It lists us as your Oklahoma registered agent, next to your Illinois name and formation date. If Oklahoma wants the Illinois certificate, it is ordered first. Once Oklahoma approves it, the Illinois company can do business there.
Will your Illinois name work for Oklahoma?
We search Oklahoma's records for Illinois's name on file before anything is filed.
Your Oklahoma agent and the Illinois one
Illinois and Oklahoma both call it a registered agent. Oklahoma papers come to us; Illinois's agent is unchanged.

Does Oklahoma require a registered agent?
Yes: the Illinois registered agent stays, and ours covers Oklahoma for year one, with a street address there.
Can I form a new Oklahoma corporation instead?
Yes, but Illinois keeps the original, so you run two companies: the new one has no Oklahoma yearly report, and the original keeps Illinois's Annual Report (Form BCA 14.05).
How do I withdraw from Oklahoma later?
Illinois companies leave by filing a Certificate of Withdrawal (Foreign Corporation); until then, Oklahoma's report stays due alongside Illinois's filings.
