Do I need to leave Thailand to obtain a new Non-B visa while my work permit is being processed?

To obtain a new Non-B visa without leaving Thailand, you may have the option to convert a Visa Exempt Entry or Tourist Visa at your local Immigration Office. However, this is contingent on the Immigration Office having the authority to process visa conversions and you meeting certain requirements, such as having at least 21 days remaining on your allowed stay. It is recommended to consult with your employer and visit the Immigration Office together to inquire about the specific process and requirements.
