Why living in Colorado doesn’t change the route
This document is issued by US Citizenship and Immigration Services, a federal authority. Federal documents are authenticated only by the U.S. Department of State in Washington, D.C. — the Colorado Secretary of State in Denver has no authority over them, and a state apostille on a federal document will be rejected abroad.
So the process for Colorado 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.
Denver: the local details
