I'm working on a TV show in the USA that centers around a host that travels to experience various jobs. For an upcoming episode our host will be going to Canada to temporarily work a job. During the production period, he'll be working for a company in Canada, and at the same time working for the TV show. When applying for a temporary work visa for our host, do we list the job he'll be doing with the Canadian company, or do we list the TV job, or both?

It would seem that the fundamental role that the individual is filling is that of a (reality) character in the television show. The specified occupation should therefore be such, but the description of the role would have to include the task that will be carried out in the occupation the character carries out in Canada.
