Waiting for H1B Approval

I got my H1B receipt on May 2017 but since then there has been no update on my status. The online portal still says ‘Case has been received’. Its already September and I am bit concerned about my application. Does USCIS usually take this much time?

USCIS case tracker is not working properly better ask you attroney or employer about ur clase status.

I talked to my attorney. They told me to wait till September end.

No. People in my office including myself have thier statuses correct on the USCIS website.
Please check with your petitioner.
