I do not know the reason

I got nothing after submission I-140 and I-485 concurrently except finger print.I got my I-485 denied directly without any change of I-140 and I485 in uscis website and telephone recorder.I am still waiting for the deny letter of my I-140.So I do not know the reason.But I think they will give only a neutral reason nobody can really understand,just as you go to consulate office to apply a visa and you got a reason of deny nobody can say anything.
