I am currently in the process of trying to schedule an appointment, which is currently unavailable, for an interview for a B2 visa. I intend to visit my sister in the US. In 2020, my husband had won a DV lottery visa and the prospects of going to the US were very high. We filled in ds260s for all family members. Unfortunately Covid happened, and even though the numbers became current, no embassy was conducting interviews. Will the fact that I had filled in a DS260 be a reason for denial? What can I do to improve my chances of success? I only intend to visit for 10 days. I have no travel history.
