In my parents' cases, they got their EAD the same day they submitted their applications--they submitted in AM, and EAD done in PM in the local office. They were also asked to do their fingerprints for both I-485 and EAD the next day at the local document support center (the officer write them a fingerprint request form). This happend last Sept.. Now 6 moths later, the INS sent them another notification for fingerprints, but theirfingerprints are in file and complete already.....just want to see if similar things happen to some of you guys.
Also a reply to the messager waiting for fingerprint notice for I-485---I think you need to find out from your local office why a request for I-485 fingerprint has not been issued----Normally they issue this the same time when you submitted your application.
