I support the efforts of the city to combat the influx of illegal aliens, but the burden should be on the government, not private citizens.
If the private citizen is the one profiting from the business transaction, why shouldn't the private citizen be responsible for making sure the transaction is legal?
It's not any more difficult than doing the rest of the due dilligence in renting to someone - you are just adding in another step.
I just sent you a freep mail regarding this.
