According to The Hague Convention an “Apostille” is a document such as a diploma or transcript legalized or authenticated for foreign use.
When a document is to be used in a foreign country, it may be necessary to authenticate the notarization or certification. Foreign countries often require documents to be authenticated before the documents will be accepted in the foreign jurisdiction. An "authentication" certifies the signature and the position of the official who has executed, issued or certified a copy of a document.
Basic Apostille Information
The apostille ensures that public documents issued in one signatory country will be recognized as valid in another signatory country. The sole function of the apostille is to certify the authenticity of the signature on the document; the capacity in which the person signing the document acted; and the identity of any stamp or seal affixed to the document.
Some countries require further authenticity of the apostille by the Secretary of State. NIU does include information regarding instructions for Illinois Secretary of State authenticity.
When complete we will mail these documents to the person listed on the form but NIU does not forward documents to the Secretary of State.
