In my honest opinion I think that you should mail it, even though you get the confirmation and receipt# right away. It seems to be taking longer than usual to get your EAD approved through the online option. I filed my EAD since Nov 4, 2003 got biometrics on Dec 17th, still haven't heard anything it's been 4 months now. On the receipt notice it says 90days. I had to get interim ead at federal plaza, nyc.
