Is the I-94 record important?

The I-94 is very important. The online I-94 arrival record is created by U.S. Customs and Border Protection officers and is an important legal document. It shows the individual’s immigration status and the granted period of admission.  F and J visa holders must closely monitor their I-94 Admit Until Date after each international travel. It is the F and J visa holder's responsibility to meet critical deadlines such as their timely departure from the U.S. or submitting a timely application for an Extension of Stay (EOS) with USCIS.
