The I-94W Goes Paperless
During the month of July 2010, the I-94W for Visa Waiver Program (WVP) travelers entering the United States by air or sea is being phased out. Please check with your carrier for further information. Travelers who do not complete the I-94W will have their period of admission written into a stamp in their passport.
The I-94W form will continue to be used by travelers entering the United States by land and the I-94 by travelers entering the United States on valid visas.
