I submitted mine and my wife's I-485 (please see signature) on 04/17/2007. Today our I-485 checks were cashed and I was able to get the case number from the back of the check. So, the LUD on both of our I-485's is 04/19/2007. However, I also see a LUD (04/18/2007) on my already approved I-140. Is this normal? Is this how it happens? Please give your helpful suggestions. Thank you very much.
