Currently (since 2007) living with my wife in Thailand on over 50 retirement extensions to OA visa. Shortly I will be working for a Vientiane based Engineering project in Laos on business visa with work permit.
My role will most likely include inspecting and quality control on Engineering elements sub-contracted out some of which quite possibly to include Thai Companies.
Will I need a different Thai visa and work permit for visiting/inspecting the work progress/quality in Thailand.
