Cal. Ins. Code § 1666

Upon the filing of an application for a license in accordance with Article 4 of this chapter, the commissioner may make such investigation and require the filing of such supplementary documents, affidavits and statements as may be necessary to obtain a full disclosure of such information as will aid him in determining whether the prerequisites for the license have been met. If the applicant makes a showing satisfactory to the commissioner that he meets all such prerequisites, the commissioner, if the applicant be eligible therefor, may issue a certificate of convenience, and upon the applicant meeting any applicable examination requirements may issue a permanent license.
