After Expedite request denied, I have reached out congressman office, they help me send offer letter to USCIS through fax. The status of validation error has been lasted for 3 weeks and 2 days. I guess USCIS sent my case to DC for security check. (OPT Security Check) I'm not sure if the congressman office really helpful, but thanks them a lot!!!
Good luck to everyone who are waiting for their EAD card!
