"Sikhs are often harassed and pressured to reject religious practices and beliefs that are distinct to Sikhism, such as dress, unshorn hair, and the carrying of religious items, including the kirpan," the US Commission on International Religious Freedom (USCIRF) in its report for 2015.
"India's Sikh community has long pursued a change to Article 25 of India's constitution which states, Hindus shall be construed as including a reference to persons professing the Sikh, Jain or Buddhist religion, and the reference to Hindu religious institutions shall be construed accordingly," the report said.
Calling panel's report a "landmark" for recognising the labeling of "Sikhs" as "Hindus" in Indian Constitution, attorney Gurpatwant Singh Pannun, legal advisor to Sikh For Justice (SFJ) said "recognition of Sikh with separate identity issue by US will shore up the support for Sikh community's demand for right to self-determination".
"Now we will approach the world community seeking their support for referendum in the state of Punjab," Pannun added.
