Newark Liberty International has 3 terminals, all 3 terminals service inbound international flights. Are all inbound international passengers routed to the same customs hall (service area) or is there more than one hall?
Only Terminals B and C have immigration facilities; they are separate from each other. Arrivals in Terminal B clear immigration in Terminal B, and arrivals in Terminal C clear immigration in Terminal C.
There is no immigration facility in Terminal A. Only international flights which went through US preclearance (and domestic flights) arrive at this terminal.
