First of all, this is the only section we have to finish. We have consulted a lawyer, unfortunately this lawyer did not help us at all with this doubt we have. And hopefully we'll find some answers here. So let's get started: ON the Form DS-260 asks us about work history over the past 10 years. My husband has worked in the construction field for these ten years and has had a variety of projects. Some projects were owned by private companies and others by large companies that he remembers. The question we have is: How do you refer to the number and address of a company that no longer exists (or that you no longer remember) on the DS-260 application? I hope this makes some sense to you. We are at this point very desperate. and we have no other option since lawyers are very expensive.
