Aircraft
We were being vectored from downwind to base for Runway YY. We were slowing preparing for a visual approach and I called for flaps 1. The pilot monitoring; First Officer; selected flaps 1. The LE SLAT DISAGREE EICAS message and light illuminated. We told the Tower and they gave us vectors around the airport so we could work the problem. I was the flying pilot. I called for the LE Slat Disagree Checklist and the First Officer worked the problem. We also verified the non normal landing distance for flaps less than full. We declared an emergency and asked for Runway XX because it was the longest. The Company was contacted via ACARS in the short time available about our emergency. We completed the non normal checklists and landed on Runway XX without incident. We were able to taxi on our own to the ramp without further assistance. We talked to the Crash First Rescue Commander on a discrete frequency and told him we no longer needed assistance. The non normal was written up in the logbook and maintenance was notified. The First Officer did a fantastic job of managing the checklist and situational awareness during a very busy phase of flight.

A B757-200 LE SLAT DISAGREE EICAS alerted during landing preparations so an emergency was declared. During a vector delay the LE Slat Disagree Checklist was completed; followed by a normal landing.
