Assume and Analyze this Fact Set

In defiance of Federal Law the State of California has self-declared a Sanctuary State. Border crossing from all nationalities including folks from South, Central Americas as well as China, North Korea, and Middle-Eastern countries are crossing into California without visa's. These people fall into two distinct groups, many seek the American standard of living yet, at least half seek criminal and terroristic economic gain. The total numbers exceed 36 million (at least 10% of our population) and 2,000,000 on an average annual basis in recent years. San Diego and Orange counties have filed lawsuits against the state of California requesting relief from California sanctuary mandates. The counties request the right to follow Federal law with regard to illegal crossings and wish to deputize local law enforcement to deport those lacking visas at the border prior to the actual crossing. In the alternative, San Diego and Orange County request the right to charge a $10,000 visa tax for any and all humans of any age, race, nationality or gender crossing into their counties without the proper federal visa documentation.

The peoples of San Diego and Orange county cite the following damages to their local environment, communities, citizens and public systems: Loss of minimum wage/low skill jobs for the youth, part-time workers and elderly, property crime, identity theft , drug crimes, DUI's, assault and battery, sexual assaults and murder increases. Private businesses, particularly in border areas, have closed due to increasing and unabated crime. Public schools and hospitals are too overcrowded and underfunded to handle the non-paying patient increase. Many crossing the borders have the highly contagious Covid virus's or other communicable diseases that will require taxpayers to sacrifice significant tax dollars be expended on non citizens, while taxpaying citizen needs go unmet. Police and Fire departments are understaffed and underfunded to handle the large influx of population. Homeschooling has increased 30% in recent years due to the lack of school security and proper student-teacher ratios. All essential taxpayer services in the area of housing, health care, schooling and safety(police and fire) are being diverted from taxpaying Americans who include the very poor and homeless in order to assist those crossing into the state illegally. Tax revenues are finite but the need for the services grows exponentially every year due to this situation. Over the past 10 years the total costs from losses in wages, property, and lives has been estimated to be over $500B per day in the U.S. with no noticeable net increase to the tax collections derived from the illegal border crossings. While many of folks crossing hold jobs, over half of their income is sent back to their home countries and is not spent benefiting the U.S. economy.

What recourse does the bordering country of Mexico, San Diego and Orange Counties have and under what Jurisdiction and law?
