Beginning in May 2019, Form I-94 will have a new look. The current 11-digit numerical format will be replaced by alphanumeric characters. The new format will include 11 characters, starting with nine digits, a letter in the tenth position, and a digit in the eleventh position.  Customs and Border Protection (CBP) indicated that unexpired I-94 Records issued in the current numeric-only format will continue to be valid until the “Admit Until Date” printed on the paper or digital I-94 Record expires. You can continue to retrieve your electronic Form I-94 here.
