Wyo. Stat. § 13-2-213
If the application is approved and a charter granted by the board, the financial institution shall not commence business before receiving a certificate of authority to operate from the state banking commissioner. The application for a certificate of authority shall be made to the state banking commissioner and shall certify that the capital and surplus have been paid in, the address at which the institution will operate and that all of the bylaws adopted have been attached as an exhibit to the application. The application shall state who the officers, directors and stockholders are at that time and have attached evidence that appropriate federal insurance of deposits has been obtained, where applicable. The state banking commissioner shall approve or deny an application for a certificate of authority within thirty (30) days after the application has been filed, but the authority of the state banking commissioner to disapprove any application is restricted solely to noncompliance with this section. If the state banking commissioner approves the application, he shall issue a certificate of authority to the organizers within twenty (20) days. If the state banking commissioner denies the application, he shall mail a notice of denial to the organizers within twenty (20) days, stating the reasons for denying the application, and grant to the organizers a maximum period of ninety (90) days to resubmit the application with the necessary corrections. If the applicant fails to comply with requirements of the notice of denial within ninety (90) days from the receipt of the notice, the approval of the application and articles of incorporation previously issued to the applying institution shall be revoked by the state banking commissioner. The failure of the state banking commissioner to act upon an application for a certificate of authority within thirty (30) days shall be deemed an approval. If the approved institution fails to commence business in good faith within one (1) year after the issuance of a certificate of authority by the state banking commissioner or any required federal approval, whichever is later, the charter and certificate of authority shall expire.
