Since Schedule A is way below EB1a, so it is impossible to try that category for me.
On the other side, as USCIS already accepted our I-485 applications based on the approved I-140 of Schedule A and we finished finger print, I really hope the visa # has nothing to do with our I-485 and USCIS will still work on our case. Is that right?
