Good morning, my husband and I are currently in Bangkok visiting our son who lives here. We both have visa exempt stamps for this trip. We would like to stay for one additional week, and we are aware of the extension that exempt stamps can get for 1900 baht. Is it possible to do this at the chamchuri building ? Or do we need to go to chaengwattana ? We are both British.
TLDR : Answer Summary
The post asks about extending a visa exempt stamp in Thailand. The general consensus in the comments indicates that the extension should be carried out at the Muang Thong Thani immigration office, specifically at Counter K. The Chamchuri Building is indicated to be for BOI companies and not for tourists. Users are advised to book appointments in advance due to upcoming closures of immigration offices and potential busyness.
