To discourage illegal immigrants: Publicize the negative points about being an illegal in the U.S. First: As an illegal, you are virtually invisible - no papers = you are a non-person = can only get a job off the books = lower paying job forever. Second: If you thought the cartels were bad in your country of origin, when they get a hold of you and/or your children here, you will be easily intimidated to do as they wish = you will live in fear of being found by the U.S. government and you will live in fear of a gang getting a hold of you and/or a member of your family for nefarious acts. You and your family will always be vulnerable to others who might virtually enslave you. Third: I also think that children born of illegals (either mother or father or both) should not qualify for automatic citizenship. There are probably other reasons, and I welcome additional ideas.
