I just received ITA in last draw and currently I am filling the permanent residence form. In my old passport my complete name was in Given name and Surname was blank. I am currently residing in US on work visa and using First name - FNU and Surname - <My Complate Name>. Recently I got my name split in the new passport and I used the same in my express entry application. My question is do I need to put my name with FNU - Has this person ever used any other name? in the PR form. Is there any other document that I need to submit explaining the splitting of my name?
