Foreign visitors arriving to or departing from the U.S. receive electronic travel records, I-94 from Customs and Border Protection (CBP). Currently, I-94 numbers are 11 digits long and only contain numbers. In order to minimize program impact resulting from the depletion of numeric-only I-94 numbers and to create a long-term solution for the creation of new numbers, CBP is switching to alphanumeric I-94s beginning in May 2019. I-94 numbers will remain at 11 characters but will follow the format of 9 digits, followed by a letter in the 10th position, and a digit in the 11th position. Unexpired I-94s issued in the current numeric-only format will continue to be valid until the Admit Until Date printed on the paper I-94 and/or the date displayed on the public I-94 website at https://i94.cbp.dhs.gov/I94/#/home.
If you are a foreign national entering the U.S. temporarily, as soon as you are admitted, please log on to https://i94.cbp.dhs.gov/I94/#/recent-search, enter in your travel information, and print your new I-94 record. Please ensure that your Form I-94 is accurate: name, visa category, and expiry date. CBP can make mistakes since they are officers entering the data.
