Kindly Suggest Me, Please.FName, MName and LName

I recieved my H1B visa with the name of "Riaz, Noman Haji ".

Actually, my Passport(Pakistani) has the following informations
SurName: Noman
Given Name : --- (blank)
Father Name: Haji Riaz

while NIC(Pakistani) has
Name :Noman
Father Name : Haji Riaz

My every academic has the info like NIC, that is
Name :Noman
Father Name: Haji Riaz

What i want to know is this H1B visa name is correct "Riaz, Noman Haji"? Secondly, what i have to write in First, Middle and Last Name columns ?
