Please help!

I need your help. I filed two applications (EB-1 and EB-2 (NIW))to CSC with concurrent filing 485 that was attached to NIW. My EB-1 was transfered to TSC in March and it was approved recently, so I want to transfer my 485 to EB-1. I would like to know whether you guys have some similar situations. If so, please share your experience.

Thanks,
