So many people here are complaining that ICE is arresting US citizens, but you literally admit that they're interfering. And yes, it's illegal to "forcibly assault, resist, oppose, impede, intimidate, or interfere" with a federal officer. See https://www.law.cornell.edu/uscode/text/18/111
You can do up to 1 year in prison for minor offenses, or up to 20 for using weapons and causing injuries.
