If they are auditioning, make sure to ask what they require you to prepare for your audition. There are no hard and fast rules about when to start auditioning for professional theatre companies. If you have a good photo, a resume with at least a few credits, you've had some positive feedback about your performances and class work, and you feel confidant, go for it. Most professional theatre companies hold a general audition once a year. Call the theatre companies in your area and ask when they'll have their general auditions and what you'll need to prepare for it.

Take them as often as possible. If you have a lot of theatre credits, put some on, but film directors want to see details of your film work first. Make sure your resume photo is very high quality if you're living in a large center where there is a lot of film work. Competition is huge and your presentation must be perfect.
