Returning the I-94 or I-94W Form

Failure to turn in your I-94 or I-94W when you leave the U.S. can create a serious problem. Without this record of your departure, you will be identified in U.S. records as an "overstay." Being identified as an overstay means that you will be denied re-entry into the U.S.

If you failed to turn in your I-94 or I-94W, please send it, along with any documentation that proves you left the U.S., to the following address:

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

Documentation to prove your departure can include the boarding pass from your flight. If you exited the country by a land border it is much harder to verify that you did, in fact, leave the country on the date you claim. If you have any documentation of your arrival in your home country (i.e. passport stamp), then you should send a copy of that. If the above office does not have any supporting documents to substantiate your claim to have left the U.S. on a certain date, there is no guarantee that you will be entered into the record as having done so.

We strongly urge you to keep a copy of what you send to ACS Inc. and to carry it with you the next time you come to the U.S. in case the U.S. Customs and Border Patrol (CBP) officer has any questions about your eligibility to enter.

If you want to confirm that your I-94 or I-94W was received by ACS, please give them four (4) months to process the paperwork, then you can write the following address to determine whether or not your departure was recorded. If you turned in the I-94 or I-94W when you left the U.S., as required, please do NOT request confirmation that it is on file. This process is only for people who did not turn in the I-94 or I-94W when they exited the U.S.
