I 94 electronic form is your arrival and departure record within the border of the United States. While on a flight to the United States, the flight attendant distributes a form stating the date, flight and the port of entry you are heading to in the US. During your Arrival to the US, this form is handed to immigration. The US homeland security keeps it and encode it in their database. The purpose of I94 is to keep a record of each person travelling in and out of the United States’ border.
What is the use of i94?
I 94 electronic form is required for data recording for all travelers arriving in the United States. I94 is needed during the submission of your i485 package Application to Register Permanent Residence. It is required while applying for a driver’s license and while applying for US citizenship. You will be asked for an updated I-94 when you apply for a State Id card. It is also a main requirement when you apply for ssn (social security number) and driver’s license. They use it to track a foreigner’s identity and arrival date in the US.
Where can you get your updated i94?
A non-immigrant can now get a copy of his/her I94 online at the Department of Homeland Security website https://i94.cbp.dhs.gov/I94/request.html. From that link, you have to click yes and fill out your name, birthdate, passport number and country of issuance. And then a form with your date of arrival in the United States will appear and another form of your travel history within the border.
These record will stay in their database for the period of 5 years while you a Non immigrant is processing your application of citizenship. The I-94 has an expiration date so you will have to return to the same website to request for another one when it is needed.
