Are you a frequent flyer to the USA? Then consider enrolling to global entry.

If you travel to the US more than 2 or 3 times a year then consider US Global Entry. Because of my frequent visits to the USA I was invited to in enroll to the global entry program. The fee is nominal if you are a frequent flyer to the United States of America. It means that you cut passport checking upon arrival into the US and believe me when I tell you it can shave off so much time dependent on the queues at the airport that you were arriving. You just head straight to the Global Entry machines, it scans your passport takes a few personal details from you, and then you're good to go and you can pick up your luggage. It'll save so much time.
