We received a letter in the mail from the US dept of State National Visa Center about two weeks after Mohale’s I-800 approval. Just now we learned that this is all we needed to begin the next step which is filling out the DS-260 form online (Link.) We and our agency are really learning as we go. For anyone following us, you can fill out the DS-260 form as soon as this letter comes from the Visa Center. This letter has a case number assigned to it. Once this form is filled out and submitted, we will simply be waiting on Visa Approval. Once that happens, David can travel to bring him home!
