Bypassing Immigration Law Enforcement By Using Civil Action

What if the employers of illegals were held to be their sponsors and were found to be responsible for all financial liabilities incurred by hospitals, schools and government entities for services to those employees and their dependents?

The enforcement would be by civil suit and I imagine an attorney or two could be found who would press cases on contingency.

Wouldn’t cost taxpayers a dime and would be the mother of all deterrents!
