Are additional forms required?
No. The online DS-160 application replaced the DS-156, DS-157, DS-158, and DS-3032, which are no longer necessary. NOTE: In addition to the DS-160, Treaty Trader/Treaty Investor visa applicants also must complete an additional form (see the Treaty Trader/Treaty Investor, E Visa Applicants section below for more information). Only applicants for K visas should use the DS-156 application form (see the Visa Categories Not Using the DS-160 section below for more information).
