Cab driver Curtis Seymour got the call at 3:30 a.m. to pick up a passenger at the Greyhound bus station in Plattsburgh, New York, about 25 miles (40 km) south of the Canadian border.
An older Haitian woman wearing a purple and yellow headwrap, mauve lipstick and big gold earrings descended from the bus with two handbags, a backpack and a suitcase. Seymour placed her luggage in the car, and asked where she was headed.
One man from Somalia left behind his U.S. employment authorisation card, which won't expire until September 2017. It read: "NOT VALID FOR REENTRY TO THE U.S."
Others abandon belongings too heavy to carry, which Seymour donates to drop-off centres around town.
Passengers who do not speak English, Seymour said, sometimes use different techniques for communication.
"One woman with her child spoke no English whatsoever and just drew me a picture of a fence."
