Note: I'm Canadian but live close to the border and cross occasionally.
I would personally never "work" in the US without the right visa, because I am well-aware of the laws and am a very knowledgable man. I'm also reasonable, and the US government is not reasonable sometimes. I see that changing under Donald Trump, because I firmly believe that he will change his mind and end up being socially liberal because of people like Peter Thiel. I'm just doing a public service for this innocent man.
Downvote the fuck out of me, do I care? Of course not. I will always stick up for the little guy even when it's unpopular.
Please identify any one such law. Bonus points for describing how a President implements laws on his own.
Also, US Presidents on both sides of the political spectrum have issued "Executive Orders" to bypass both Congress and the Senate and write things into law. They are considered unconstitutional by some, and constitutional by others.
I'm not sure what I find more absurd about your comment: it's either the fact that you think of yourself as some sort of self-appointed immigrant savior, or the cognitive dissonance you display when it comes to your political beliefs.
