Hello,

Since, you asked this question few months back, I don't know about the status of your admission, still want to inform you that IGNOU has its overseas partner, you need to contact them regarding this entire admission procedure, and they will take you through this. 

I'm attaching the link of the official website of IGNOU, you may consider going through it, this one is specially for International Students, it will clarify all your doubts-
