Narrative:

We were inbound on the bfi 13R localizer. Prior to the FAF we noted an aircraft approaching our flight path. A TCAS RA to 'climb' was subsequently issued; autopilot disconnected and RA guidance followed and we climbed approximately 250 feet above altitude where RA was issued. We immediately notified ATC and then resumed the approach to an uneventful landing. With all the general aviation traffic in the area; this is a recurring issue when landing at bfi. Flight crews might want to delay accepting a visual approach to keep ATC's separation criteria.
