A Non-Resident Indian (NRI) is a citizen of India who holds an Indian passport and has temporarily emigrated to another country for six months or more for employment, residence, education or any other purpose. A Person of Indian Origin (PIO) is a person of Indian origin or ancestry but who is not a citizen of India and is the citizen of another country. A PIO might have been a citizen of India and subsequently taken the citizenship of another country, or have ancestors born in India or other states.
Other terms with vaguely the same meaning are overseas Indian and expatriate Indian. In common usage, this often includes Indian-born individuals (and also people of other nations with Indian ancestry) who have taken the citizenship of other countries. According to the Ministry of Overseas Indian Affairs, India has the second-largest diaspora in the world after overseas Chinese. The overseas Indian community, estimated to number over 25 million, is spread across every major region in the world.
