Apply for PE Licensure by Endorsement
Illinois grants licensure by Endorsement to professional engineers licensed in other states if the licensure process in that state was substantially equivalent to the process in Illinois at the time of licensure.
Applicants will use the forms for Professional Engineer by Endorsement.
Foreign educated applicants must also submit a course by course evaluation report of their foreign education credentials, and TOEFL-iBT (details outlined on page 4 of the PDF).

Register as a Design Firm in Illinois
All employers doing engineering design work in Illinois - even if based outside of Illinois - MUST register as a Design Firm. The only exception to this rule is a sole proprietorship doing business in the EXACT name as is shown on the Illinois PE License. In that case the sole proprietor may only offer services in which he/she is licensed.
In order to complete the design firm registration, the managing agent-in-charge of professional services must be a full-time employee, licensed in Illinois. View the application form for further details on the required composition of the firm for design firm registration.
