Is the 60-day visa exemption still valid for American tourists in Thailand?

Yes, American tourists can still enter Thailand under the 60-day visa exemption, meaning they do not require a visa prior to arrival. There is some confusion regarding 'visa on arrival,' which is not applicable to U.S. citizens. It was confirmed by several commenters that there are no expedited visa services available, as visa processing remains uniform for everyone. Travelers are advised to bring both their old and new passports due to potential inquiries during check-in, especially if flights were booked using the old passport number.
