Thailand's tourism visa rules change on September 15: most foreign tourists will be limited to 30-day stays instead of 60 days, though some bilateral agreements (China, Russia) and reciprocal agreements (Brazil, Peru, South Korea, Argentina, Chile) maintain longer allowances. Private sector welcomes the measure as appropriate for security context, but seeks clearer guidelines on re-entry rules to avoid confusion. Immigration extension at discretion remains, and tourists can still extend within limits.
