What is the process for transferring my work permit and Non-B visa from Chiang Mai to Bangkok while changing employers?

To transfer your work permit and Non-B visa from Chiang Mai to Bangkok while changing employers, you essentially need to go through a process similar to what you did with your previous employer, as long as it's not the same employer in a different location. You must coordinate between both your old and new employers as well as the corresponding immigration offices. This involves canceling your current work permit and visa extension in Chiang Mai and applying for a new visa extension at the Bangkok immigration office. Although it's complicated, it is feasible.
