I have launched my student PhD visa on 25th January, got a reply from IPG case officer on 1st March regarding the assignment of my case. Lately on 4th May, they have confirmed that my application is undergoing standard verification check. They have already received the additional documents ( the same ones which was sent with the application). I have learnt a lot about visa processing time from all of you. Thanks to the forum members for that. Frankly speaking , I did not have any damn idea that NZ PhD visa can take such a long time. Request others to share your views and cases.
