A non-resident Indian (NRI) is an Indian citizen who has migrated to another country. Other terms with the same meaning are (somewhat self-deprecating in context) desis, overseas Indian and expatriate Indian. For tax and other official purpose the government of India considers any Indian national away from India for more than 183 days in a year an NRI. In common usage, this often includes India born individuals (and also people of other nations with Indian blood) who live in other countries.
