Narrative:

During approach to okc ATC gave us a TA for VFR traffic 10 O'clock position at 7500 ft (our altitude 8000 ft) not talking to ATC. We got a TA followed by RA that told us to climb. We climbed clear of conflict to 8500 ft. Queried ATC if they wanted us to return to 8000 ft. They gave us a vector and descent to 6000 ft. TCAS was showing intruder aircraft minus 300 ft.
