PERM Approved but Wrong Past Employment Address

[itsshanks]

I worked at University "A" as Grad Research Assistant under a professor. The professor is now at University "B". So he gave employment letter under the letter-head of university "B" stating that he was my supervisor at university "A". The problem is that my PERM was filed with address of university "B" and I didn't get to see any paper. My boss reviewed it but I don't think that he would know any better and attorney was fairly involved with the process and still did the mistake.

My PERM is approved and I noticed the wrong employment address while signing papers for I-140. Attorney is saying it shouldn't be a problem and we'll attach a letter of explanation. Also not much can be done at this stage other than pulling out the PERM application and re-applying a new one. I believe at this point we're pursuing it as is with a letter of explanation to correct the address on the file.

My question - has anyone been in this situation before and if you know this could be a problem or not?
