In light of President Donald Trump's executive order suspending non-immigrant and immigrant visas, University of Arizona President Ann Weaver Hart urged the school's international students and scholars to postpone any international travel plans.
In an email sent to all students and staff, Hart expressed "serious concerns" about the executive order, which bars entry to citizens of seven countries that are mostly Muslim. It also suspends the refugee program.
The executive order sparked protests at several airports nationwide.
Hart said in the email that the university has received reports of students and scholars at other universities who were airborne when the order was being signed and were detained upon arrival.
She said she also heard from UA students who are fearful of traveling internationally, despite their visas being legal.
"We are deeply concerned for the well-being and treatment of our foreign students, scholars, researchers and professors," Hart said. "This approach violates the principles on which international university communities of thought, learning and research are based and will jeopardize the very mission and purpose of the university."
It's not clear whether or not any UA students, staff or scholars are at risk of being barred from entering the United States. A UA spokesman could not immediately be reached for comment Monday morning.
