Potential beneficiaries from Ukraine will need to submit biographic and biometric information to the U.S. government for the security vetting process. Individuals will be vetted through interagency intelligence, law enforcement, and counterterrorism background checks. Anyone who does not pass security checks conducted overseas will not be authorized to travel to the United States. Upon their arrival at a port of entry, each person will be inspected by U.S. Customs and Border Protection (CBP) to undergo additional screening and vetting, including biometric screening. Anyone who is found to pose a national security or public safety threat will be referred to U.S. Immigration and Customs Enforcement (ICE). Applicants will also need to confirm prior vaccination against measles, polio, and COVID-19. If they are not previously vaccinated, individuals will need to receive a first dose of required vaccines prior to obtaining authorization to travel to the U.S. In addition, children who are at least 2 years old will need to complete a medical screening for tuberculosis, including an Interferon-Gamma Release Assays (IGRA) test, within two weeks of arrival to the U.S. Other travel requirements are outlined by the Centers for Disease Control and Prevention (CDC), including pre-departure testing for COVID-19.
