CBP Officers working at U.S. ports of entry are also informed electronically of the visa revocation by means of the following databases; Consular Consolidated Database (CCD), Consular Lookout Automated System (CLASS) and through the Treasury Enforcement Communication System (TECS) in case the traveler arrives seeking admission into the United States.

When a international citizen visits the U.S. as a tourist, a medical patient, a scholar, or for enterprise functions, they often must present only a sound nationwide passport, a photograph ID card or beginning certificate, and sometimes an entry visa.
