From Initial Review to Acceptance when I changed my preference?

My application was selected in the lottery and I received my notice receipt on 25th. My status under RP/RQ was Initial Review, then I changed to PP and it has been on at Acceptance for the last 3-4 days. What could be the reason?

Hi Kumar,

It is obvious for you application to go back to acceptance stage as from RP bucket your application is transferred to PP bucket. Dont worry , just keep an eye on the status.
