A passport entry stamp is an inked impression CBP makes in the foreign national’s passport at the port of entry upon the foreign national’s admission to the U.S. The stamp contains the location of entry point, the date of entry, the class of entry (B-2, H-1B, F-1, etc.), and the duration the foreign national is permitted to stay. In that regard, the passport entry stamp was a useful reference reflecting the tracking of a foreign national’s travel history and immigration status. The same information contained on the passport entry stamp is also reflected on a foreign national’s official admission record, the Form I-94. However, there are often discrepancies between the stamp in the passport and the Form I-94. The Form I-94 is not issued to the foreign national upon entrance, but is instead maintained and available online: https://i94.cbp.dhs.gov/I94/#/home
CBP is eliminating the passport entry stamp to streamline the entry process. Foreign nationals will now only have the Form I-94 to reference as proof of their lawful immigration status.
It is advisable to access and review the Form I-94 soon after entry to the United States, so that needed corrections can be actioned in a timely manner.
