As early as our colonial times, arriving religious sects were often spurned, even by those who worshipped the same God but in a different church. Immigrants from the Old World were often ostracized by countrymen whose families had arrived generations earlier. Federal legislation periodically imposed quotas, responding to fears that newcomers would take jobs at any price and displace American workers in the factories and farms.

Our immigration debates have rarely been simple. Yet time and again, after periods of angst over who should be allowed to enter, the nation has consistently found a path forward. This is how a uniquely American “melting pot” took shape—not by accident, but through debate, evolving standards, and shared civic commitment. Over 250 years, that process has strengthened the fabric of our democracy, defined our nation, and led to economic growth, innovation, and global leadership. We will likely continue to debate immigration policy far into the future, but looking to our past helps illuminate how best to proceed.

For the tens of millions who sought entry and opportunity here in the New World, that historic debate played out at the very gateway to America. Castle Garden, at the foot of Manhattan, first received those arriving in New York Harbor—including Nikola Tesla and Harry Houdini—alongside countless others who would build our cities, harvest the farms, and power our nation’s emerging industrial revolution.

Soon, a purpose-built federal facility would replace Castle Garden on a spit of land in New York Harbor that would become known worldwide as Ellis Island—where America would evaluate the hopeful against qualifications for entry. Immigrants would face a review process that required everything from medical exams to skills assessments to prevent them from becoming a burden on society. A fraction would be deported; for those turned away, the experience could be devastating, but Ellis Island sought to balance order with compassion.

Immigrants could also be excluded from entry for political beliefs that advanced anarchism and later communism, barred for health issues or past criminal conduct. The system was imperfect, but it was structured, reflecting a nation attempting to balance openness with law and order.

Through successive waves of controversy, that balance has endured. Today, as immigration once again stirs deeply held views across our society, it is worth remembering that such moments are neither unprecedented nor permanent. They are chapters in a longer story that has consistently tested both our instincts and our institutions. As the records of Ellis Island attest, we are, and have always been, a nation of immigrants.

The men and women who passed through Ellis Island could not have imagined the industries their successors would create. But the impulse that drove them—to build something new in a country defined by possibility—runs unbroken to the present day. The United States will remain the destination for the world’s brightest minds, as well it should be. Consider who has strengthened our nation’s role as an incubator for innovation in just the past decade:

· Sundar Pichai, born in Chennai, India, has led Google through its most ambitious advances in artificial intelligence and cloud computing—helping make the company the defining platform of the information age.

· Satya Nadella, also from India, essentially reinvented Microsoft, repositioning it around AI integration and cloud services and restoring it to its place among the world’s most valuable companies.

· Elon Musk, born in South Africa, co-founded SpaceX and became an early investor and driving force behind Tesla, fundamentally reshaping commercial space travel and the global electric vehicle market.

· Katalin Karikó, a Hungarian-born biochemist, spent decades pursuing mRNA research at American universities before her work became the scientific foundation for the COVID-19 vaccines that reached billions of people worldwide.

These innovators are far from alone. In the decades to come, we can expect immigrant engineers and researchers to drive breakthroughs in semiconductors, biotechnology, and energy. A 2022 study by the National Foundation for American Policy found that immigrants founded or co-founded more than half of America’s billion-dollar startup companies.

All of these innovators never set foot inside Ellis Island, but their shadows are there within The Great Hall. A future generation of innovators will follow them—seeking a land of opportunity that welcomes those whose ideas can literally create the future.

For nearly two and a half centuries, Ellis Island has remained an enduring symbol of an America determined to welcome legal immigrants on our nation’s terms—recognizing the immense talent and energy they bring while seeking to hold true to its mission of compassion, order, and upholding the law of the land. As we prepare to celebrate a defining American anniversary, the lessons of that history are clear: America is strongest when its doors are open to those who come lawfully, contribute fully, and commit to the ideals that have always defined this nation. Policymakers today would do well to build an immigration system worthy of that legacy—one that is orderly enough to command public trust and open enough to attract the talent our next 250 years will demand.
