Why did I only receive a 30-day visa exemption instead of the expected 60 days upon my arrival in Thailand?

A recent traveler to Thailand anticipated receiving a 60-day visa exemption but was only granted a 30-day exemption. This discrepancy arises from the fact that the proposed new rule had not yet been officially implemented, as it must be published in the Royal Gazette to become law. Various comments from other travelers reflect a general understanding that the changes might be approved soon, but they are not yet in effect. Therefore, travelers should prepare for the possibility of receiving only 30 days until the official stance changes.
