I’d be okay with
First offense - 30 days in jail, then deportation
Second offense - 5 years in prison, then deportation
Third offense - 20 years in prison and we bill your country of origin for all costs of your incarceration. If they don’t pay up you get only the minimum sustenance to keep you alive and no medical care. Then deportation to the farthest point of your country of origin.
Any crimes committed on U.S. soil while being an illegal alien are automatically elevated to being a felony with a mandatory minimum of one year. Yes, that applies to littering and jaywalking, too.
I have NO desire to support these people in our prison system.
