Documents issued or notarized in Wyoming are apostilled by the Apostilles/Authentications, Wyoming Secretary of State's Office. The office authenticates the signatures of Wyoming public officials — registrars, court clerks, state agencies — and Wyoming-commissioned notaries public, then attaches an apostille for Hague Convention countries or an authentication certificate for all others.
Issues both apostilles and certifications; the request names the destination country.

Federal documents and non-Hague destinations
Wyoming does not apostille federal documents.

For destinations outside the Hague Convention, the Wyoming authentication certificate must then be authenticated by the U.S. Department of State and legalized at the destination's embassy (how the chain works).
