Thanks Bystander6! What I understand is the new rule is the local office will not issue any interim EAD anymore, but they will help you call the NBC or Service Centers to notify them your case is beyond 90 days, and local office will get response in 30 minutes according the memo you sent to me. Then you may get interim card issued by NBC or Service Centers.
However, if you look at the other link about EAD, you will find that people went to local office (just recently) when their case is beyond 90 days and local office did not do any thing about interim card, just told them they do not issue interim card anymore. It is very confusing!!
