(“Family member” refers to a spouse and/or unmarried children who had not reached age 21 before you entered the DV program.) When adding family members to your case, you will need to upload a document to prove your relationship to the family member being added. 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.
