What is the I-94W form?
All nonimmigrant visitors seeking entry to the United States under the Visa Waiver Program must fill out an I-94W form (the green form). This form includes specific questions related to inadmissibility issues. If an applicant answers “Yes” to any of the questions on the back side of form, the applicant should contact the United States Embassy or Consulate in his/her country to obtain a visa prior to travel. Travelers must sign and date the I-94W form and must retain possession of the departure portion of the document until leaving the United States.
