Narrative:

While descending through 10000 ft with clearance to cross rbv VOR at 8000 ft, we encountered a TCASII RA alert to stop descent and climb. We complied with alert, noting a red square TCASII icon at our altitude concurrent with a visual acquisition of non-communicating VFR traffic at our altitude laterally separated by approximately 300-500 ft. Reported near miss to ny approach.
