Travelers’ failure to turn in their I-94 when they leave the U.S. can create a serious problem for them on their next visit to the U.S. If travelers discover that they still have their I-94 when they return home, they should send it to DHS as quickly as possible, along with documentation proving that they left the United States. Documentation to prove departure from the U.S. could include the boarding pass from the departing flight, evidence of arrival in another country (i.e. copy of a passport stamp), or other evidence. Travelers’ I-94 and accompanying evidence of departure should be sent to:

ACS Inc.
1084 South Laurel Rd.
London, Kentucky 40744

Travelers are urged to keep a copy of what they send to ACS Inc. and to carry it with them the next time they come to the U.S. in case the CBP officer has any questions about their eligibility to enter. If they wish to confirm that the I-94 departure was recorded, four months after submitting documents to ACS, travelers can write to the following address with their name, date of birth, passport number, date of departure, and request to confirm whether or not their departure was recorded:

U.S. Customs and Border Protection
Air Sea Passenger Operations
Room 5.4D
1300 Pennsylvania Ave.
Washington, D.C. 20229

Do not mail your departure Form I-94 or supporting information to any United States Consulate or Embassy, to any other DHS office in the United States, or to any address other then the one above. Only at this location are we able to make the necessary corrections to DHS records to prevent inconvenience to you in the future.
