Asking for a friend.
The guy got a project in samui for next April. Hes got specific dates and need to bring himself and 4 of his staff.
It is only for 3 weeks and he doesn't have a Thai company. What visa options he got to make it legal?
Can he be invited by the company that offered him the job? Is there any short term working prmit for spcipic dates?
TLDR : Answer Summary
A person and his four staff members need to work in Koh Samui for a specific project lasting three weeks without being affiliated with a Thai company. The recommended route is to obtain a Non-Immigrant B visa, which allows for short-term work, supported by an invitation from a registered Thai company. Depending on their nationalities, they may need tourist visas if not eligible for visa exemption.
