Form DS-156: NonImmigrant Visa Application Form
This form will be given to the applicant in 2 sets. Both sets are filled up and signed by the applicant prior to his/her scheduled interview at the US Embassy.
For fiancee'/K-1 visa applicants, the embassy includes the DS-156-K forms, but in our case, we only used the DS-156 form.
The DS-157 form (Supplement to NonImmigrant Visa Application) usually comes with the DS-156 in 2 copies as well.
These forms are downloadable and printable online for free. If you think you need extra forms as back ups, you can print many copies as you want.
Just a word of caution: Always download forms directly from the USCIS website.
