The Middle East campuses of American universities are expecting — or perhaps just hoping — to be open for classes as usual for the coming semester, even as the United States’ conflict with Iran poses new risks in the region.

Some American schools have long run programs in Qatar and the United Arab Emirates. The war, however, meant that students spent much of the spring semester enduring shutdowns, evacuations, online courses and other emergency measures. But the unraveling of the cease-fire between Washington and Tehran is not yet curbing universities’ ambitions to teach as they ordinarily would in the Middle East.

The University of New Haven is still planning to inaugurate its new campus in Riyadh, Saudi Arabia, though probably without some faculty members it intended to send from the United States.

“The word in Saudi is that students are going to school and it’s business as usual,” Jens Frederiksen, New Haven’s president, said in an interview. “We’re proceeding with the launch.”

For American universities, campuses in wealthy Persian Gulf states can offer new revenue and welcome clout. Those perks, though, come with sporadic political headaches at home, reputational perils and regional safety concerns. After a strike on a physics building at a university in Tehran, Iran’s Islamic Revolutionary Guards Corps warned in March that “American universities in the West Asia region are legitimate targets for us.”

By then, American schools had begun closing campuses and turning to remote classes. But the relative lull of recent months left many administrators encouraged and publicly optimistic that the campuses would be able to run normally as students return for another semester.

Virginia Commonwealth University, which has a presence in Qatar, said it was “planning to begin the fall semester with in-person instruction and campus operations as scheduled.” But the school said it was “prepared to transition temporarily to remote instruction and operations should circumstances warrant.”

Spokesmen for Carnegie Mellon University and Northwestern University described similar approaches for their Qatar campuses.

Cornell University, whose medical school has a presence in the country, said the campus would “continue to follow guidance from the Qatar Ministry of Interior, monitor developments and provide timely updates.”

Meghan Dubyak, a spokeswoman for Georgetown University, said she did not “have any updates to share at this time” about plans for the university’s Qatari operation, which has been describing the campus as “open with limited services.”

Texas A&M, which also teaches in Qatar, did not comment on its plans for the weeks ahead.

In the Emirates, New York University’s Abu Dhabi campus is “planning for in person,” said Wiley Norvell, a school spokesman.

The U.S. government warned this week that the security situation could shift unpredictably.

“Iran and groups supportive of Iran may target other U.S. interests overseas or at locations associated with the United States and Americans throughout the world, including U.S. businesses and other institutions,” the State Department wrote in an alert that said Americans “should reconsider travel to and through” the Middle East.

Americans already in the region, the State Department said, “should exercise caution and heightened vigilance.”

As New Haven prepares to open its branch in Riyadh, Dr. Frederiksen, the university president, acknowledged that the student body might be different than once envisioned. He said he expected most of the debut cohort’s students to be from Saudi Arabia and that the campus would probably be “light,” for the time being, on pupils from elsewhere.

He said that he and other university officials were in close contact with the Saudi authorities so they can better discern whether to invoke contingency plans for the campus.

“We’re incredibly, acutely aware of how dynamic situations are and what are sort of responsible for trigger points to say, ‘OK, then let’s go hybrid for a while,’” Dr. Frederiksen said.

But Dr. Frederiksen cautioned against relying on the decisions of other campuses across the region.

“You can draw lessons and pay attention, but, obviously, Riyadh or Saudi is not Bahrain or another one of the Gulf states, so I think there are some nuances there,” he said.
