Unlike standard mail processing, expedited couriers handle your document physically at every step to ensure speed.
Critical first step. We verify your document is acceptable for an Illinois Apostille (correct signature, not federal) to ensure it can be processed.
Your document is physically hand-carried to the IL Secretary of State in Springfield or Chicago. Counter service is first-come, first-served. Only $2/doc!
Once processed, your apostille is picked up from the office. We verify the seal is present and correct, then arrange return shipping.
Recommended for urgent deadlines where a 4-6 week wait is not an option.
Moving or traveling within 2 weeks? The mail queue is too risky for such tight apostille deadlines.
For mergers, court dates, or POA filings requiring strict same-day authentication.
