I am suggesting a “Pay to Stay” policy for illegal immigrants currently in the United States.

Once they are employed they would have a set tax rate, with no opportunity for tax refunds or write offs for the first generation. Tax rate could be determined multiple ways by people with much more information than I have. I would consider the financial burden on the health system, school system, and many other factors.
I’m seeing a lot of other immigration ideas that could directly be tied in
