America sold the world a dream – and kept millions chasing it

For decades, America sold the world a simple promise: come here, work hard, and you could build a better life. Millions believed it.

In 1970, just 9.6 million foreign-born people lived in the United States, accounting for 4.7% of the population. By 2024, that number had risen to about 50 million, according to the US Census Bureau. In little more than half a century, America’s foreign-born population had increased more than fivefold.

That growth was not the result of a single visa programme or one great migration wave. America spent decades building an ecosystem around migration: family reunification, universities, jobs, permanent residence and citizenship. As immigrant communities grew, they also made it easier for the next generation to follow.

“America’s pull has never been one immigration rule,” said Poorvi Chothani, Managing Partner at LawQuest. “It is the combination of a huge and innovative labour market, world-leading universities, a durable and reliable rule-of-law system, and—crucially—an immigration framework that offers some migrants a credible route from temporary status to permanent residence and eventually citizenship.”

Rajiv Khanna, Managing Attorney at Immigration.com, puts the appeal more simply: “What drew people here was permission to try.”

That may be the central reason America became not just a country people migrated to, but a country millions imagined migrating to.

The law that changed the guest list

The modern story starts in 1965. Until then, US immigration policy relied heavily on national-origin quotas that shaped where immigrants could come from. The Immigration and Nationality Act amendments of 1965 dismantled that system and placed greater emphasis on family relationships and skills.

“It is the foundation,” Khanna said. “Nearly everything about the modern immigrant population traces back to it.”

The consequences unfolded over decades. Immigration increasingly came from Asia and Latin America rather than primarily from Europe. Later reforms widened the system further. The Immigration Act of 1990 expanded employment-based immigration and added other routes into the country.

Family migration was especially important because it allowed migration to build on itself.

“Family-based immigration made family unity a durable part of the system, and it created a genuine network effect,” Chothani said. Beyond the legal ability to petition for qualifying relatives, she added, family and community networks helped newcomers find housing, jobs, schools and professional contacts.

Khanna described the same process more bluntly: “The statute builds compounding into itself.”

One migrant, then another

That compounding effect became one of America’s biggest advantages.

The first migrant in a family has to figure out where to live, how to find work, which schools to choose and how the immigration system works. The next migrant may already have someone to call.

As communities expanded across New York, California, Texas, New Jersey and elsewhere, migrants increasingly arrived in places where earlier arrivals had already built businesses, professional networks and community institutions.

“The cousin already here tells you which university actually places its graduates, which employers file H-1B petitions, which suburb has the schools, which lawyer to retain,” Khanna said. “That knowledge is worth more than any brochure a government produces.”

That changed the economics of migration. The decision was no longer just about wages. It was also about whether relatives lived there, whether employers recruited people with similar qualifications and whether a community already existed.

Each migrant reduced some of the cost and uncertainty faced by the next.

Then the 'Dream' started compounding

Other wealthy countries built successful immigration systems too. Canada and Australia recruited skilled migrants, Germany became a major immigrant destination and Britain attracted international workers and students.

But America accumulated something competitors could not quickly reproduce: scale.

According to the United Nations’ International Migrant Stock 2024, the United States hosted 52.4 million international migrants in 2024, compared with 16.8 million in Germany, 8.8 million in Canada and 8.1 million in Australia.

America is not the country with the highest migrant share of its population. Australia and Canada, among others, have higher shares. Its advantage is the absolute size of the network.

“America’s advantage is cumulative,” Chothani said. “Decades of alumni networks, family ties, diaspora institutions, capital markets and globally recognised employers reinforce one another.”

For Indians, the dream got a campus address

India offers a particularly clear example of how that system works.

US colleges and universities hosted 363,019 students from India in the 2024-25 academic year, according to the Open Doors 2025 report, an annual US government-funded survey of international student mobility produced by the Institute of International Education (IIE). That made India the largest source of international students in the US. Overall, American institutions hosted about 1.18 million international students that year.

For an Indian student, education also reduced the size of the initial migration decision. Moving permanently is a major commitment; going for a master’s degree is a more defined first step.

