Hi everyone, Finally after 23 months of waiting, my Office Manager 187 Direct Stream Entry visa has been open. The DHA has come back to me asking for some more documents which fortunately I have and will be providing to them soon. Does anyone know how long does it take to get a response once all the required documentation are provided to the DHA? do I have to wait the 28 days or there is a chance that they will come back to me earlier than that? Cheers
