If you are an AYSO Referee who wants to register with the United States Soccer Federation for the first time, you must fill out both the US Soccer Referee Registration Form and AYSO-US Soccer Cross-Certification Form. Both forms are located on the documents page of this website. Send both completed forms along with a check or money order for $40.00 (made payable to the Nevada State Soccer Referee Committee) for the registration fee to the State Referee Registrar.
