For the relevant traveller scope, is a visa, electronic authorisation, visa on arrival or no advance visa normally required?
Generally a visa is required: the visitor (B-1/B-2) visa is a nonimmigrant visa for temporary entry for business, tourism or both. The official source does not state which travellers are exempt from the visa requirement.

Generally, a citizen of a foreign country who wishes to travel to the United States must first obtain a visa, either a nonimmigrant visa for a temporary stay, or an immigrant visa for permanent residence. Visitor visas are nonimmigrant visas for persons who want to enter the United States temporarily for business (B-1 visa), for tourism (B-2 visa), or for a combination of both purposes (B-1/B-2 visa).