From there, students could build professional networks, enter the labour market and, in some cases, move from practical training to employment visas and eventually permanent residence.

“US universities are one of America’s most effective talent pipelines,” Chothani said, while stressing that the sequence from student to worker to permanent resident is not automatic and each stage carries separate legal requirements.

Khanna goes further. “They are not part of the corridor. They are the corridor,” he said of the F-1, H-1B and employment-based green-card routes for Indians.

USCIS data support the scale of that link: 71% of approved H-1B petitions in fiscal 2024 were for beneficiaries born in India.

America’s accidental founder factory

For many skilled migrants, America’s immigration system was never elegant.

It was often slow, uncertain and difficult to navigate. Yet people continued to enter it because the economic upside remained large.

Khanna argues that the H-1B programme became more than a labour visa. “The H-1B was never a founder’s visa. It functioned as a founder’s apprenticeship.”

That argument is backed by data on immigrant entrepreneurship. A June 2026 study by the National Foundation for American Policy found that immigrants founded or co-founded 455 of America’s 775 privately held billion-dollar companies, or 59% of the total. Indian-born founders were behind 96 of them, more than any other country of origin.

Khanna’s point is that many such founders first entered the country as students or skilled workers rather than as entrepreneurs.

The system, in other words, sometimes produced outcomes it had not explicitly been designed to create.

The prize wasn’t just a paycheque

America’s advantage was also about what happened at the end of the immigration journey.

A temporary labour system can offer someone a better salary. America could offer the possibility of permanent residence and eventually citizenship.

“A credible route from permanent residence to citizenship gives migrants a reason to invest deeply in the country: to build careers, businesses, families and civic ties,” Chothani said.

Khanna calls citizenship “probably the largest structural advantage this country has.”

For many migrants, particularly those with children, that changed the calculation. The promise was not simply a job in another country. It was the possibility of becoming part of that country.

That helps explain why Indians have continued choosing the US despite some of the longest employment-based green-card waits.

“The fact that people still come reflects the strength of the opportunity, not an endorsement of the delay,” Chothani said.

Khanna makes a similar distinction: people were not simply enduring the wait for a green card. “They endured it for excellence and opportunity.”

America found millions of salespeople

Immigration law explains how people could reach America. It cannot fully explain why so many wanted to.

American films, television, music, universities and companies gave the country enormous visibility abroad. People who had never visited the US still knew New York and California, Harvard and Stanford, Hollywood and Silicon Valley.

But eventually immigrants themselves became a more credible distribution network for the American Dream.

A cousin in California could explain how to apply to university. A relative in New Jersey could provide somewhere to stay. An engineer in Texas could tell someone which companies were hiring.

The dream increasingly travelled through families, alumni networks and professional circles rather than only through American popular culture.

This is where Chothani’s description of the ecosystem becomes most useful: policy created the legal doors, but jobs, universities and communities supplied “the reason and the capacity to walk through those doors.”

The dream became bigger than the policy

America’s immigration advantage was never that the system was simple.

It wasn’t.

The paperwork could be slow, visa numbers were limited and green-card waits could last years. Yet the opportunity at the end of that process remained strong enough that millions were willing to try.

That is also why current immigration slowdowns do not erase the larger story. America spent more than half a century accumulating people, institutions, communities and migration networks. Its foreign-born population rose from 9.6 million in 1970 to around 50 million by 2024. Foreign-born workers now account for almost one in five people in the US civilian labour force, while Indian students alone number more than 360,000.

Khanna argues that the accumulated advantage is difficult to copy. “What cannot be assembled in a decade is the network,” he said. “That is a century of compound interest, and nobody can buy it.”

None of this means the American Dream worked as advertised for everyone. Migrants faced low wages, discrimination, high housing costs, uncertain legal status and long waits for permanent residence.

America’s achievement was not convincing the world that everyone who arrived would become rich. It was convincing generations of people that getting there gave them permission to try.

And once enough people had taken that chance, America no longer had to sell the dream alone.

Its immigrants began selling the possibility to the next generation.
