No less than ninety (90) days prior to the expiration date of the license, the Department of Public Safety shall mail to each licensee a written notice of the expiration and a renewal form prescribed by the department. The licensee must renew his license on or before the expiration date by filing with the department the renewal form, a notarized affidavit stating that the licensee remains qualified pursuant to the criteria specified in subsections (2) and (3) of this section, and a full set of fingerprints administered by the Department of Public Safety. A renewal fee of Fifty Dollars ($50.00) shall be submitted along with costs for processing the fingerprints; provided, however, that honorably retired law enforcement officers shall be exempt from this renewal fee. The Department of Public Safety shall forward the full set of fingerprints of the applicant to the appropriate agencies for state and federal processing. The license shall be renewed upon receipt of the completed renewal application and appropriate payment of fees. Additionally, a licensee who fails to file a renewal application on or before its expiration date must renew his license by paying a late fee of Fifteen Dollars ($15.00). No license shall be renewed six (6) months or more after its expiration date, and such license shall be deemed to be permanently expired. A person whose license has been permanently expired may reapply for licensure; however, an application for licensure and fees pursuant to subsection (5) of this section must be submitted, and a background investigation shall be conducted pursuant to the provisions of this section.
