Addendum
Forgot to mention few other details. I have seen people asking questions like "Do we need to give just one check or seperate checks for filing EAD Renewal when filed for primary and spouse"... What I did was to enclose both the packets (applications) in one FedEx Envelope and wrote only one check.
I got the packet back saying that the amount is not the right amount, so I again wrote (correct amount this time) one single check for 2 applications and sent it back to BCIS. On May 20th, spouse's case approved and mine is still pending. Our EADs expires on May 29th.
Please let me know if anyone has any further questions.
