H1b filing center - VERMONT SERVICE

H1b filing mode - Premium


H1b filing date - 06/06/2014

H1B petition received date at USCIS (shown on site) - 06/10/2014


H1b Status as of now (06/18/2014) - Acceptance


I wonder why the status has not changed for so long? People say premimum processing takes 15 calendar days. Even if its RFE will I know the decision only after 15 days? 

And for premium transfer, do they email you the decision for both RFE and approval?
