re: resources to help with immigration ban, CALL YOUR STATE LEGISLATORS
no, not just your representatives in the national Congress, but your actual state-level legislators. (my national reps are all GOP and all worse than useless, for example)
one of my colleagues is Iranian & her family lives abroad & they need help so we put her in touch w/ one of our local Democratic senators. They’re organizing w/local attorneys and other resources, and they’re trying to help. Don’t restrict yourself to whoever represents your district, either – hassle ALL the Democrats, especially if you know anything about their record / their slate of experience. Even if they’re the minority in the legislature, they can still help put you in touch with people & organizations in your area.
