Immigration authorities will not come knocking and kicking your relatives door and drag you out of that place.
Your relatives are in no legal responsibility of your actions (unless you are running a criminal activity and they are complicit in that).
Otherwise, you can think of them as a landlord.
Why would the landlord be in problems due to the tenant immigration mess.
So, don’t worry about your relatives and try to fix your current situation. If your relatives want to kick you out due to distrust or whatever… that’s a different story.
