Oh that is easy. I've emailed them so many times about other things, they probably are surprised I haven't emailed them about that already.
My impressions from the visit:
The faculty seem like they are very engaged/involved with the students and actually care about their success on academic, professional, and personal levels, which is really nice. The student community also gave me the sense that they are very supportive of one another and not just there for the classes, but also to interact. The SIS building itself is very open and has a big atrium on the main level for people to meet and hang out on the main level so it is conducive to that sort of atmosphere. The current students I talked to were also super willing to answer questions about basically everything, from SIS-specific questions to living in DC, and a few gave me their contact info if I had other questions in the future. Overall it was all very welcoming, and it felt genuine- not like they were just fabricating it for that day.
