When I apply for a nonimmigrant visa using the online DS-160, are additional forms required?
No, with two exceptions. When applying at a U.S. Embassy or Consulate that is using the new DS-160, Online Nonimmigrant Visa Application, you will use only one (1) form. For Embassies and Consulates that have converted to this new process, the DS-160 has replaced all of the following forms: DS-156, DS-157, DS-158, and DS-3032, which are no longer necessary.NOTE: The exceptions are Fiancee Visas (K-1/2) which still require use of the forms DS-156 and DS-156K, and the Treaty Trader/Treaty Investor visa application, which is explained in #14 below.
