The Diversity Immigrant Visa (DV) program allows people to immigrate to the U.S. from countries traditionally under-represented in U.S. immigration. Each year, up to 50,000 immigrant visas are available through the program. The recipients are randomly selected from the pool of eligible applicants, which averages around 16 million each year. Recipients are eligible for lawful permanent residency (green card status).
Several immigrant advocacy groups have filed a lawsuit claiming that the State Department is deliberately delaying or denying applications by people who won the U.S. Diversity Visa Program lottery. The affected people are from the six majority-Muslim countries covered by President Trump's travel ban -- Iran, Yemen, Syria, Libya, Sudan and Somalia.
