Can I extend my 60-day tourist visa at Laksi Square and what are the potential holiday impacts on my visa extension?

The user inquires about extending their 60-day tourist visa in Thailand, specifically whether they can do so at Laksi Square as they did previously for their 30-day exemption stamp. Additionally, they seek information on Thai holidays on December 7th and 8th, and if they can visit the immigration office on the following Monday after their visa expiration on Saturday, December 9th. Responses clarify that extensions for a tourist visa are processed at the Chaengwattana immigration office, not Laksi Square. The importance of visiting before the holiday period is also stressed due to potential delays.
