Departure Record Form I-94 Return
If you left the United States with your I-94 card that was given to you when you last entered the United States still in your possession, your departure was not recorded properly. If you do not correct this record, or if you cannot reasonably prove that you departed in a timely way when you next apply for admission to the United States, the Department of Homeland Security (DHS) may conclude you remained in the United States beyond your authorized stay, which may adversely affect your qualifications for a nonimmigrant visa in the future.
If you failed to turn in your I-94, please send it - along with any documentation that proves you left the U.S. to
DHS - CBP SBU
1084 South Laurel Road
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 the address above and to carry it with you the next time you come to the U.S. or apply for a visa in case there are any questions about your eligibility.
