Just read a post about visa extension about the extensions.
We are here on a multi visa from the UK, we have 60 days then we can extend by another 30 before we have to leave the country.
As we have an evisa that we had prior to arrival can we extend this online without having to go to immigration please ?
TLDR : Answer Summary
The user inquired about the possibility of extending their Thai eVisa online without visiting an immigration office. The responses indicate that it is not possible to complete the extension online; a visit to a local Thai immigration office is required to obtain the 30-day extension. Printed documentation of the eVisa is necessary for the application process, and there are additional costs associated with the extension.
