Okla. Stat. tit. 36, § 36-2516: Foreign and alien companies

No corporation, company, association or society organized under

the laws of any other state or territory of the United States, or

the District of Columbia, or foreign country shall transact business

under the provisions of this article until it has received from the

Insurance Commissioner a certificate of authority to do business in

this state, a duplicate of which shall be filed in his office. The

Insurance Commissioner shall annually issue to such foreign

corporation, company or association renewal certificates of

authority to continue business, if it shall have fully complied with

the provisions of this article, and if the Insurance Commissioner

shall be of the opinion that any such corporation, company or

association is not entitled to a renewal of a certificate of

authority, he shall cite the same to appear, giving reasons

therefor, and to show cause why the certificate of authority should

be renewed, and unless the certificate of authority shall be renewed

within thirty days after such hearing, such foreign corporation,

company or association shall cease to do business in this state. No

foreign corporation, company, association or society shall be

authorized to transact any business authorized by this article

within this state, unless it can furnish evidence satisfactory to

the Insurance Commissioner that it has a reserve or emergency fund

equal in amount to that required by this article, and the same is

held for the benefit of policyholders only, and invested as required

by the insurance laws of its home state.
