But as a nation of laws we base out society on following the laws and trying to change the ones we disagree with as things evolve. Since I get some firsthand experience with the visa laws and regulations from my job I know that things tighten and loosen, sometimes without much warning, all the time. Change can happen, does happen, and will happen, but while we discuss this from the sense of the moral rightness of the arguments the other side feels the same way. Sadly we are a nation that is sharply divided on this instead of meeting in a commonsense middle. What's the saying? Imagine someone of average intelligence and then realize that half the country is dumber than that?
