Is this a REF?

NIW 140 submitted 19 monthes ago,We moved in this Feb and noticed the service center.
Then we got the email"On April 27, 2005, we responded to your request for more information concerning your case. If you have not received our response within 30 days from this date, please call customer service" I wonder is this a Ref or because we moved, so they need more info. Thank you for your reply.
