Just had my N-400 interview and was recommended for approval, but there is a system issue and my file cannot be sent to wherever it needs to go. The interviewer told me they'd submit a ticket and that I could wait for it to be cleared so l could have my ceremony today or just go home and come back at a later date. So far it's been two and a half hours and no updates. Has anyone had something similar happen to them? Super bittersweet moment for a day that was supposed to be happy!
