No surname and given name exceeding the text size in DS160 form.

Hi all,

I am trying to fill DS160 form for applying for H4 visa.

I am facing 2 problems

1)No Surname in the passport

2)Given Name field is exceeding the text size allowed in the DS160 form.(As First and Last name both are present in the Given Name field)

Can someone suggest me best possible solution to cater the problem?
