Illinois Apostille Service
When traveling to another country for anything other than a vacation, you will often need documents authenticated. But how do you know if you need to follow the process of legalization or apostilization of documents?
The Hague Convention of 1961 determined that all member countries will accept the apostille process, while non-members must follow the legalization process.
Don’t worry if you are unsure which process you need to follow; we know which countries require which authentication.
It is not easy for an individual to apostille a document. In fact, the process of acquiring an Illinois apostille can be difficult when done on your own. That is why we are here to help you.
