What is the visitor visa requirment for Iranian passport leaving in United States

Hi, Henry, do you intend to apply for it at the embassy or consulate-general in the USA? If so, you should submit a passort valid for at least six months and having at least two blank pages, a photocopy of the passport's info page, a fully filled application form attached with your recent color bare-headed photo, the original and photocopy of your legal stay or residence permit in the US, and round-trip tickets and hotel reservations.
