I-94 UPDATE: Department of Homeland Security is no longer issuing paper I-94 cards at entry. All non-immigrants must print their electronic I-94 cards immediately after entry at https://i94.cbp.dhs.gov/I94/. It is very important to review for errors in spelling, expiration date and visa category. Print a copy for your records. You are solely responsible for tracking your lawful stay and that of your family members while in the United States.
