I fully understand. Australia is another option if not Canada. For me, I don't like to live on the edge, every decision I made in the US was dependent on my visa. Why should I risk and depend on my luck for US immigration's mercy when I have the skills ? I did not know the pitfalls of US broken immigration system when I came to the US. If I knew earlier, I would have immigrated somewhere else. Anyways all I can say is 4 years of my life was wasted by staying in the US.
