my brother in law was arrested by ice he did go to court but i did not receive any latter from ice tha he had court

When someone is arrested by ICE he/she is typically served with a Notice to Appear. This Notice to Appear may have court date set or not. The immigration court actually sets the date so notice comes from the immigration court. Your brother-in-law can call the immigration court to find out his next hearing date. It is important he not miss an immigration court hearing as he can be ordered removed in his absence.
