Every person to whom a certificate is issued shall, as a condition precedent to its issuance, and in addition to any other fee which may be payable, pay the initial certificate fee prescribed by this chapter. Prior to receipt of an initial certificate fee, the board may issue an interim permit of a limited duration, but only to candidates eligible for certification under Section 8020. A limited permit shall be valid for 45 days, or until the board issues a certificate to the limited permitholder. If the board issues interim permits, the initial certificate fee, and any other fee that may be payable, shall be paid prior to the issuance of the certificate.
