UPDATE I got my EAD on the mail today.... SIGH FINALLY !!!! so for those who status keep changing dont worry you will get yours soon. Mine changed today to "your card was sent .... and provide tracking number etc" it is so frustrating that they 're giving you a tracking number the day your card is arriving what's the point of it. BUT anyhow... just be patience guys. Here's my time line
