Due to the Automation Process started by Customs and Border Protection (CBP) from 30th of April, 2013, USCIS has begun updating certain forms requesting applicants and petitioners to enter the admission number from their Form I-94 and/or their:
- Passport information, including passport number, country of issuance and expiration date; and
- Travel Document information, including Travel Document number, country of issuance and expiration date.

So, prior to this automation, the Form I-94 which was given to you by the airline staff to fill up and submit it to CBP at the port of entry, is not needed anymore.
You can pull your electronic Form I-94 in paper format from CBP’s website (www.cbp.gov/I94).
