Because there was only one space given and "name" was asked. So my parents wrote only my name X and Y.
What would have been your advice If I were in US?
I live in Middle East. I have a question. Let's say my first name Is "X" . My second name or middle name Is "Y". And my Last/Family name is "Z". My birth certificate has my name as "X Y " . All my school report cards and other documents have got the same on them. BUT I want to use my Family name...
