If your family circumstances have changed after you entered the Diversity Visa program, for example, if you have gotten married or had a child, you will need to add your new family members to your case.
You will need to enter your DV case number into the online DS-260 form to access and update the information about yourself and your family that you included in your DV entry.
The principal applicant and all family members applying for a diversity visa program must complete Form DS-260.
