I work in a research group with a large number of international graduate students. Recent news in my country (the United States) has been deeply unsettling for some of these students, especially the ones who hail from "unwelcome" countries (see here).
As a U.S. citizen, I (personally) feel guilty and embarrassed over the current goings-on (nor do I agree with them), though I certainly do not expect other Americans to necessarily feel that way too. Many of these students in my lab know my personal feelings on the matter. But at the end of the day, there isn't much I can do right now to affect national policy, so I'm trying to think more locally.
What, if anything, can I do here in my lab/department/university to help my fellow students/peers/friends?
