Is Nigeria visa open now

We would like to inform you that granting a new visa to a holder of Nigerian nationality, and due to the corona procedures on granting the visa, it may not be possible to obtain a new visa for reasons related to security approvals, and this is what the state authorities reject without giving any reasons.
Therefore, you can try to apply for new visa by Emirati sponsor who handles extracting it for you after obtaining the NOC and canceling the old visa.
