When I arrived at Princeton, I looked around me at the Gothic buildings—younger, I later learned, than many of the mosques of Lahore, but made through ingenious stonemasonry to look older—and thought, this is a dream come true. The university inspired in me the feeling that my life was a film in which I was the star and everything was possible. I have access to this beautiful campus, I thought, to professors who are titans in their fields and fellow students who are philosopher-kings in the making.

I was, I must admit, overly generous in my initial assumptions about the standard of the student body. They were almost all intelligent, and many were brilliant, but whereas I was one of only two Pakistanis in my entering class—two from a population of over a hundred and fifty million souls, mind you—the Americans faced much less daunting odds in the selection process. A thousand of your compatriots were enrolled, five hundred times as many, even though your country’s population was only twice that of mine. As a result, the non-Americans among us tended on average to do better than the Americans, and in my case I reached my senior year without having received a single B.

Looking back now, I see the power of that system, pragmatic and effective, like so much else in America. We international students were sourced from around the globe, sifted not only by well-honed standardized tests but by painstakingly customized evaluations until the best and the brightest of us had been identified. I myself had among the top exam results in Pakistan and was besides a soccer player good enough to compete on the varsity team, which I did until I damaged my knee in my sophomore year. Students like me were given visas and scholarships—complete financial aid, mind you—and invited into the ranks of the meritocracy. In return, we were expected to contribute our talents to your society, the society we were joining. And for the most part, we were happy to do so. I certainly was, at least at first.
