India and International Migration: Trends, Diaspora, and Policy Responses

India possesses the largest diaspora population in the world, with over 32 million Non-Resident Indians (NRIs) and Persons of Indian Origin (PIOs) residing across the globe. The evolution of international migration from India spans colonial indenture, post-independence skilled emigration, and contractual labor flows to the Gulf, shaping global labor markets, remittance flows, and foreign policy.

Waves of Indian Migration

Indentured Labour System (1834–1920)

Following the abolition of slavery across the British Empire in 1833, colonial authorities recruited Indian indentured laborers under the “Girmitiya” system.

• Over 1.5 million Indian laborers were transported to plantation economies including Mauritius, Fiji, Guyana, Trinidad and Tobago, Suriname, and Réunion Island.
• Migration originated mainly from the Bhojpur region of Uttar Pradesh and Bihar, as well as parts of Tamil Nadu and Andhra Pradesh.
• The recruitment ended officially in 1920 following sustained anti-indenture campaigns led by Indian nationalists.

Post-Independence Knowledge Emigration

Beginning in the 1960s, highly educated Indian professionals migrated toward the United States, the United Kingdom, Canada, and Australia.

• Driven by changes in destination immigration laws, such as the US Immigration and Nationality Act of 1965, which abolished national origin quotas.
• Dominated by doctors, engineers, scientists, and software professionals from premier Indian academic institutions.
• This corridor established the foundation for Indian leadership in global Silicon Valley enterprises, academia, and healthcare networks.

Gulf Migration Boom (Post-1973)

The 1973 global oil shock sparked extensive construction and infrastructure development across the Gulf Cooperation Council (GCC) countries.

• Led to temporary circular migration of semi-skilled and low-skilled workers to Saudi Arabia, the United Arab Emirates, Kuwait, Oman, Qatar, and Bahrain.
• Governed under the restrictive Kafala (sponsorship) system, tying a worker’s legal residency and employment status directly to an individual employer.
• GCC nations host over 8.5 million Indian nationals, constituting the largest regional concentration of Indian workers abroad.

Diaspora Categories and Legal Distinctions

Non-Resident Indian (NRI)

An Indian citizen holding an Indian passport who resides outside India for employment, business, or education. Under Section 6 of the Income Tax Act, 1961, an individual is classified as an NRI if they reside in India for less than 182 days during a financial year.

Overseas Citizen of India (OCI)

Introduced through the Citizenship (Amendment) Act, 2005, following the recommendations of the L. M. Singhvi High-Level Committee.

• Eligibility: Granted to foreign nationals of Indian origin whose ancestors were citizens of India on or after January 26, 1950, or were eligible to become citizens.
• Exclusions: Citizens of Pakistan, Bangladesh, or other notified nations are ineligible.
• Privileges: Multipurpose, multiple-entry, lifelong visa for visiting India; parity with NRIs in economic, financial, and educational fields (excluding agricultural property acquisition).
• Limitations: No voting rights, no eligibility for constitutional or public offices, and no right to hold government employment.

Merger of PIO and OCI Cards

The Government of India merged the Person of Indian Origin (PIO) card scheme with the Overseas Citizen of India (OCI) card scheme through the Citizenship (Amendment) Act, 2015, establishing a single OCI category.
