All travelers, both domestic or international, upon their entry to the United States, must go through TSA security screening. Passengers should put their belongings in a bin for X-ray scanning and go for checking under a body scanner.
Norman Y. Mineta San José International Airport has two terminals. Both Terminal A and B hosts arrived passengers who should hold their place in an appropriate queue depending on the status of the state. The citizens of the United States in one line and international travelers in another.
Border Control and Customer Protection
At San Jose International Airport, the principal office of "The Customs and Border Protection" is situated in the south of the International Arrivals area. Border Protection (CBP) service is ready to meet travelers for screening. Passengers can be asked the reasons for their arrival, duration of their stay, place or even address of visit, etc. so remember to answer all the questions honestly with patience. During identification clearance, passengers should present a valid passport, not a US visa, which is not enough to enter the United States.
All travelers arriving at SJC via international flights must clear immigration customs in the "International Arrivals building." Note that flights from US border airports are exceptional.
