I put that in quotes because as of now, no one is quite sure what that means. There seems to be some consensus between a small group of colleges and LACs that it means, basically, not volunteering to locate, transfer or otherwise attach private information about their students, including undocumented immigrants, without a warrant or a subpoena. The schools so far include:
Portland State University
Reed
Wesleyan
Pitzer
Connecticut College
The University of Pennsylvania
Swarthmore
There is some question as to whether the California State University System (CSU) should also be on the list. If so, that would multiply the number, I believe, by several fold.
Here’s an article from The Daily Pennsylvanian, one of the oldest student newspapers in the country:

Here is a similar announcement in the Wesleyan student newspaper: http://wesleyanargus.com/2016/11/20/roth-declares-sanctuary-campus/
FWIW, there have been a wave of announcements from similarly prestigious colleges and universities across the country that have espoused similar sentiments and intentions to protect student privacy - to the extent permitted by law - but, that have not adopted the use of the word, “sanctuary”.
Adding Oberlin to the list:
Portland State University
Reed
Wesleyan
Pitzer
Connecticut College
The University of Pennsylvania
Swarthmore
Oberlin

Wesleyan doubles down on its policy on the treatment of undocumented students:

Is there an updated list of colleges that are sanctuary campuses/openly against Trump’s immigration policies?
It depends on how you define “openly”. In the immediate aftermath of the November election hundreds of colleges issued statements in support of President Obama’s DACA executive order which allowed children of undocumented families to continue their studies and to qualify for work-study grants while doing so. Since then, a lot of the conversation seems to have shifted to academic discussions about the meaning of the word, “sanctuary”. Some of the most awkward have taken place on campuses with the most to lose (potentially) in federal funding in case the current situation deteriorates even further; among them were Category I research universities (as defined by the Carnegie Foundation) such as Harvard, Yale, Princeton, NYU and Chicago.
Personally, I would add Columbia and the 23 campuses of the California State University system to the list:
Portland State University
The California State University System (CSU)
Reed
Wesleyan
Pitzer
Connecticut College
Columbia University
The University of Pennsylvania
Swarthmore
Oberlin
