Just an update about the timeline, not sure it will help anyone but it has been like this for me...i765 delivered on 18th June, received sms that the application has been received and is processing with the case number and received i797 in mail on the 1st of June. But from what you guys are saying, it takes some time to receive the EAD card in mail. Hopefully, I can use the notice of action to get employed soon. Good luck to others who are also waiting like me.
