The immigration officer who is checking a nonimmigrant’s passport to allow the person to enter into the United States used to give a white card to the person. This card should be kept in the person’s passport and stored in a safe place. This card has important information, such as the date a person entered into the United States, the person’s current status, and how long the person is allowed to remain in the United States.
Immigration has changed the process. A person who enters into the United States must go online and print his or her own I-94 for each trip made to the United States.
