Narrative:

While being vectored by new york approach; we were given a turn while at 3;000 feet. Approach pointed out traffic; and we were visually searching while in and out of light snow showers. Approach issued us a turn and a climb to 3;500 feet as the other aircraft appeared to be climbing. We started the climb when our TCAS issued a 'descend now' command. At the same time we had a visual on the cessna and continued to climb; but climbed to 3;800 feet as the cessna was too close for our liking; approximately 500 feet below at that point. After clearing the traffic; approach issued us a turn and we inquired what altitude they now wanted us at. We were given 2;000 feet and we descended.
