Can anyone explain this to me pls. :
Last time I had a 30 days extention I did it at immigration at Chaeng Wattana.
After a border run I today again visited immigration at Chaeng Wattana for an new 30 days extension, but they sent me to immigration at Lak Si to do it.
Why?
TLDR : Answer Summary
The user initially obtained a 30-day extension at the Chaeng Wattana immigration office, but after a border run, was directed to the Lak Si immigration office for a new extension. Community members explained that the required office may depend on the type of entry visa used, distinguishing between tourist visas and visa exemptions.
