Hi , I got study visa in level 8 IT study and landed new Zealand on 29th February. My agent who is IAA applied my wife's case on 7th March and on 10th March we received email that medical is forwarded to medical assessor for assessment, also CO wanted PCC from passport office. Luckily wife's medical was approved on 18th March and we submitted PCC on 20th March. So, my question is How much time will CO take for decision.?
