Pakistani immigrants from the Swat Valley, where the Taliban have been battling Pakistani security forces since 2007, say some of their families are being singled out for threats, kidnapping and even murder by Taliban forces, who view them as potential American collaborators and lucrative sources of ransom. Some immigrants also say they, too, have been threatened in the United States by the Taliban or its sympathizers, and some immigrants say they have been attacked or kidnapped when they have returned home.

The threats have brought an added dimension of suffering for the immigrants, who say fresh reports of hardship arrive here every day, sometimes several times a day, and spread quickly among the several thousand Swati immigrants in the New York region: families driven from their villages, houses being destroyed, relatives disappearing. The fate of the valley dominates conversation among the exiles.

“It’s 24/7,” said Zakrya Khan, 30, the owner of two gyro restaurants in New York whose staff of 15 is almost entirely Swati. “This is their only concern now.”

Though every community of exiles from a conflict-ridden country suffers when relatives who remain behind are caught in the fight, the immigrants from Swat also bear the burden of believing that their presence in America is endangering their relatives back home, where the Taliban have imposed their authority over vast swaths of the region, about 100 miles northwest of Islamabad.

More than that, Swati immigrants say they have been left with the sense that the more they try to help their families back home, the more harm they may do, an excruciating dilemma that has filled many with a combination of helplessness, fear, sadness and guilt.
