Happy to announce that - On Nov 4, my online status for EAD was changed to "Card picked up by USPS". At this time, my H4 extension online status stayed the same i.e. "Fingerprint review completed".
However, today I received approval notices in mail for both h4 extension and H4-EAD. The notice date is Oct 30.
I hope this information helps others who are waiting for it. We will all soon get these approvals.
