Immigration has been a problem for fifty years and no elected officials have given much more than lip service while campaigning except DT. The wait in Mexico while your paperwork is done was a good start. However, there needs to be a clear "path to citizenship" that is reachable by being able to support yourself, good conduct, and acclimating to the culture.
Knowing who is coming into the states and for what reason is important. Are they here learning to fly planes to hijack several and fly them into buildings, like at 9/11? America has needed workers, the construction trades have been dominated by Hispanic labor for years. Forty years ago, Hispanics were doing labor work, then they started learning the skills of form carpentry, finishing concrete, masonry laying brick etc, and ironworkers just to give you scope. Now, they are reading plans off of tablets to layout jobs and have smartphones. And they are workers, I'll say that. The Union Trades had the market on construction and their demise corresponds to immigrants. Now Kevin O'Leary and Mike Rowe have YouTube programs encouraging young ones to take a second look at the trades. Why go to college for a low-paying job and have $40k in student debt?
I had some contractor friends inform me after they had been drinking for several hours, that they had work visa applications for over 150 workers a year. (One of their partners was from Mexico and he would drive down to the smaller towns and recruit young men to work.) I asked, "How can you justify asking for 150 workers?". They replied they couldn't find workers. I replied, there are workers everywhere, what are you talking about? They said, "Not for what we are willing to pay".
I was talking to some young men staying at the hotel and working in construction. I told him they needed to join the trade unions and gave him an idea of the pay differential and other benefits. He looked at me in disbelief.
Democrats are not interested in solving immigration as is clear with the sweep of a pen that has made immigration a free-for-all clown joke and the current crisis at the border is really inhumane. China and the rest of the world are laughing at the stupidity of American leadership. Look what has happened in Europe i.e France with open borders). The situation with Chinese students and immigrants can be questionable also, many are just informers (spies) for the CCP.
