For context, here's the time line:
My EAD expires mid October
USCIS received my renewal docs on June 17, 2014
I had my biometrics in mid July

And today, I received this notice attached below. It's a I-797C Notice of Action telling me that my EAD is set to expire within 100 days and that I should reapply soon (which I did!). It does say that I can disregard the notice if I already reapplied, but I'm just concerned because it seems weird to get a notice like this when I already did my biometrics. Anyone else get something like this?
