Why living in Oklahoma doesn’t change the route
This document is issued by Internal Revenue Service, a federal authority. Federal documents are authenticated only by the U.S. Department of State in Washington, D.C. — the Oklahoma Secretary of State in Oklahoma City has no authority over them, and a state apostille on a federal document will be rejected abroad.
So the process for Oklahoma residents is the same as for anyone else in the country: get the document to us, we hand-deliver it in Washington, and it comes back ready to use.
