Surname field is blank in my passport. My full name is in "given name", so will that be a problem while applying for a study visa to Australia?
My actual name:
surname: Ganta given name: Dheeraj
surname: given name: Ganta Dheeraj
No, it won't be a problem. This is a common enough situation that visa processing officers will have seen it before, just enter your names exactly as they're listed in the passport.
