An authentication or apostille certifies the authenticity of the signature,
seal and position of the official who has executed, issued or certified a copy
 of a public document. An authentication or apostille enables a public document
 issued in one country to be recognized as valid in another country.
An apostille is a certification form set out in The Hague Convention Abolishing
 the Requirement of Legalization for Foreign Public Documents (1961). 
The apostille does not validate the substance, contents and/or legal effect of the
 document, nor does it imply that the document has been approved and/or endorsed
 by the Oregon Secretary of State. The Office of the Secretary of State does 
not regulate what documents are required by the foreign country. 
To verify the required documents, contact the embassy of the country to
 which you are submitting the documents.
