The Indian Diaspora: Categories, History and Policy

Prerequisites: The Indian Diaspora — overview

The Hook: Bringing the Students Home

The Core Concept

Who counts as the “diaspora”?

graph TD
    A[Overseas Indians] --> B[NRIs: Indian citizens living abroad]
    A --> C[Persons of Indian Origin: foreign citizens with Indian roots]
    C --> D[OCI cardholders: registered under Section 7A of the Citizenship Act]
    C --> E[PIO cards: merged into OCI in 2015]

OCI — what it gives and what it does not

A person is not eligible for OCI if they, or either of their parents or grandparents, have ever been a citizen of Pakistan or Bangladesh (or another country the Government notifies). Foreign military personnel are also excluded.

Why not dual citizenship? Article 9 of the Constitution says a person who voluntarily acquires the citizenship of a foreign State ceases to be an Indian citizen. OCI was designed as a way to keep ties without dual citizenship.

The waves of migration

Indenture anchors:

• The first indentured labourers arrived in Mauritius on 2 November 1834. The Aapravasi Ghat in Port Louis, where they landed, is a UNESCO World Heritage Site (2006).
• Other first arrivals: British Guiana (1838), Trinidad (1845), Natal (1860), Suriname (1873), Fiji (1879).
• Gandhi’s campaign in South Africa and the nationalist movement opposed indenture; recruitment was stopped in 1917 and the system formally ended in 1920. The word Girmitiya comes from “agreement” (girmit).
• In 1972, Idi Amin expelled people of Asian (largely Indian) origin from Uganda — a reminder of how host-country politics can uproot a diaspora.

How the Indian state engages the diaspora

ECR (Emigration Check Required): passport holders in the ECR category (broadly, those who have not passed Class 10) need emigration clearance to work in 18 notified countries, mostly in the Gulf and West Asia, plus some in South-East Asia.

Evacuation operations

Why the diaspora matters

• Remittances: India is the world’s largest recipient. It was the first country to receive more than **US$100 billion** in a year — over US$111 billion in 2022 (IOM, World Migration Report 2024). Remittances help finance the trade deficit and sustain household incomes.
• Investment and skills: diaspora entrepreneurs and professionals link India to global technology, capital and research networks (“brain circulation” rather than “brain drain”).
• Soft power and advocacy: diaspora groups helped build support in the US Congress for the India–US civil nuclear agreement (2008); leaders of Indian origin hold high office in several countries.
• Cultural bridges: festivals, yoga, cuisine and cinema carry Indian culture abroad.

Challenges

• Gulf workers: wage theft, contract substitution, confiscation of passports, and the kafala sponsorship system; localisation policies (Saudi Arabia’s Nitaqat).
• Immigration rules in the US, UK, Canada and Australia; visa backlogs; student vulnerability to fraudulent agents.
• Irregular migration and trafficking routes.
• Racial hostility and hate crimes in some countries.
• Extremism: small extremist and separatist groups in some host countries — a factor in India–Canada tensions since September 2023.
• Data gaps: India has no complete registry of its emigrants.

Memory Anchors

NRI, PIO, OCI: “National, Past, Overseas pass” → NRI is still a National (citizen); PIO has Indian Past (ancestry); OCI is a lifelong Overseas pass (visa), not citizenship.

Indenture order — “My Grandfather Took New Ships Far” → Mauritius 1834 · British Guiana 1838 · Trinidad 1845 · Natal 1860 · Suriname 1873 · Fiji 1879.

PBD date: 9 January = Gandhi’s return from South Africa (1915) — “the greatest pravasi came home”.

One-line Mains hook: “The diaspora is India’s bridge to the world — and every bridge needs maintenance from both ends.”

For Prelims

For Mains

• Dimensions: economic (remittances, FDI, skills), strategic (lobbying, soft power), social (welfare of workers, families left behind), political (diaspora politics, extremism), legal (citizenship, dual citizenship debate), humanitarian (evacuations).
• Keywords: brain circulation, soft power, diaspora diplomacy, safe and legal migration, migrant welfare, return migration, skilling for global mobility.
• Value-addition: L.M. Singhvi Committee; IOM’s remittance data; Operation Ganga and Vande Bharat as examples of the “duty of care”; migration and mobility partnership agreements with countries such as France and Germany to open legal pathways.

Common Traps

In the News

• February–March 2022 — Operation Ganga, Ukraine.
• April 2023 — Operation Kaveri, Sudan; October 2023 — Operation Ajay, Israel.
• January 2025 — the 18th Pravasi Bharatiya Divas convention held in Bhubaneswar, Odisha.
• June 2025 — Operation Sindhu evacuates Indian nationals from Iran and Israel.
