To use an Illinois diploma or transcript abroad, you must obtain an apostille (for Hague countries) or a certification (for non-Hague) from the Illinois Secretary of State — Index Department, the state's competent authority for authentications.

This guide was reviewed and updated in January 2026 and is valid for 2026.

Who needs it

Typical uses: university admission, foreign work permits, professional licensing, credential evaluation, citizenship/immigration, or HR background checks outside the U.S.

Apostille confirms the origin/signature; it does not evaluate academic content.

What qualifies as a valid school record (Illinois)

For diplomas and transcripts, ILSOS will authenticate Illinois-notarized registrar certifications (or notarized true copies executed by the registrar).

The school official (registrar/principal) signs, and an Illinois notary notarizes that signature; then ILSOS issues the apostille/certification. University registrar guidance confirms the sequence: verify, notarize, submit to ILSOS.

Registrar notarization — how to do it right

  • The registrar (or designated school official) signs a certification referencing the student name, document type (diploma/transcript), date, and page count.
  • An Illinois Notary Public completes a full acknowledgment/jurat: venue, date, notary signature (printed name), commission no./expiry, and seal (if applicable).
  • For transcripts, use an official transcript with registrar certification; for diplomas, many schools issue a notarized duplicate/true copy via the registrar.
Template (registrar certification)

"I, [Registrar Name], Registrar of [Institution], certify the attached [Diploma/Transcript] for [Student Full Name] is a true and correct school record issued by [Institution]. Signed on [Date] in [City], Illinois." (Registrar signature — notarized by an Illinois Notary Public)

Step-by-step process (diploma/transcript)

  1. 1

    Coordinate with the registrar

    Request a notarized registrar certification attached to your diploma/transcript (or a notarized duplicate for diplomas). Universities document this workflow and can assist.

  2. 2

    Complete the ILSOS application

    Download and fill the Application for Authentication or Apostille. Include your destination country, contact info, and return method.

  3. 3

    Payment

    Attach a $2 check or money order per document, payable to "Secretary of State." (You may submit one check for multiple documents; see form.)

  4. 4

    Submit your packet

    Include the notarized school record(s), the completed application, payment, and a return envelope/label.

    Mail (Springfield): Index Department, 111 E. Monroe, Springfield, IL 62756

    Walk-in: Chicago — 69 W. Washington St., Suite 1240; Springfield — 2701 S. Dirksen Pkwy. (confirm current hours on ILSOS before visiting)

  5. 5

    Processing & return

    Walk-in requests are frequently same-day; mail-in typically ~7–10 business days plus mailing time.

When you do NOT need an apostille

  • •If the record is used only within the U.S.
  • •If a foreign authority explicitly accepts a notarized/certified copy without apostille (rare — get it in writing).
  • •If the destination is non-Hague, you may need state certification → (sometimes) U.S. Department of State → consular legalization instead; confirm with the consulate.

Common rejection reasons

  • Missing or incomplete notarization on the registrar's signature (no venue/date/commission).
  • Submitting a plain photocopy that was not issued/attested by the registrar.
  • Wrong address (mail vs. walk-in) or missing return label/envelope.
  • Incorrect fee or payee (must be "Secretary of State").

Frequently asked questions

Do I need to notarize a diploma/transcript before apostille?▼
Yes. For school records, ILSOS authenticates the Illinois notary's certificate on the registrar's signature.
Can Illinois apostille records from another state?▼
No. Each state apostilles only documents issued/notarized in its own jurisdiction.
How fast is walk-in service?▼
Often same-day depending on volume; verify hours before visiting Chicago/Springfield offices.
Where do I get university help with this?▼
Many Illinois universities (e.g., University of Illinois, Loyola, Illinois Wesleyan) provide registrar workflows to verify, notarize, and forward to ILSOS.
