“I still think the downside is lower than the upside is high,” said Amy Gutmann, president of the University of Pennsylvania. “The risk is that we couldn’t deliver the same quality education that we do here, and that it would mean diluting our faculty strength at home.”

While universities with overseas branches insist that the education equals what is offered in the United States, much of the faculty is hired locally, on a short-term basis. And certainly overseas branches raise fundamental questions:

Will the programs reflect American values and culture, or the host country’s? Will American taxpayers end up footing part of the bill for overseas students? What happens if relations between the United States and the host country deteriorate? And will foreign branches that spread American know-how hurt American competitiveness?

“A lot of these educators are trying to present themselves as benevolent and altruistic, when in reality, their programs are aimed at making money,” said Representative Dana Rohrabacher, a California Republican who has criticized the rush overseas.

David J. Skorton, the president of Cornell, on the other hand, said the global drive benefited the United States. “Higher education is the most important diplomatic asset we have,” he said. “I believe these programs can actually reduce friction between countries and cultures.”

Tempering Expectations

While the Persian Gulf campus of N.Y.U. is on the horizon, George Mason University is up and running  though not at full speed  in Ras al Khaymah, another one of the emirates.

George Mason, a public university in Fairfax, Va., arrived in the gulf in 2005 with a tiny language program intended to help students achieve college-level English skills and meet the university’s admission standards for the degree programs that were beginning the next year.

George Mason expected to have 200 undergraduates in 2006, and grow from there. But it enrolled nowhere near that many, then or now. It had just 57 degree students  3 in biology, 27 in business and 27 in engineering  at the start of this academic year, joined by a few more students and programs this semester.
