CBP DOES AWAY WITH I-94S

U.S. Customs and Border Protection (CBP) started implementing the automated version of Form I-94, Arrival/Departure Record, at air and sea ports of entry. Implementation will continue across the nation through May 21, to include air and sea ports of entry that support international arrivals.
CBP will stop giving away I-94s and instead stamp each foreign national's passport with the entry date, admission status and expiration date listed on the admission stamp and enter all their data into the electronic system. The individuals will be able to access their electronic Form I-94 by visiting www.cbp.gov/I94 and print out their I-94s.
As evidence of lawful admission submitted with a benefit request, USCIS will accept the electronic Form I-94 in paper format obtained from CBP’s website as equivalent to the paper versions of Form I-94. In lieu of submitting the electronic Form I-94 in paper format, USCIS will also accept photocopies of the passport pages that contain the individual’s biographical information, visa and admission stamp.
We'll have to wait and see how smooth this process will actually be...
