The Sikh man, a physician scientist, said in a statement that he and his mother were attacked in a Queens neighbourhood on the night of August 7.
He said that in accordance with Sikh religious beliefs, both he and his mother wear turbans and maintain uncut hair.
They were confronted by about 10 teenagers who called them "Osama bin Laden and told us to go back to your country."
The Sikh man told them to stop, but the teenagers surrounded him and punched him in the face and neck. They also tried to throw a bottle at the Sikh man and then fled.

The man, who chose to remain anonymous, said he tried to pursue them but could not as he was in a lot of pain. He then called the police and was treated at a hospital.
"I want the New York Police Department to investigate this attack as a hate crime and arrest the people who attacked me before they hurt someone else. I want witnesses to come forward and contact the police immediately," the man said, adding that his mother was visiting him from India.
Rights group Sikh Coalition called on Mayor Bill de Blasio to work with the community to end violence and discrimination against Sikhs.
"Enough is enough," it said, urging witnesses to call federal authorities giving any information they may have on the 10 teenagers. The group included a white male, three females while the rest were black men.
"We're tired of being targeted again and again by bigots, but Sikh Americans are not afraid and are not going to let a small group of narrow-minded individuals get us down," Rajdeep Singh, Director of Law and Policy at the Sikh Coalition, said.
Sikh Coalition said it has requested the intervention of NYPD's Hate Crime Task Force.
The attack occurred just days after 29-year-old Sandeep Singh was brutally injured when he was hit and dragged nearly 30 feet on a public street in Queens by a pick-up truck following an argument with the truck's driver who called him a "terrorist" who should "go back to your country."
