Dear Sirs,
I have been working for Thai company for 8 years, with renewal of work permit and non Imm B visa annually on 21st April.
This year, on 21st of April, my contract with current company finishes, and I start new contract with new Thai company on the same day, so 21st April.
Please can you advise me for the process for change work permit and non Imm B visa over to the new company, and the time scale to start the process of application. I assume I need to renew both work permit and visa on the same day ?
Your advice will be much appreciated
TLDR : Answer Summary
The process to change your work permit and Non-Immigrant B visa to a new employer in Thailand involves adding your new employer to your current work permit, canceling your existing visa, and applying for a new visa with the new employer's documents. It's advisable to coordinate with both employers and the local authorities to facilitate the transition. In practical terms, it may be easier to leave Thailand and re-enter with a new visa after the new work permit is approved.
