My H1b was denied and I applied for MTR. My H1b finally got approved on Dec 12th. My employer received I797C approval notice with valid dates. I haven’t received my original documents yet, not sure how long it would take to receive them. Please let me know if there is any way that I can know my COS is also approved? I am currently enrolled in a school. Now due to this H1b approval, will my SEVIS be automatically terminated? If it is terminated, does it mean my COS is approved? Please confirm.
