When waiting for something like this the best thing to do is have the mindset that it will be completed within its deadline of 90 days. If it gets done earlier then cool! But don't allow your mind to create an expectation. The completion of these things is very different than a standard application for say a bank loan. These are real men and women looking in extreme detail at the applications of tens of thousands of men and women. Stay positive, but be conservative as to not lose your mind
Processing EADs dated September 15th:
Despite what the USCIS official said, this is unlikely - and easily checked using a status checker app. I'll look into that and update you. I have a friend who has a NOA date of mid-June and only received her EAD this week. I also follow the July and August filers and it seems current processing is predomnantly for late July/early August filers at the moment - although I saw one filer with a date of August 25th who had received their EAD - so there might be a stray case in September already approved. Also expediting based on financial hardship or a job offer coud have caused a September filing date to have already been approved. (My NOA date is September 15th and I am not hollding my breath for my EAD just yet - I am expecting/hoping to have it by new year)
Job offers:
If you have something IN WRITING from a potential employer - with a firm offer of employmment, you can request an expedite. This can take a week or two depending on what the employer has written.
Service request:
From day 75 you can place your request as per USCIS website information. However, we are not outside of 'regular processing times' until day 90. There is a lot of debate on other threads about whether it is best to submit a SR at day 75 or day 90 - because you cannot follow up the request for 30 days after submitting your initial request - so if you submit at day 75 - you have to wait until day 115 to follow up if not received by then. At day 90 you *might* be considered as a more urgent case. However - other threads are reporting that the 90 day 'regular' goalpost keeps being moved. My June filer friend was told that it would need to be past 180 days to be outside of regular processing. She eventually engaged her Senator to push things along.
