These illegal immigrants do not have to arrested. They do not have to be deported. They all know that they are here illegally so just LEAVE.  Go home.  Save everybody (mostly yourselves) a ton of hassle and simply go back to where you belong,,,,,your home.  The U.S. does not have to hire thousands of more immigration officers if personal responsibility is taken and these illegal immigrants simply go back to their countries of origin.  It's this defection of common sense that caused the 2016 election to swing the way it did.
