What this page cannot show

  • An encounter is an event. The same person may be encountered more than once, so these are not counts of people.
  • The area of responsibility is the sector or field office that recorded the encounter. It is not where a person entered, and not where they intended to go.
  • CBP revises earlier months when it republishes the file, so a figure is only as current as the snapshot it was drawn from.
