I-94 Arrival/Departure Forms

Form I-94 is the DHS arrival/departure record. The I-94 is an extremely important piece of your travel record and status while in the United States. You should have a copy of the actual Form I-94Arrival/Departure Record which provides evidence of your legal admission to the U.S. 

Each time you enter the U.S., you will be issued a new I-94. Immediately after each entry, you should go to the I-94 website to pull up the new I-94 PDF and PRINT a copy for your records and as evidence of legal entry.  
You are required to upload your I-94 record in iStart as proof of your arrival into the United States during the Mandatory Document Check-In process. 
If you have been granted F-1 or J-1 status through a Change of Status process and do not have a visa stamp in your passport, you will receive an I-797 Approval Notice instead of an I-94 as proof of your status in the U.S.
