I passed my N400 interview on Jun21-2011, I checked my online case status it appears as below: On June 30-2011, we placed your application in the oath scheduling queue. We will send a notice when the ceremony is scheduled. If you move prior to the scheduled ceremony, please use our Change of Address online tool to update your case with your new address or call our customer service center at 1-800-375-5283.

Thanks for all your help.
