An apostille is a special seal applied by an authority to certify that a document is a true copy of the original. Apostilles are available in countries which signed the Hague Convention Abolishing the Requirement of Legalization of Foreign Public Documents, popularly known as The Hague Convention. According to the Treaty, a document originating in one Convention country is recognized in all other Convention countries. It bears the so-called "Apostille" stamp, which is a validation performed by the Superior office in the country and state where it was issued. The California Secretary of State provides authentication of public official signatures on documents to be used outside of the United States.
Former students who plan on working abroad may obtain an apostille for diplomas, transcripts, and letter of completion relating to degrees earned.
A requester must submit the following documents to the Office of the Registrar:
- Transcript request form (and applicable fee)
- Copy of the original diploma
- A check or money order for $20.00 (payable to California Secretary of State)
The Registrar prepares a cover letter that certifies the official documents or copies of the documents and the country to which the documents will be presented. Our office will have the documents notarized and will mail them to the California Secretary of State. Your apostille will be mailed back to you from the Secretary of State.
