I missed my oath ceremony in May 2018 since the notice never arrived. I wrote USCIS explaining my situation and requesting for my oath ceremony to be rescheduled. I hope they understand that missing the originally scheduled ceremony was not my intention and fault. I confirmed that my address on file is correct and I have received all notices in the past. I tried meeting USCIS twice through Infopass appointment but was simply told to wait. Is it normal? Should I expect to have to reapply? Is there anything else I can do?
