The persin applying for the visa overseas completes either a DS-260 or DS-160 depending upon which is applicable. The DS-260 is an immigrant visa application and is filed after the immigrant visa petition (usually the Form I-130 or Form I-140) is approved by USCIS. The DS-160 is a nonimmigrant visa application.
