I mailed in my wife's I-751 along with the supporting documents on Thu. via USPS Express mail to the Nebraska Service Center. WE made sure that we had all the required supporting documentation but forgot to check for the most obvious of things - signature!!! My wife forgot to sign the form!! I just called the USCIS 800 # and they said I have to wait until the application is rejected or a letter sent asking to resubmit. Does anyone know if NSC has a fax #? Should I just go ahead and mail the signed form to USCIS along with a cover letter explaining the situation?
