The Punjabi diaspora consists of the descendants of ethnic Punjabis who emigrated out of the Punjab region in Pakistan and India to the rest of the world. Punjabis are one of the largest ethnic groups in both the Pakistani and Indian diasporas. The Punjabi diaspora numbers around the world has been given between 3 and 5 million, mainly concentrated in Britain, Canada, the United States, Western Europe, Southeast Asia, the Middle East, Australia and New Zealand.

British Indians are citizens of the United Kingdom (UK) whose ancestral roots are from India. Currently, the British Indian population exceeds 2 million people in the UK, making them the single largest visible ethnic minority population in the country. They make up the largest subgroup of British Asians and are one of the largest Indian communities in the Indian diaspora, mainly due to the Indian–British relations (including historical links such as India having been part of the British Empire and still being part of the Commonwealth of Nations). The British Indian community is the sixth largest in the Indian diaspora, behind the Indian communities in the United States, Saudi Arabia, the United Arab Emirates, Malaysia and Nepal. The majority of British Indians are of Punjabi and Gujarati origin with various other smaller communities from different parts of India including Kerala, West Bengal, Bihar and Uttar Pradesh.

The Indian Legion (German: Indische Legion), officially the Free India Legion (German: Legion Freies Indien) or 950th (Indian) Infantry Regiment (German: Infanterie-Regiment 950 (indisches)), was a military unit raised during the Second World War initially as part of the German Army and later the Waffen-SS from August 1944. Intended to serve as a liberation force for British-ruled India, it was made up of Indian prisoners of war and expatriates in Europe. Owing to its origins in the Indian independence movement, it was known also as the "Tiger Legion", and the "Azad Hind Fauj". As part of the Waffen-SS it was known as the Indian Volunteer Legion of the Waffen-SS (German: Indische Freiwilligen Legion der Waffen-SS). The transfer to the Waffen-SS was never fully executed and many members of the division refused to wear the new uniforms and insignia.

Indian independence leader Subhas Chandra Bose initiated the legion's formation, as part of his efforts to win India's independence by waging war against Britain, when he came to Berlin in 1941 seeking German aid. The initial recruits in 1941 were volunteers from the Indian students resident in Germany at the time, and a handful of the Indian prisoners of war who had been captured during the North African campaign. It later drew a larger number of Indian prisoners of war as volunteers.

Overseas Citizenship of India (OCI) is a form of permanent residency available to people of Indian origin which allows them to live and work in India indefinitely. It allows the cardholders a lifetime entry to the country along with benefits such as being able to own real estate and make other investments in the country.

Despite its name, OCI is not recognised as citizenship by the Republic of India or by the vast majority of nations worldwide, and it does not grant the right to vote in Indian elections or hold public office. The Indian government can revoke OCI status in a wide variety of circumstances. In addition, the OCI card is only valid with a valid foreign passport. As of 2022, there are 4 million holders of OCI cards among the Indian diaspora.

Malaysian Indians or Indo-Malaysians are Malaysian citizens of Indian ancestry. Most are descendants of those who migrated from India to British Malaya from the mid-19th to the mid-20th centuries. Most Malaysian Indians are ethnic Tamils; smaller groups include the Malayalees, Telugus and Punjabis. Malaysian Indians form the fifth-largest community of Overseas Indians in the world. In Malaysia, they represent the third-largest group, constituting 7% of the Malaysian population, after the Bumiputera (combined grouping of ethnic Malays and other indigenous groups) and the Chinese. They are usually referred to simply as "Indians" in English, Orang India in Malay, "Yin du ren" in Chinese.

Malaysia's Indian population is notable for its class stratification, with a significant elite and a large low income group within its fold. Malaysian Indians large percentage of professionals per capita by constituting 15.5% of Malaysia's professionals in 1999 has been reduced with substantial population close to 40% is now considered the B40 category. In the 1984 census, up to 38% of the nation's medical professional workforce consisted of Malaysian Indians, but this has been since been reduced. In 1970, the per-capita income of Malaysian Indians was 76% higher than that of the Malay majority. Despite attempts by the Malaysian government to redistribute wealth since the 1970s through institutionalized racial policy, by 2005 Malaysian Indians still earned a 27% higher per capita income than that of the dominant Malay community.

Indian Australians or Indo-Australians are a subgroup of the Indian diaspora residing in Australia. This includes both those who are Australian by birth, and those born in India or elsewhere in the diaspora. Indian Australians are now one of the largest groups of the Indian diaspora, with 783,958 persons declaring Indian ancestry at the 2021 census, representing 3.1% of the Australian population, and 673,352 stating that they were born in India. If all "Indian-related ancestries" are grouped together, that number rises to 970,000, or 3.8% of the country's population. Furthermore, by June 2024, the Australia Bureau of Statistics reported that the Indian-born population had risen to 916,330 individuals, an increase of nearly 150,000 in 3 years.

Having long been restricted from entry under the White Australia policy, the number of Indians in Australia has increased exponentially in the 21st century. Indians now form the fastest-growing community both in terms of absolute numbers and percentages in Australia, and also have the youngest average age (34 years). As of 2016, Indians were the highest-educated migrant group in Australia, with 54.6% of Indians in Australia having a bachelor's or higher degree, more than three times the Australian national average.

Indo–Trinidadians and Tobagonians or Indian Trinidadians and Tobagonians are people from Trinidad and Tobago whose ancestors are of Indian origin that came from India and the wider subcontinent beginning in 1845 during the period of colonization and indentureship.

Indo-Trinidadians and Tobagonians are a subgroup of Indo-Caribbean people, which is a subgroup of the wider Indian diaspora. Generally, most Indo-Trinidadians can trace their ancestry back to North India especially the Bhojpur and Awadh regions of the present day Indian states of Bihar and Uttar Pradesh, two states located in the Gangetic plains of the Ganga and Yamuna rivers. However, some Indo-Trinidadians may trace their ancestry to other parts of South Asia, notably South India, such as the Indian state of Tamil Nadu. Indians first arrived in Trinidad and Tobago as indentured laborers from India through the Indian indenture system from 1845 till 1917, and some Indians and other South Asians, along with their families, later came as entrepreneurs, businesspeople, religious leaders, doctors, engineers, and other professional occupations beginning in the mid-20th century. Some Indo-Caribbean people from many other Caribbean nations, such as Guyana, Grenada, Martinique, and Saint Croix, also immigrated to Trinidad and Tobago.
