ICE would not be relevant if the issue wasn't coming from a group of people trying to immigrate in an illegal way. Just to make it clear, ICE works against illegal immigration, and that's why nobody would consider calling ICE for situations that does nothing to do with illegal immigration. Also I am not sure if you actually read anything I wrote other than a word "ICE", but I thought I made it clear that it isn't the direction I want to direct this issue towards. Their immigration status was only brought into the conversation, because we recently learned that the issue that had been tormenting our lives for months started from their unlawful immigration status. To be specific, their "immigration status" is none of my business, but the fact that group of people who should not be living upstairs from mine according to their lease contract staying there and creating much disturbances in our lives is very much of my business, and it just so happened that the reason they're there is due to their immigration status. Plus, who I live with is completely none of your business.
