Bunker Hill Community College is canceling its summer study abroad programs in response to Trump administration immigration policies, WBUR reported.

“Our first priority in any Study Abroad experience is the safety of our students and staff,” read a statement from the community college to WBUR. “With the changes in national immigration policy and enforcement that have emerged over the last several weeks, including the prospect of renewed travel restrictions, the College will redirect this year’s exploration and learning to U.S.-based sites.”

The community college planned to send about 60 students to Costa Rica, Ghana, Japan, Kenya and Panama for two-week educational programs between May and July. The decision to cancel the trips came after news reports that the Trump administration is considering a travel ban on dozens of countries.

Biology professor Scott Benjamin, who’s led the Costa Rica trip since 2002, told WBUR that college leaders were concerned for international students who planned to go on these trips. International students make up 7 percent of the college’s student body.

“The school was just very worried about the probably remote, but still potential possibility that we could go away and come back, and a student couldn’t come back into the country,” Benjamin told the news outlet.
