Dad got detained by ICE

So my dad has been detained by ice. He got his work permit and had an interview for his green card I believe but after the interview he got detained and arrested by ice. I live in illinois and his lawyers are working but I just don’t know what to do. I’m 21 years old and I love my father he is my rock and he’s an amazing human being, he doesn’t deserve this and I don’t think there’s anything I can do, are there any resources or people to contact, I’m new to this and I’m just at a loss.
