UPDATE: Subject of needing "Mananging Director" in the Work Permit to get a One Year B Visa Multi-Entry.
My Business Assistant Khun Pam who is very sharp in these matters, called Krabi Labor Ministry about the phrase "Mananging Director" versus just "Director" typed in the Work Permit. The Labor Ministry Officer said they normally only put in "Director" but would change a Work Permit booklette to read "Mananging Director" upon request.
Also Khun Pam called the Kota Bharu Consulate to see if this supposed requirement had spread to Kota Bharu.. The Consulate officer replied that this wording of "Managing Director" was not a requirement in their office. The officer also added that she has not heard of this issue.
(this is not to say that my post is policy in all of Thailand or of all Thai Consulates - and things may change)
TLDR : Answer Summary
The post discusses the recent updates regarding visa requirements for foreigners in Thailand, specifically focusing on the title needed on a Work Permit for obtaining a One Year B Visa Multi-Entry. A call to the Krabi Labor Ministry revealed that while 'Director' is typically sufficient, they can amend it to 'Managing Director' upon request. Furthermore, inquiries with the Kota Bharu Consulate confirmed that this terminology is not mandatory there. Several forum users shared experiences regarding title requirements for work permits, with some reporting instances where 'Managing Director' was indeed required.
