What is the difference between the payroll tax with a green card and the payroll tax without a green card in the United States?

The biggest difference is that those who don't have a green card don't have to pay taxes, and those who have a green card must pay taxes. Of course, people with green cards also have cash workers (that is, black workers), but according to American national regulations, they have to pay 10%-35% personal income tax to the state. Those who don't have a green card can only work as cash workers (black workers), so they can't pay taxes, and they dare not pay taxes, because both employers and employees are illegal.
