When you cross the border into the United States, Customs and Border Protection (CBP) uses the I-94 system to record all entries and exits from the United States. As for air and sea border crossings, the system works independently and does not require filling in anything. But if you are crossing the border by land, for example from Mexico or Canada, then you need to fill out a form. It is possible to fill it out online or in person.

If you are arriving by land, fill out the I-94 in person before your arrival, but there is nothing to do and fill out if you are arriving by plane or ship.
