Form I-94, the Arrival-Departure Record Card, is a form used by U.S. Customs and Border Protection (CBP) intended to keep track of the arrival and departure to/from the United States of people who are not United States citizens or lawful permanent residents (with the exception of those who are entering using the Visa Waiver Program or Compact of Free Association, using Border Crossing Cards, re-entering via automatic visa revalidation, or entering temporarily as crew members).
This could be due to missing documentation, need for further review of the case, need for a maintenance of status and departure bond, or other similar reasons.
The process of admission of the alien and issuance of a long-term Form I-94 is then completed at the deferred inspection site.
This applies to two main types of forms:[2] Note that for students on an F visa, the I-94's expiration date is listed as "D/S", for duration of status.
In September 2016, CBP announced the availability of electronic Form I-94 at land ports for travelers who registered in advance and paid a $6 fee.
