Form I-94W – Nonimmigrant visa waiver arrival/departure record is no longer required to be completed when arriving by air or sea to the United States.
A Customs and Border Protection (CBP) officer will stamp the applicant’s travel authorization with their admission/departure date and their class of admission, after the border inspection has been successfully carried out.
Those who need to prove their status as legal visitors to any U.S. institution that might require it, may access the I-94W form information online. Furthermore, the original I-94W form can be requested during the inspection process at the U.S. border. Note that those travelers who have been given an admission/departure I-94W form must surrender it when leaving the States.
