I have a 15 year PE visa renewal coming up, I may take an internal job here in Thailand. How does that affect the PE Visa?
Does it cancel it out entirely or when my work permit ends will I be able to return to PE visa mode?
TLDR : Answer Summary
If you take an internal job in Thailand, your 15-year PE (Elite) visa will not be cancelled. You can transition to a Non-B visa based on employment while still keeping your Elite visa active. The duration of your Elite visa will continue to run down while you hold the Non-B visa. Once your employment ends, you can cancel the Non-B visa, exit the country, and re-enter with your Elite visa without any issues.
