My Thai wife is a member of our Village Committee, so I sometimes used to get involved, painting, reparing things around the viilage, until a Thai Resident asked why is a Farang doing work, and not a Thai, my wife pointed out that I am a Volunteer, and a Thai would want money to help, that promted me into asking Immigration what, if any work i can do, one officer said if im volunteering then its no problem, another officer 1 month later said i would be subject to arrest, they make up the rules as they go along, be careful
