Columbia University Provost John Coatsworth said in a statement today:

First, you should know that the University will neither allow immigration officials on our campuses without a warrant, nor share information on the immigration status of students with those officials unless required by subpoena or court order, or authorized by a student.  Moreover, New York City continues to be a sanctuary city, with special protections for undocumented immigrants, and Mayor de Blasio recently affirmed that local law enforcement officials will continue to operate consistent with that commitment.

If the Deferred Action for Childhood Arrivals (DACA) policy is terminated or substantially curtailed and students with DACA status lose the right to work, the University pledges to expand the financial aid and other support we make available to undocumented students, regardless of their immigration status.  It is of the utmost importance that federal policies and laws do not derail the education of students whose enrollment at Columbia and other colleges or universities is made possible by DACA.  We subscribe to the view of the Association of American Universities that “DACA should be upheld, continued and expanded,” and we will continue to express that commitment in the future.

To provide additional support, the Office of University Life is hosting a series of small-group, private information sessions specifically for undocumented students in our community, including DACA recipients, to provide support and guidance regarding possible changes in the law.  Affected students can contact the Office directly for more information.  Separately, our International Students and Scholars Office (ISSO) is also scheduling information sessions and prepared to provide assistance via its telephone helplines to any of our international students with questions or concerns.  For more information about resources, support and reporting options regarding discrimination and harassment, please see http://universitylife.columbia.edu/news/2016/11/resources-students-and-other-columbia-community-members.

The commitments outlined above emerge from values that define what we stand for and who we are as a University community.  Indeed, Columbia College and the School of Engineering and Applied Science have amplified their commitment to undocumented undergraduate students pursuing their first degrees by continuing to meet their full financial aid needs as has long been our policy and also by treating applications of undocumented students no differently than those of students who are U.S. citizens or permanent residents.  The experience of undocumented students at the College and Columbia Engineering, from the time they first seek admission through their graduation, will not be burdened in any way by their undocumented status.

Trump can see Columbia from his house.
