Thank you.
Sorry for the misleading!
Only the I140 got approved.My I485 didn't send out because I didn't think EB1a would work for me.So at the same time of applying the NIW,I just seent out the EB1a I140 as a side product.All the materials are same as NIW,but the petition letter has a little different.
BTW,the NIW I140 is still pending at TSC after transfered from NSC.
