Hi ...tried to search for data but cannot find.

Can anyone tell me the process of converting a retirement visa (gentleman not married or has no Thai children) who wants to join our college to teach full time and therefore must have a non b visa and a work permit.

We are in Rayong and immigration says he must get a work permit first but the Ministry of Labour says he must get the visa first.

Any clarity from wise heads here would be helpful. Thank you...
