Thailand is halving the length of time millions of travellers can stay in the country without a visa. Starting 15 September 2026, the visa-free window drops from 60 days to just 30, a change that will directly affect passport holders from around 60 countries, including the United States, Australia, and the United Kingdom, all of whom have enjoyed the longer two-month allowance since it was introduced in mid-2024.

The update was published in the Royal Gazette on 31 August and effectively rolls back the 60-day exemption that Thailand brought in as part of a wider push to boost tourism numbers. For anyone who’s already booked a long stretch in the country, backpackers on an open-ended route through Southeast Asia, remote workers chasing a warm winter, or retirees settling in for the season, this is a rule change worth checking before departure, not after landing.

Jurgen Himmelmann, co-founder and CEO of Global Work & Travel, says the shift catches a lot of travellers off guard because a month abroad disappears faster than people expect once flights, side trips, and everyday logistics eat into the calendar. His advice is straightforward: if your itinerary runs anywhere near 35, 40, or 50 days, it’s worth reviewing your options now rather than scrambling at immigration.

There’s a cutoff that matters here. Anyone who arrives in Thailand before 15 September keeps whatever stay length is stamped into their passport on entry; the new rule doesn’t apply retroactively. It’s only travellers landing on or after that date who’ll be capped at 30 days under the visa-exemption scheme. According to the Royal Thai Embassy, there is some flexibility built in: the 30-day stay can potentially be extended by another 30 days, though that’s left to the discretion of the immigration officer handling the request, not guaranteed on request.

This isn’t Thailand’s first adjustment to the policy, and it likely won’t be the last. The 60-day exemption itself was only introduced in July 2024 as a tourism-boosting measure, so this reversal effectively brings the rule back closer to where it stood before. Officials have framed the change around a mix of national security screening, tourism management, and broader economic considerations as a reminder that visa-free access, however generous it looks on paper, tends to shift with a country’s shifting priorities.

The practical takeaway is simple: if you have a Thailand trip on the calendar for later this year, don’t assume the rules you read about last year still apply. Check the current guidance from official Thai government or embassy sources, confirm exactly which stamp you’ll receive on arrival, and if your plans run longer than a month look into visa options ahead of time rather than at the airport.
