I have just sent out a I765 renewal application to Nebraska Service Center, and I found mailed to a wrong P.O Box 87485 that handling the concurrent I485/I765 application, but my case is EAD renewal, should mail to P.O box 87765. I don't know if this will delay, or even return my application. Since I already apply the renewal late, only have 60 days left before EAD expires. The time is big concern for me. I don't know if I should mail additonal application to the correct P.O box. If that, do I also need to write another check as application fee? And most important, I don't know mailing out 2 applications will cause any confliction and problem. Really hope any one can help to answer.
