请教Pjiang 等大师， porting H1B cap-exempt to H1B cap-subject

Gap problem for H-1B cap-exempt to cap-subject employer

考古了一下发现在H-1B approved 之后如果在十月一号前，严格的说就不能工作直到oct 1st。

However, USCIS does not have a clear rule about the cases after H-1B cap-subject approved for those porting H-1B cap-exempt to H-1B cap-subject.

Does USCIS have new interpretation
or do you know any cases that after H-1B approved the H-1B employee is still working?

Thanks a lot.
