Connection time calculator, immigration and security, and how to move between terminals at OAK.
At Oakland airport, as at every airport in the United States, passengers arriving on an international flight must clear immigration (CBP) and customs, collect their checked bags and re-check them, and go through TSA security again before their connecting flight, even when both flights are on the same ticket.
The airport has 2 terminals or concourses (Terminal 1, Terminal 2 (Southwest)). All of them are connected after security, so you do not need to clear security again to change.
