My father writes his name as "Vijai Shanker" and his passport shows "Vijai Shanker" as his First name and the surname field is left empty.
Now, if i put the same info in the form DS 160, it does not accept it as Surname is a Mandatory field in the form.
What shall i do? Shall i mention Shanker as his surname ? Will that be a problem as it would mis-match with what is there on the passport.
by the way, I'm applying for his tourist visa.
