There are various laws which require DHS to create an integrated, automated biometric entry and exit system that records the arrival and departure of foreign nationals; biometrically compares the identities of foreign nationals; and authenticates travel documents presented by such individuals through the comparison of biometric identifiers. US-VISIT is designed to meet these goals. However, travelers should be aware that as US-VISIT allows DHS to track entries to and departures from the U.S., as well as access any arrest or criminal records, it is important that the information DHS (USCIS, the Consulates, CBP) has in its various databases is accurate. Inaccurate information in the database will yield an erroneous “hit” in US-VISIT, causing the traveler delay and frustration. Now more than ever it is imperative that travelers review their I-94 cards for accuracy upon each entry to the U.S., and ensure that all I-94 cards are turned in upon their departure from the U.S. This will help avoid an erroneous database entry of an overstay or other immigration violation.
