Ask HN: Anything we can do for those impacted by the US immigration ban?

Just posted this on my FB wall, figured someone around here might have ideas.

r.e. recent immigration policy changes, practically speaking: Anybody here, or know someone, who's stuck in an airport/country they expected to leave today, and needs a sandwich/a ride/a place to stay/a friendly ear? Seems like we're going to need a network of care to look after the stranded.
