Your Path to Membership​

As part of completing your membership application you will schedule a video-conference interview with a representative of the membership committee. If your application is supported by the committee and your membership fee paid, the CSA will undertake a negative-vetting background check and security clearance. This to protect the integrity of our membership. Security clearance is often required for diplomatic-level CSA Experiences. If your application is not successful, your membership fee will be refunded.
