Can I extend my visa in Pattaya for 7 days after a 30-day extension?

An American in Pattaya, who has used their 30-day visa-free entry and has extended it once for another 30 days, is inquiring about the possibility of extending their stay for an additional 7 days at Chonburi immigration. Comments suggest that while a 7-day extension may be possible, it might come with a fee similar to that of a standard extension. Additionally, it's advised to prepare for a possible denial of the extension, in which case the applicant would be granted a 7-day leave stamp. Alternatives like obtaining a proper tourist visa through a neighboring country or considering a border run are also recommended.
