What should a U.S. passport holder expect when entering Thailand with Visa Exempt status?

As a U.S. passport holder entering Thailand under the Visa Exempt option, you will not need to complete any specific forms upon entry. You will simply present your passport at immigration, where you will receive a 30-day stamp. It's important to remember that unlike the Visa on Arrival option, which involves filling out an application and paying a fee, the Visa Exempt entry is straightforward and requires no additional paperwork. However, it is advisable to have your onward flights and accommodation details readily available, as immigration officers may ask for them.
