I just received notification that my EAD is in production now. Strangely it was 2 months exactly after I sent it in and that is what they said the approximate time it would be for them to review and correct the error. I know this is just a major coincidence but judging by 4justice's timeline it is roughly about 2 months. Mine was supposed to be expedited since it was a birth date issue but I don't believe that 2 months is much of an expedited timeline.
I am just glad it all got worked out finally and hopefully I will receive my card in the mail by the end of this week. Good luck to all of you waiting, maybe yall's wait won't be as long.
