The I-94 card is currently required as proof of status for a number of different purposes with a number of different agencies: obtaining a Social Security Number from the Social Security Administration; obtaining a Driver’s License from DMV; filing for a change or extension of status with the U.S. Citizenship and Immigration Services (USCIS); and as proof of work authorization on an I-9 employment verification document. The I-94 document will still be required for these purposes.
