How to Get an Apostille in Illinois

If you’re planning to use official documents abroad, you’ll likely need an apostille to verify their authenticity. Whether you need an apostille in Chicago or anywhere else in the state, the process can be confusing—but One Source Process is here to help.

An apostille is a certification issued by the Illinois Secretary of State confirming that a document is legitimate for use in countries that are part of the Hague Convention. Documents not covered by the Hague Convention require embassy or consulate legalization instead.
