Why living in Kentucky 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 Kentucky Secretary of State in Frankfort has no authority over them, and a state apostille on a federal document will be rejected abroad.
So the process for Kentucky 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.
Louisville: the local details
Louisville is in Jefferson County, within the U.S. District Court for the Western District of Kentucky. Kentucky state documents are apostilled by the Kentucky Secretary of State in Frankfort.
