is it possible to transfer the workpermit to a other company?
and what I need to do, to transfer the WP to a other company?
and if my visa expires, and I make a corona visa extension, is it also possible to transfer my Work Permit?
TLDR : Answer Summary
Transferring a work permit to another company in Thailand is possible, but it involves specific procedures. You need to go through a formal application process to transfer your work permit from your current employer to the new one. Additionally, if your visa is expired and you have applied for a corona visa extension, you should still be able to transfer your work permit, but it's important to verify the regulations applicable at that time.
