I agree with you. If I had my way, I might actually make it easier to legally immigrate, but I would enforce those regulations by securing the border. It doesn't matter how tough you are on paper if you are not willing or able to back it up. Even if we did have an "open border", as far as everyone is able to immigrate legally, we would still need to have a secure border, so that we can ensure criminals, terrorists, spies, etc are regulated, and so that we can actually document who is coming and going.
I wouldn't make it easier for people to come here and become citizens, but I would make it easier for immigrants to come here and work and feed their families. I would just create a guest worker program where people could come here and work right away without having to wait in line to become a citizen. But, I don't think we should make it easier to become a U.S citizen when that will simply allow the Democrats to wipe out the Republican Party across the entire United States.
