Narrative:

I was speaking to ZBW and they asked which type of approach I wanted. I said 'visual.' they then cleared me for the visual so I started my descent. Boston then asked why I was descending. I said you cleared me. He said yes he did but I could not descend until the airport was in sight. I canceled the IFR and continued my descent.
