Using casting director visits is a common way for local companies to make money, or out of town companies to attract and keep students, clients, actors and most important additional funds to their profit line. The truth is that most of those "casting directors" are simply earning extra bucks, and are in violation of the rules and ethical codes of the Casting Society of America (CSA). Except for established actors requested by the producers, these casting directors expect talent to live in LA or the city where they are casting an actual project to be considered for roles
For those who are tempted to pay big bucks through agents, "studio's", schools or so called "rehearsal spaces" here in Nevada, please read the California legally required disclaimer whenever casting directors do a seminar or appearance involving actors:
"This is not a job interview or audition. The presence of a Casting
Director is neither a guarantee nor a promise of employment. The intent of the class is solely educational. Attending a workshop is not a way to obtain employment as an actor. Such contact as you may have with a Casting Director at a workshop rarely results in any further contact with that Casting Director or any company affiliated with that Casting Director."
