6 Million Viet Kieu: How the Boat People's Descendants Became Vietnam's Hidden Economic Engine

Walk into a pho restaurant in Orange County, California, and you might hear the owner greeting customers in Vietnamese while a South Vietnamese flag hangs on the wall. This is "Little Saigon," the largest Vietnamese community outside of Vietnam — and the spiritual capital of the overseas Vietnamese world.

Viet Kieu is the Vietnamese term for the diaspora — the millions of Vietnamese-origin people scattered across the globe. They carry a complicated history, wield enormous economic influence, and maintain a delicate relationship with their homeland.

6 million people across 130 countries

According to Vietnam's Ministry of Foreign Affairs, about 6 million Viet Kieu live in 130 countries and territories. More than 80 percent reside in developed nations.

The United States is home to the largest concentration — roughly 2.4 million, mainly in California, Texas, and Virginia. Vietnamese Americans are the fourth-largest Asian American group, after Chinese, Indian, and Filipino Americans.

France has about 350,000, Australia 330,000, and Canada 240,000. In Asia, Japan has nearly 500,000, mostly workers and students. Cambodia has close to one million — a community dating back to the 17th century.

The boat people

The mass formation of the Viet Kieu diaspora began in 1975.

On April 30 of that year, the Vietnam War ended and the country was reunified. The new government launched purges of dissidents, former South Vietnamese officials, and military officers. Tens of thousands were sent to "re-education camps." Ethnic Chinese Vietnamese had their assets seized. South Vietnamese currency became worthless overnight.

Fear drove people to flee. They piled onto crude fishing boats, risking pirates, storms, and starvation, drifting toward Hong Kong, Malaysia, Thailand, and Indonesia. These were the "Vietnamese boat people" — one of the largest seaborne refugee exoduses since World War II.

Between 1975 and 1995, nearly 800,000 boat people reached other countries. But the UN refugee agency estimates 200,000 to 400,000 died at sea.

Hong Kong served as a "port of first asylum," receiving over 230,000 Vietnamese refugees across two decades. In 1988, Hong Kong introduced a screening policy, broadcasting announcements in Vietnamese over the radio. The opening phrase — "Bat dau tu nay" (from now on) — became a piece of collective Hong Kong memory, phonetically rendered in Cantonese as "bak lau dong la."

Little Saigon: a city built by exiles

Many boat people eventually settled in places that became "Little Saigons."

The most famous is in Orange County, California, spanning Westminster and Garden Grove. After the fall of Saigon in 1975, refugees were drawn by Southern California's warm weather and affordable housing. They started putting down roots and opening shops. In 1979, there were 30 Vietnamese businesses. By 1981, there were hundreds.

In 1988, Westminster officially designated the Bolsa Avenue corridor as the "Little Saigon Tourist Commercial District." Today it houses hundreds of restaurants, supermarkets, jewelry stores, and clinics — the largest Vietnamese enclave outside Southeast Asia, often called the "Viet Kieu cultural capital."

In 1992, Tony Lam became the first Vietnamese refugee elected to public office in the United States, winning a seat on the Westminster City Council. In 2004, Van Tran became the first Vietnamese American elected to a state legislature.

Remittances: USD 16 billion a year

The most direct economic contribution the Viet Kieu make to Vietnam is through remittances.

In 2024, Vietnam received about USD 16 billion in remittances, matching 2023 and holding at a historic high. Over USD 9.5 billion flowed into Ho Chi Minh City alone, accounting for 60 percent of the national total. Since tracking began in 1993, cumulative remittances have exceeded USD 206 billion — roughly equal to the total amount of foreign direct investment actually disbursed over the same period.

Asia and the Americas account for 82 percent of remittance sources. Asia contributes about 54 percent, mainly from Vietnamese workers in Japan, South Korea, and Taiwan. The Americas represent the traditional Viet Kieu heartland.

Where does the money go? Most of it covers family living expenses, children's education, and real estate purchases. Some goes into small business ventures. Remittances are a vital income source for many Vietnamese families and a key pillar of foreign exchange stability.

Viet Kieu investment: 385 FDI projects

Beyond remittances, Viet Kieu also invest directly in Vietnam.

As of the end of 2022, Viet Kieu from 35 countries had invested in 385 FDI projects in Vietnam, with total registered capital of USD 1.72 billion across 42 provinces and cities. Manufacturing accounts for 45 percent, followed by services and energy. Hanoi attracts the most Viet Kieu investment, followed by Long An, Binh Thuan, Hai Phong, and Dong Nai.

Many Viet Kieu entrepreneurs say that investing back home often means navigating red tape and opaque regulations. They've called for the government to set up dedicated service desks to help.

Five-year visa exemptions and a new dual nationality law

The Vietnamese government has been actively courting the Viet Kieu in recent years.

Those who gave up Vietnamese citizenship can apply for a five-year multiple-entry visa exemption, with stays of up to 180 days per visit, for a fee of just USD 10 to 20. This makes it far easier to visit family and handle business.

An even bigger shift came with the amended Nationality Law, effective July 2025. Vietnam had long restricted dual nationality. The new law significantly loosens the rules, making it easier for overseas Vietnamese and their children to obtain or restore Vietnamese citizenship while keeping their foreign passports.

Vietnam's Minister of Justice said the goal is to attract overseas talent and capital, especially Viet Kieu with expertise in AI and semiconductors. The government's calculus is straightforward: 80 percent of the 6 million Viet Kieu live in developed countries. Their money, skills, and networks are a potential resource for Vietnam's industrial upgrade.

Fifty years later

2025 marks the 50th anniversary of the end of the Vietnam War.

The refugees who risked their lives to flee are now grandparents. Their children and grandchildren were born and raised in the United States, France, and Australia. Some speak fluent Vietnamese; some know only a few words. Every Lunar New Year, the flower markets in Little Saigon are still packed, but the young people running the stalls are more likely to chat in English.

For the Vietnamese government, these 6 million people represent a resource to be won over. For the Viet Kieu themselves, the relationship with their homeland is far more complicated. Some go back to invest. Some refuse to set foot on Vietnamese soil. Some are actively restoring their citizenship. Others consider themselves citizens of another country entirely.

Regardless, this global diaspora has deeply shaped Vietnam's economy and culture. The USD 16 billion in annual remittances, the pho shops of Little Saigon, and the achievements of a new generation of Vietnamese Americans and Vietnamese Europeans and Vietnamese Australians — all are traces of a story of dispersal that began half a century ago.
