The term diaspora originates from the Greek word 'diaspeiro', meaning dispersion. It refers to a population that has been dispersed from its traditional homeland to other parts of the world.
The Indian diaspora represents one of the largest and most diverse global communities. Its growth began significantly with the historical movement of indentured laborers.
The 'Girmitiya' arrangement involved the transportation of indentured laborers, primarily from India, to various countries. These included regions in the East Pacific and the Caribbean Islands during the 19th and early 20th centuries.
The Indian government classifies its overseas population into distinct categories to facilitate engagement and policy formulation. These categories are primarily based on residency status and citizenship.
Non-Resident Indians (NRIs) are Indian citizens who reside outside India for employment, business, or any other purpose, indicating an indefinite stay abroad. They retain their Indian citizenship.
A person is considered an NRI if they meet specific residency criteria:
The category of Persons of Indian Origin (PIOs) historically referred to foreign citizens who had an Indian connection. This connection could be through past Indian citizenship, or through their parents or grandparents being born in India.
A spouse of an Indian citizen or a PIO was also eligible under this category. However, certain nationalities were excluded from applying.
Excluded Nationalities for PIO application included citizens of Pakistan, Afghanistan, Bangladesh, China, Iran, Bhutan, Sri Lanka, and Nepal.
It is crucial for UPSC aspirants to note that the PIO card category was abolished in 2015. It was subsequently merged with the Overseas Citizen of India (OCI) category, simplifying the classification system for persons of Indian origin.

Similar to PIO, nationals of Pakistan and Bangladesh are explicitly excluded from OCI card eligibility.
