As of this year, 2017, the Labour department have introduced new procedures to the process for new work permits. You will need to submit a one year work plan to the foundation to look at and after approval you will need to get this translated into Thai.
The Thai work plan will be submitted with your new work permit application paperwork. Failure to do this will result in your application not being complete and unable to be submitted. This will result in us being unable to extend your visa when it expires, which means you having to leave the country.
