Thailand just cut its visa-free stay from 60 days to 30 — here's the number that actually affects your trip
September 18, 2026
On 15 September, Thailand cut visa-free stays from 60 days to 30 for roughly 60 nationalities — Hong Kong SAR passport holders included. Read the headlines and it sounds like a crackdown: less time in the country, an extra fee if you want to stay longer, and a reversal barely two years after Bangkok expanded the same exemption to pull in more visitors. For the Hong Kong traveller booking a week in Bangkok or ten days island-hopping to Phuket, though, the 30-day cap changes nothing — the number actually worth checking before you book is the baht.
What changed on 15 September
Thailand's cabinet had signalled the move back in May; the Royal Gazette made it official, and the new rule took effect 15 days after publication. It unwinds the July 2024 expansion that had lifted visa-free stays to 60 days across roughly 93 countries, including Hong Kong. Thai authorities cited the exemption being used for de facto long-term residency, repeat "visa runs" and undeclared business activity as the reason for scaling it back. Travellers who want more than 30 days can still apply in person at Thai immigration for a single 30-day extension, priced at around 1,900 baht per person — roughly HK$450 at current rates. Add it up and the practical ceiling is still 60 days, same as before; it's just gated behind a form, a queue and a fee that didn't exist a week ago.
Who this actually touches
Most Hong Kong trips to Thailand run four to ten days — a long weekend in Bangkok, a week split between Phuket and Krabi, a Chiang Mai food trip timed around a public holiday. None of that gets anywhere near day 30. The travellers who need to plan around this change are the smaller group doing 45-to-60-day stretches: retirees wintering in Chiang Mai or Hua Hin, condo owners running periodic visa trips, remote workers based out of a Bangkok co-working space. If your itinerary tops out at two weeks, which covers the overwhelming majority of Hong Kong departures, the new 30-day line was never going to bind anyway.
The number that actually moves your trip cost
At the time of writing, one Hong Kong dollar buys about 4.23 baht — near the top of the currency pair's 52-week range of 3.86 to 4.32, and a shade above its 2025 full-year average of roughly 4.28. The baht firmed hard enough this spring to worry Thailand's own tourism authority about pricing out visitors, then drifted back down against the US dollar over the summer; because the Hong Kong dollar tracks the greenback, HKD travellers are catching most of that same tailwind. Put a figure on it: a mid-range Bangkok hotel averaging around 1,800 baht a night runs about HK$425. The entire 30-day extension fee — 1,900 baht — costs less than one additional night in that same room.
The bottom line
If your trip is the standard week-to-ten-days shape, the "Thailand cuts visa-free stay" headline is close to a non-event for you, and the baht's current position against the Hong Kong dollar is doing more for your budget than the new paperwork is taking away. If you're in the smaller group planning 45-plus days, budget the roughly HK$450 extension fee and start the process before day 30 — Thai immigration won't backdate it.
