Listen, I know how you feel. My parents aren't doing too bad, but they are far from even being considered low middle class. They had me at a young age and immigrated here with me in mind. I'm 20 about to be 21 and they are paying for my college, and barely making it for themselves and my younger siblings. I have considered doing the same thing, but the one thing I realize is that no matter if I get a great job back in my home country I will still not be making enough to support myself and send money back here. Instead I got a job and applied for as many scholarships as I could. I'm slowly but surely relying less on them and getting myself up on my feet. It wasn't easy, but its not impossible. They still help me out but I manage to carry some of the burden on my shoulders. Don't lose hope, especially now. Things look difficult and hopeless now but things always get better. It's impossible and expansive for the government to search, find, process, and deport millions of people. They're tough on us now but as soon as the border is secure they will pass some form of a bill that provide a way for us ALL. Just hang in there and don't lose hope. Keep in mind how much you will be able to help your family when you become a resident and work within your career choice.
