No, i didn't use a lawyer. Filed everything on my own. There wasn't supposed to be any other address. I have moved but I've filed AR-11 when I did.
Customer service wasn't of much help either. They basically told me either wait for someone to get back to me regarding the e-request I submitted a month back, or file a new I-765 (which would take months of processing time and seems as a totally useless advice on their part)
