InfraGard membership starts at the national level. National membership is free, but you must gain acceptance by the FBI. You must apply for membership on the national InfraGard website. You specify your desired local chapter in this application:
Once you are approved for national membership, your information is given to your selected local chapter. We will then notify you with information on how to complete your local chapter membership. Our chapter pays yearly dues of $20, which will need to be submitted before you may attend some of our events.
