The I-94 is the Arrival / Departure Record, in either paper or electronic format, issued by a Customs and Border Protection (CBP) Officer to foreign visitors entering the United States. Since April 30, 2013, most Arrival/Departure records have been created electronically upon arrival. Instead of a paper form, the visitor will be provided with an annotated stamp in the foreign passport. If provided a paper form, the admitting CBP Officer generally attaches the I-94 to the visitor's passport and stamps the departure date on the form.
In both circumstances, the visitor must exit the U.S. on or before the date stamped on the form or in the passport.
If a visitor departs by a commercial air or sea carrier (airlines or cruise ships), their departure from the U.S. can be independently verified and it is not necessary to take any further action, although holding on to the outbound (from the U.S.) boarding pass - if they still have it - can help facilitate reentry when coming back to the United States.
If a visitor departs by land and has a paper form I-94, the I-94 must be turned in to a CBP Officer at a land border when exiting the U.S. If it is not turned in to a CBP Officer at the land border, the visitor will be considered an "overstay" and they may be denied entry when they attempt to reenter the United States in the future.
