I feel that a person's immigration status is really not relevant unless they enter a country to commit criminal acts.Then, I would consider that person as unwanted.Otherwise, let me become a contributing upstanding member of society. Yes, including paying their taxes.
And how do you suppose you do that, being that illegals don't have social security numbers. Do you even understand what an illegal person is?
How about we just say that we want everybody in the country to be legal, so that we know who they are, and they can conform with the establish rules of society.
