The horrifying actions of ICE, kidnapping immigrants & international students & holding them without charges or trial, have now come home to UNC. aculty Chair Beth Moracco told us yesterday at least 6 UNC students had visas revoked. It's time to act for all of us, or know we remained silent 1/2
Dear Colleagues:
I have been out of town attending a conference and was dismayed to learn from news reports that the visas of six of our international students have been terminated by the federal government. At this time, I do not have information about why these students were targeted, though similar actions are occurring at universities across the country, including Duke and NC State.
Since last night, I have heard from many faculty members who are distressed and angry, not only because this has happened, but also because we had to learn about it from media reports. At this point, we have not received any communication from university administration. I have written to Chancellor Roberts and Vice Provost for Global Affairs Barbara Stephenson to request as much information as possible, and that it be provided to us promptly.
However, information is not our only need. As a faculty, we also urgently need to speak up in support of our international students and colleagues, who are an integral part of our vibrant academic environment at UNC. They enrich our classrooms, our research, and campus community life with their perspectives, ideas, and experiences.
We also must speak up for our values as an academic community, especially academic freedom and free expression, the cornerstones of a thriving institution of higher education.These values ensure that universities remain spaces where ideas can be explored, debated, and tested. They empower both faculty and students to engage with complex and evolving issues, fostering the environment of intellectual growth and critical thinking that we all cherish. While I do not know why our students' visas were revoked, I know that students at other campuses appear to have been targeted for their speech. UNC has a long history of students and other campus community members expressing their views, and the peaceful expression of viewpoints should never be a ground for removing a person from our community. Indeed, freedom of speech and assembly are enshrined in our country’s Constitution.
I will share any information I receive from the administration with you. In the upcoming days, as we learn more, members of faculty governance will be considering potential actions we can take to support these six students as well the hundreds of international students, scholars, staff, and faculty here at UNC who may be affected by these and similar actions taken by the federal government. We will likely be reaching out to many of you for your perspectives and guidance. In addition, the April 25 Faculty Council meeting is a joint meeting with the General Faculty during which we can further discuss and propose action.
Thank you for the deep concern and care for our students that I see reflected in your anguished emails, texts and calls. In these terrible times, such collective compassion is uplifting—and essential.
In solidarity,
Beth

I think some people hear “grants” and think that without them, scientists and government workers just have less stuff to play with at work. But grants fund salaries for students, academics, researchers, and people who work in all areas of public service. “Pausing” grants means people don’t eat.
