Stopover in Chicago: what to do and when to leave
O’Hare combines extensive terminals, immigration, CTA Blue Line and a cautious return to checkpoints. The Loop and Riverwalk are the most concentrated urban exit; avoid spreading a stopover throughout Chicago.
With less than 10 hours, stay in ORD. From 11-13 hours the Loop can fit if you can enter the United States, the baggage is checked through to the final destination and you reserve three hours to return. Millennium Park adds margin.
Your safety comes first. Reviewed on August 17, 2026 · Guidance, not immigration authorization.
