How can I find out who reported someone to immigration for deportation?
You can’t. Laws prevent it. There may not even be any record of it anywhere. If there is a record of it, it would be in one physical location, and, not accessible to people that don’t need to know. WOrkers would have no reason to know- so, they wouldn’t be able to access it. Social workers used to be put in danger when they would have information such as this. As such, it is unaccessible to everyone. There is no need to know, anyone. IF the person was here illegally, they were breaking the law, and, who reported it is moot.
