I am applying for a Treaty Trader/Treaty Investor, E Visa. Do I need to fill out the DS-160 and the DS-156E?
It depends. If you are a Treaty Investor (E-2) applicant, you need only complete the DS-160. If you are a Treaty Trader (E-1) or an Executive/Manager/Essential Employee (E-1 or E-2), you must complete the DS-160, and you or your employer must complete the paper DS-156E form.
