Since its independence in 1947, India has accepted various groups of refugees from neighbouring countries, including partition refugees from former British Indian territories that now constitute Pakistan and Bangladesh, Tibetan refugees that arrived in 1959, Chakma refugees from present day Bangladesh in early 1960s, other Bangladeshi refugees in 1965 and 1971, Sri Lankan Tamil refugees from the 1980s and most recently Rohingya refugees from Myanmar. In 1992, India was seen to be hosting 400,000 refugees from eight countries. According to records with the Union Ministry of Home Affairs, as on January 1,2021, there were 58,843 Sri Lankan refugees staying in 108 refugee camps in Tamil Nadu and 54 in Odisha and 72,312 Tibetan refugees have been living in India.

The Citizenship (Amendment) Act, 2019 (CAA) was passed by the Parliament of India on 11 December 2019. It amended the Citizenship Act, 1955 by providing an accelerated pathway to Indian citizenship for persecuted religious minorities from Afghanistan, Bangladesh and Pakistan who arrived in India by 2014. The eligible minorities were stated as Hindus, Sikhs, Buddhists, Jains, Parsis or Christians. The law does not grant such eligibility to Muslims from these countries. The act was the first time that religion had been overtly used as a criterion for citizenship under Indian law, and it attracted global criticism.
