 There has been concern raised at the lack of inclusion of several Non-Muslim countries around India in the Citizenship Bill, such as Sri Lanka, over whom Shiv Sena and several religious figures have raised concern over the citizenship status of Tamil-speaking Hindus who were allowed to legally settle in the Indian state of Tamil Nadu due to previous discrimination on the island, and Nepal and Bhutan, the latter of which is accused of discriminating against Hindus through a Buddhist-only society.Tibetans refugees from China are also excluded from the bill despite being an ongoing concern.Those without valid Indian citizenship or visas are classified as illegal immigrants.
