Narrative:

On approach to 27L in ord we had to do a go-around due to the fact that the flight in front of us did not exit the runway in a timely manner. They attempted to ask the controllers if they could exit the runway on 4L but received no response so they had to continue to H1. ATC called our go-around at approximately 100 ft. We accomplished the go-around with a quick right turn out due to traffic departing 28R who were also in a right turn out. We got a quick vector back around to 27L for a visual and landed without incident.
