I-94 card
As an immigrant, when you arrive in the U.S., an arrival/departure record card is issued and placed in your passport next to your visa. This is called an I-94 card that permits a foreigner to be in the U.S. (as opposed to visa that provides the right to travel in and out of the U.S. in a certain status, eg. H1B visa status). The U.S. immigration official at the U.S. port of entry will review the foreigner’s immigration documents (eg. H1B visa) and stamp the I-94 card with an expiry date consistent with the visa expiry. It should be noted that the immigration official has the power to limit a foreigner’s stay irrespective of the visa expiration. The I-94 card is removed when a foreigner departs the U.S.
