The Passport of Knowledge

This week, changes to student visa rules in the United States once again placed international education in the headlines.

Visa policies evolve. Governments change. Political priorities shift. The larger story endures.

Around the world, universities have quietly become one of the most enduring sources of national influence. Not simply because they educate students, but because they shape relationships, ideas and trust that often outlast governments themselves.

Long before Harvard professor Joseph Nye introduced the concept of soft power, universities were already among its most powerful expressions.

Nearly a thousand years ago, scholars crossed Europe to study in Bologna. Oxford and Cambridge educated generations of political leaders from every continent. Paris became synonymous with philosophy, Berlin with scientific discovery, and later, institutions such as MIT, Stanford and Harvard helped define the modern innovation economy.

Students rarely leave university carrying only a degree.

They leave with languages, friendships, professional networks and a deeper understanding of another society. Those connections often outlive political alliances and trade agreements.

The influence of education has often travelled further than politics.

History offers compelling examples. Her Majesty Queen Rania Al Abdullah of Jordan graduated from the American University in Cairo before becoming one of the world's leading advocates for education. Former United Nations Secretary-General Kofi Annan studied in the United States before serving as United Nations Secretary-General. Across generations, ministers, diplomats, entrepreneurs and scientists have first built international friendships not in cabinet rooms, but in lecture halls, university cafés and student residences. Those relationships continue to influence business, diplomacy and international cooperation long after graduation.

Today, the scale of that exchange is unprecedented.

According to UNESCO, more than 7.3 million students now pursue higher education outside their home country, compared with around 2 million at the turn of the century. What was once an opportunity for relatively few has become one of the defining characteristics of the global knowledge economy.

That growth is not accidental.

For decades, countries such as the United States, the United Kingdom and Australia recognised that welcoming international students strengthened far more than their universities. International students contributed an estimated US$44 billion to the U.S. economy during the 2023–24 academic year, while Australia's international education sector generated more than A$50 billion in 2023–24. Yet their most enduring contribution cannot be measured in financial terms.

The relationships forged during those years often last a lifetime.

Today, a growing number of countries are making international education a strategic priority.

Across the Gulf, governments have invested heavily in world-class universities, research ecosystems and international partnerships. Singapore has spent decades positioning itself as a regional education hub. European universities continue to expand programmes taught in English to attract students from around the world.

Today, many countries see international education as part of a broader national strategy.

Increasingly, it is about creating places where talented people choose to learn, collaborate, innovate and, in many cases, remain.

The timing is no coincidence.

Many advanced economies are experiencing ageing populations and declining numbers of domestic university-aged students. At the same time, innovation has become one of the principal drivers of economic growth. Increasingly, the question is not only who can produce knowledge, but who can attract the people who will create the next generation of it.

We often speak about universities as institutions of learning. They are.

But they are also where tomorrow's diplomats meet tomorrow's entrepreneurs. Where future ministers debate future scientists. Where researchers meet lifelong collaborators.

The most enduring alliances between nations are often formed long before people enter government.

They begin in lecture halls, university cafés and student residences.

Governments determine the rules of movement. Universities shape the exchange of ideas.

Both matter. History suggests the latter often leaves the longest legacy.
