H1B Ext. PP......no response yet..

[Aarav27]

My employer submitted H1B Ext. in PP to Nebraska SC on Sept 20*and application received on Sept 22.

Got the receipt # via email and cheque was cashed.*
However, USCIS website*says that they received my packet on Sept 26.

Still its more that 15 calendar days and have not received any response.

Any thoughts?

Thanks in advance.
