansuk. According to that reporting, THIM lets foreign nationals photograph their passport’s data page. Users then submit travel and accommodation details before flying to Thailand. The app generates a Thailand Digital Arrival Card (TDAC), the entry document that’s been mandatory since May 2025. Officials describe this as taking under three minutes per person, versus the slower browser-based process currently in use.
THIM didn’t appear out of nowhere. It’s the latest step in a digital-transition push Thai authorities have been running since the TDAC itself became mandatory in May 2025, replacing the older paper arrival card. That transition has since extended into other parts of the entry process, from health declarations to accommodation reporting. Seen in that context, THIM isn’t a new requirement layered on top of the TDAC. It’s an attempt to make an already-mandatory step faster to complete on a phone, using the same underlying data the government already collects.
A separate, independent report from Khaosod English adds detail Nation Thailand doesn’t cover. Khaosod reports that the app was built with Digital Identity Co. on Amazon Web Services cloud infrastructure, and that first-time users complete the process in under three minutes while returning users take under one minute, since the app retains basic personal data between trips. Khaosod also quotes deputy commissioner Pratchaya directly on a separate goal: cutting time at the immigration counter itself to under 40 seconds per person. Nation Thailand doesn’t include that specific quote, but it does quote Pratchaya on the record elsewhere, on the program’s broader goals. Both outlets independently confirm the trial phase and the officials involved, which is a stronger basis than one outlet simply recycling the other’s copy, even though the vendor details and the 40-second figure trace to Khaosod specifically.
THIM vs. TDAC: These Are Not the Same Thing
It’s easy to conflate the two, since THIM’s entire current function is generating a TDAC. However, they’re governed and required differently. That distinction matters if you’re deciding whether to bother with the app at all right now.
| TDAC | THIM | |
|---|---|---|
| Status | Mandatory since May 2025 | Optional pilot; full launch planned August 2026 |
| What it is | The arrival document itself | A mobile app that fills out the TDAC for you |
| How to complete it today | Government website (all travelers) or THIM app (pilot users) | Downloadable now on iOS and Android |
| Governed by | Thai immigration law requiring arrival registration | An Immigration Bureau technology project, not a separate legal requirement yet |
In short, every traveler already needs a completed TDAC before entering Thailand, with or without THIM. Right now, THIM is simply a faster, optional way to do that same task. It doesn’t add a new requirement on top of the existing one, at least not yet.
What’s Confirmed vs. Still Unofficial
Three things are confirmed directly by Immigration Bureau officials in both reports cited above: the trial phase, the August 2026 full-launch target, and the four launch languages (English, Russian, Japanese, and Chinese). Khaosod English additionally reports a language-expansion target of 15 total languages “by 1 October,” attributed to the bureau. Nation Thailand describes the same expansion as a near-term future plan, without a fixed date attached. The two reports differ slightly on how firm that October date is. Treat it as a likely timeline, not a locked commitment.
Less certain is what happens after August. Officials describe a future “Super App,” according to Nation Thailand’s report. It would eventually handle document requests, immigration office appointments, and a 24/7 tourist police hotline. That’s a stated long-term vision from officials, not a committed rollout with dates attached to any of those specific features. None of it is live yet. Some user reviews on THIM’s official app store listing ask whether the app will become mandatory for tourist visas from October 2026. As of this writing, no Immigration Bureau statement confirms that claim. Treat it as unverified until the bureau says so directly.
Data and Privacy: What the App Store Listing Says
THIM’s official Google Play listing names Royal Thai Police as the developer. Under Google Play’s Data Safety section, which is self-reported by the developer rather than independently audited by Google, the listing states the app shares no data with third parties, with data encrypted in transit. It also discloses that the app can collect personal information along with several other data categories. That scope of collection is expected for a government immigration app handling passport data. Nomads uncomfortable sharing passport photos through a mobile app have an alternative. The standard TDAC website still works and remains available alongside THIM.
What to Actually Do Before Your Next Trip
- You do not need THIM to enter Thailand today. The existing TDAC website still works and remains the default for most travelers.
- If you want to try the pilot, download THIM strictly from the official iOS or Android store listing. A government app pilot is exactly the kind of launch that attracts fake copycat apps.
- Submit your TDAC, through either the app or the website, within 72 hours of your arrival in Thailand. The Immigration Bureau’s official TDAC portal states the form only opens within that 72-hour window before landing, not before departure.
- Recheck official Immigration Bureau channels close to your travel date, especially after the August 2026 launch. A phased rollout like this one commonly shifts on exact dates.
This guide is based on Immigration Bureau statements reported independently by two Thai news outlets, plus the app’s official store listing. The core facts are well corroborated. Still, a pilot program of this kind can change before its planned launch. Confirm current requirements directly with Thailand’s Immigration Bureau or the official TDAC website before you travel. This matters most if your trip falls close to the August or October 2026 milestones above.
Frequently Asked Questions
Is the THIM app mandatory for entering Thailand?
No, not as of this writing. THIM is an optional pilot app that generates the same Thailand Digital Arrival Card (TDAC) all travelers already must complete, currently through the government website. THIM is scheduled for a full official launch in August 2026. However, the Immigration Bureau hasn’t stated that using the app itself will become mandatory.
Does THIM replace the Thailand Digital Arrival Card (TDAC)?
No. THIM is a mobile app that fills out and submits the TDAC on your behalf. It isn’t a separate or replacement document. The TDAC requirement has been mandatory since May 2025 and continues to exist independently of whether you use THIM or the standard website.
What languages does THIM support right now?
The pilot version supports English, Russian, Japanese, and Chinese, according to Immigration Bureau statements reported by both Nation Thailand and Khaosod English. Officials have said they plan to expand to roughly 15 languages. Khaosod English cites an October 2026 target for that expansion, though Nation Thailand describes it simply as a near-term plan without a fixed date.
Can I still use the website instead of the app?
Yes. THIM does not replace the government TDAC website; it’s simply a faster front end for the same form. If you’d rather not photograph your passport through a mobile app, or you’re traveling with a device you don’t want to install a government app on, you can still complete the TDAC entirely through the official website within the same 72-hour window before arrival. Both paths produce the same document, and immigration officers accept either one.
