“Case Was Reopened”on your N-600 · Proof of citizenship through parents


USCIS reopened your N-600, often after a motion or appeal. Your certificate request is pending again. Watch for a new interview notice or a request for evidence. Keep your parent's citizenship proof and your birth record handy, since the officer may ask to see them again.
In general, on any form:
USCIS reopened your case after it had been closed or decided. This can happen after a motion, on USCIS's own initiative, or to fix an error. The case is active again and will get a new decision. Read any notice that explains why.
