Even if an ESTA has been approved initially, it may later be ESTA revocation if new information is discovered.
U.S. Customs and Border Protection (CBP) continuously reviews travelers’ eligibility to enter the United States under the Visa Waiver Program (VWP).
During this process, various security screenings and immigration checks are conducted, and multiple immigration and law enforcement databases may be used.
If new information is discovered during this review that may affect a traveler’s eligibility to enter the United States, the approved ESTA may result in ESTA revocation.
