Illinois Apostille Service

When traveling to another country for anything other than a vacation, you will often need to provide the necessary documents. And each of those documents must be authenticated.

An apostille or embassy legalization is a process that verifies the authenticity of the stamps and signatures of a document. In fact, the word ‘apostille’ is French for ‘certification.’

The Hague Convention of 1961 determined that all member countries will accept the apostille process, while non-members must follow the embassy legalization process.

Don’t worry if you are unsure which process to follow; we know which countries require which authentication.

The authentication process can be tricky. In fact, acquiring an Illinois apostille can be difficult when done on your own. That is why we are here to help you.

Let Us Handle the Illinois Apostille Process

You must follow each step of the process for obtaining apostilled documents perfectly, and all paperwork must be error-free. Even the slightest mistake can cause the apostille to be delayed or rejected.

First, you must determine if you have a state-issued document or if it is federally-issued. This will decide who you contact to receive an apostille or embassy legalization.

Examples of state-issued documents are:

  • Birth certificate
  • Death certificate
  • Driver’s license
  • Articles of Incorporation

Examples of federally-issued documents are:

  • FBI background check
  • Passport
  • Social Security information

For state documents, you will work with the Secretary of State in Illinois; and for federal documents, you must contact the US Department of State in Washington, DC.

And if your destination country is not a member of the Hague Convention of 1961, you will then contact the Embassy or Consulate for authentication.

Remember, each document must have its own apostille. So, when working on your own, you must submit an apostille application for every document that requires authentication. No blanket apostille covers several documents at once.

At One Source Process, we know the steps to have your documentation quickly and easily receive an apostille from the appropriate office. We will contact the Illinois state department, the federal department, and the Embassy or Consulate when necessary.

Our Quick and Easy Process

When applying for an apostille on your own, you must determine which governmental office to contact and submit your apostille application form. Sometimes there are several departments to work with.

We understand that you are busy. That’s why we made working with us to apostille or legalize your documents as easy as 1-2-3.

  1. To begin, simply fill out our Order Form This is where you tell us what you need and which country requires the apostille.
  2. You will then send us your original documents (or a certified copy).
  3. Once we have confirmed that all documents are correct, we will send you a payment invoice and timeline for completion.

That’s it!

You will be assigned a dedicated agent who will work to obtain your apostille. This means someone will watch your paperwork throughout the entire process, ensuring there are no problems. And if you have any questions, you can call and speak to one person instead of being passed from customer service representative to representative.
