"We would like to respectfully express our strong support for adding three new categories to the FBI's Hate Crime Statistics Act (HCSA) data collection mandate -- anti-Sikh, anti-Hindu and anti-Arab hate crimes. Unfortunately, there is a specific, demonstrated need for hate crime data for each of these three categories," said the letter on circulation.

"We are in favor of such a move in part because many Congressional offices have heard from constituents and leaders in the Sikh, Hindu and Arab-American communities about their ongoing fear of being the victim of a hate crime," it said.

"This fear is a result of demonstrable and specific violent threats and attacks. For example, a man attempted to firebomb a Hindu Temple in New York on New Year's Day, 2012.

In December 2012, a Hindu man whose attacker said she hated Hindus and Muslims was shoved in front of an oncoming subway train, resulting in his death," the letter said.

The Indian American Forum for Political Education (IAFPE) has expressed their willingness to be a part of the campaign and they have also requested the lawmakers, especially members of the India Caucus to sign the letter.

"We would request Department of Justice( DOJ) to ask the Federal Bureau of Investigation (FBI) to begin collecting data on Hate Crime committed against Hindus, Sikhs and other minority communities of Indian origin," said Sampat Shivangi, national president of the Forum.
