@bhuntekaji You just need to send the copy of I-797 letter from the approved I-821 and the copy of receipt letter. Send some of the key documents like I-94, SSN, VISA, passport info. Case was an approved TPS but filed the EAD at a later date. Our EAD case approved in around 4 business days. Was quite amazed to see the quick turnaround. Good Luck.
