I'm reading instructions to U.S. Diversity Immigrant Visa Program (https://www.youtube.com/watch?v=tOQlh2d2EbQ&feature=youtu.be, http://travel.state.gov/content/dam/visas/Diversity-Visa/DV-Instructions-Translations/DV-2016-Instructions-Translations/DV_2016_Instructions_English.pdf).
It states:
Be sure to include:
- all living natural children;
- all living children legally adopted by you;
- and, all living step-children who are unmarried and under the age of 21 on the date of your electronic entry, even if you are no longer legally married to the child’s parent, and even if the child does not currently reside with you and/or will not immigrate with you.
I can't get last list item: how can I have a step-child if I'm no longer legally married to that child’s parent?
