H1 and H4 filled together H4 receipt received

Hi,

My employer has filled my H1B visa on May 31, 2012. They told me that they have filled my H1 and H4 visa together.

On June 4 we have received a receipt number for H4 visa filling from USCIS but I am still waiting for the H1 receipt.

Does this mean that USCIS has received and processed both the applications and they are taking time to send the Receipt number for H1 case ?

Or my H1B is not filled with them only H4 got processed ?

Yes, they have accepted both and will soon send out the petitions. H-1 receipt is send to employer/attorney.
