Who has such experience to answer the question below?
we have two approved I-140 (NIW and EB1a), we used one I-140 to apply I-485 at the end of June 2007 and got EAD. August 2007, I received NIW approval notice; November 2007, I received EB1a approval notice. I found that my A# in I-485 is the same as EB1a approval notice, which is different from the NIW approval notice. Do you know which one I-140 will be used for the I-485 by USCIS.
Thanks
