How to Get an Apostille in Chicago 2026 Guide

At some point, most residents find themselves needing an apostille in Chicago for a job abroad, a foreign university, an overseas marriage, or an international business deal. The process takes one visit or a two-week mail turnaround. But one small mistake in preparation can add weeks to that timeline. This guide will walk you through everything you need to get your apostille in Chicago right the first time - what qualifies, what to bring, and what to expect.

An apostille is an official certification that verifies the authenticity of a document for use in foreign countries that are part of the Hague Apostille Convention. It tells international authorities that your document, whether a birth certificate, marriage record, diploma, or business document, is genuine and legally recognized in the U.S. This makes it crucial for Chicago residents who plan to work, study, or conduct business abroad.

In Illinois, apostilles are issued exclusively by the Illinois Secretary of State - Index Department. Chicago residents can request apostilles either in person or by mail.

Chicago Office: Illinois Secretary of State- Index Department 160 N. LaSalle Street, Suite 100 Chicago, IL 60601 

Phone: (312) 814-8218

Walk-in apostille services are currently available only at the address listed on the official Illinois Secretary of State website. Some websites still display the former Washington Street office, but that location is outdated and should not be used. To avoid delays, always verify the current office address on the official Illinois Secretary of State website before visiting.

Key Points:

• Only documents issued or certified in Illinois are eligible for an apostille in Chicago.
• Federal documents (issued by U.S. federal agencies) must be authenticated by the U.S. Department of State- the Illinois SOS cannot apostille these.
• Foreign-language documents must be translated and notarized before submission. The Illinois SOS does not provide translation services.

• Vital records: Birth certificates, marriage certificates, death certificates, and divorce decrees certified by the county clerk or Illinois Department of Public Health.
• Educational documents: Diplomas, transcripts, and other academic records issued by Illinois schools, colleges, or universities, notarized if required.
• Legal documents: Powers of attorney, affidavits, contracts, and other notarized legal documents issued in Illinois.
• State or local police records: State or local background check records, properly certified or notarized as required.
• Other documents: Business incorporation documents, car titles, powers of attorney, and any other Illinois-issued documents intended for international use.

When applying for an apostille in Chicago, the Illinois Secretary of State's Application for Authentication or Apostille is the official form required. 

Key points:

• Purpose: Certifies documents for legal use outside the United States, covering vital records, educational documents, legal papers, and business records.
• Submission Methods: In person at a Chicago Index Department location or by mail.
• Customer Information: Full contact details required. If submitting on behalf of someone else, their information must also be included.
• Document Information: Include the type of document, issuing authority, and the destination country- this determines whether an apostille or a Certificate of Authority is issued.
• Return Method: You should include a self-addressed stamped envelope for return delivery. If preferred, prepaid courier labels (UPS/FedEx/DHL) may also be used for secure return shipping.
• Payment: $2 per document, payable to the Illinois Secretary of State. Accepted payment methods include check, money order, and credit card (Visa, Mastercard, American Express, or Discover). Cash may be accepted for walk-in service. 

Note: An apostille is issued for documents going to Hague Convention countries. A Certificate of Authority is issued for countries not part of the Hague Convention. Both carry the same fee and requirements.

Getting an apostille in Chicago is straightforward when you follow the right steps. 

• Your contact information.
• Type of document.
• Country where the document will be used.

Step 4: Pay the State Fees

State fees are required per document for apostille processing and are payable directly to the Secretary of State, typically by check, money order, credit card, and others depending on the submission method.

• Walk-In: Documents are processed while you wait, on a first-come, first-served basis.
• Mail: Processed documents are returned via the envelope or courier label you provided.
• Third-Party Coordinator: Globeia tracks your submission and coordinates secure delivery back to you.

The processing time for obtaining an apostille in Chicago can vary depending on the submission method and document type. Key points to consider:

• Walk-in Service: In most cases, processed while you wait, on a first-come, first-served basis.
• Mail-in Service: Takes around 7-14 business days, depending on mailing and return shipping times.
• Third-Party Services: Experienced providers like Globeia can reduce delays and often deliver apostilles faster than standard mail-in submissions, including same-day results.

Note: Mailing and courier transit times are separate from the Secretary of State's processing time and should be factored into your overall timeline. Processing times vary during high-volume periods. Check the current processing time at ilsos.gov before submitting, as timelines are updated regularly.

To ensure a smooth apostille process, avoid these frequent errors:

• Submitting documents that are not originals or certified copies.
• Using documents not issued or notarized in Illinois.
• Attempting to apostille FBI background checks or other federal documents through the Illinois SOS.
• Missing the destination country on the application form- this determines whether you need an apostille or a Certificate of Authority.
• Forgetting to include a self-addressed, stamped return envelope for mail submissions.
• Notarizing documents signed by a Circuit Clerk or Circuit Judge- these must not be notarized; they require only the official seal, signature, and title.
