No status after application was received at USICS

I am applying for the first time for a H1B, My application was received on Apr 06 2015, but there is no status or the reference number, when will i get the reference number to track my application status?

could someone help me with the steps that will happen after USICS receive the application

How are you checking the message “My application was received on Apr 06 2015”?
Are you using a WAC or EAC number? If yes, than thats your receipt number to used to check your application status. Application Received is usually the first step. I am thinking that you applied Premium Processing, and hence received the receipt number so soon. Just keep checking your status on the uscis website. Also, you can subscribe to status changes if you make an account on the uscis website.

Good luck.
