Getting my non-B transferred to my new passport, do I need to go to Chaengwattana in person or can HR do it on my behalf?
TLDR : Answer Summary
When transferring a Non-B visa to a new passport, it is required to go to Chaengwattana in person if you have a valid Non-B visa and are making border runs. They do not transfer visa stickers. However, if you are on an Extension of Stay, it is possible to transfer stamps to your new passport. It is unclear whether HR can act on your behalf for this process.
