The I-94 is proof of your legal entry in the United States. It also documents the period of stay that has been granted by the US authorities. When the United States (US) grants permission for someone to legally enter the country, an I-94 is issued. It is no longer a card issued at the airport or filled out on flights. This document is retrieved by visiting the Homeland Security Website at www.cbp.gov. Please note that customs officials can make mistakes when entering this document. It is therefore crucial to look at what is stamped in your passport before leaving the arrival section at the airport. Ensure the correct year is stamped in your passport. Make sure the correct work visa designation is assigned. Make sure the date written in by the officer is also correct and covers the contract period of the work visa.
