Inspection at the Airport or Border Post by U.S. Customs and Border Protection (CBP)
When you arrive at the Los Angeles International Airport (LAX) or other U.S. port of entry, a CBP officer will review your documents and grant entry to the United States by taking your photograph, fingerprints, and stamping your passport. See CBP Inspection Process for details.
Canadian citizens arriving to work or study at Caltech/JPL should avoid using airport self-service kiosks to process entry to the United States. The kiosks are for visitors (B1/B2) only.
Review your passport stamp immediately, while you are still with the CBP officer. The passport should be stamped with your arrival date and your immigration status. If you are an F-1, F-2, J-1 or J-2, the CBP officer should write "D/S" on the stamp. If you are entering the United States in any other status, the handwritten date should match the expected end date of your visit.
Collect your luggage after completing the initial CBP inspection, then proceed through the second inspection where you will make a customs declaration. For more information, visit CBP for International Visitors.
