FYI - Address change story
I had my application with VSC with a local address which is my company address. All along I stayed at TSC. I had AP twice and EAD once without any problem. The 2nd EAD generated a ref. \'please provide your residential address with proof ( letter, DL etc), not your company\'s address.\' My lawyer sent a letter to VSC about my Texas address and WITHOUT any proof. Got my EAD in two weeks with new address. In 4 weeks I got the approval. My lawyer told me that if your case is very near to processing date and you apply for an EAD/AP, INS may prefer to approve you case rather than printing another set of documents for EAD/AP. I took that chance but I am not sure if that worked for me.
Lastly, after passport stamp , I changed my address once again to a PO BOX address, because I am travelling. Lawyer sent a letter. And after one week I call VSC just to make sure they got the address. I got my card few days back with my PO box address. Hope my story would help you.
