Sharing my experience.
Find my below stamping time line.
DS-160 : updated about DV case and added note about having certified court letter and police report.
Went to Vietnam for stamping.
Appointment 9th April
Consular asked about general employer questions and about pay
Then asked about DV case and once I explained my case he asked about supporting court document and only gave court dismissal document.
Officer said he can’t approve Visa as the document need verification which is eventually show visa refused the next day in ceac site which is a 221g and since document is already submitted they won’t give any 221g form or slip.
Consular said it may take 3-4 days to approve your visa after verification and kept my passport with court document.
I waited for almost 10 days and Visa got approved and received the passport and travelled to US.
