He's not letting you in.
Actually, the kind of foreign person who would support Trump's America, or at least the picture he paints of it, may well be welcomed with open arms.
As a system analyst and strategist, I consider the U.S.'s best hope would be to create an environment which people would wish to live in, then selectively accept the most 'cream of the crop' from other nations. This means liberty, fairness, opportunity, and rule of law.
My only qualm about this strategy are ethical; it screws other nations and puts them at a perpetual disadvantage. My hope would be that in order for the other nations to compete they would try to better their own country as well. I admit that this hope is fairly pie-in-the-sky though. If we really wanted to be good guys, we'd refuse to take good people from shitty countries with the hope that they would stay home and work on fixing their problems.
I only state this that I am about to state because Americans are ignorant of bottom-line law. I am kinda in favor of not having our nation overrun by a bunch of people from elsewhere. But, here it is.
Any foreigner who slips into America, and is caught by the authorities can do this. When he gets his day in court before they send him out of the country, he can file a common law claim as a man, against the man or woman who is not allowing him free travel in America. If he knows English well enough to do this, the jury just might award him freedom to remain.
To a degree my views are shaped by working in environments where probably half of my peers were H1B. They did a huge amount for the industry and the country (to the extent that our work was not net negative and history is yet to be written on that one...one way all of us working on our tasks were at least neutral.)
Actually, my experiences in school and simply just personal philosophy and study of history led me to my way of thinking before I worked in the tech industry. My experiences there simply solidified up my views.
To me 'American' is a mindset, and the best proxy for it is outlined in our constitution. Even now, 240-ish years and much gorp/gov abuse later, that still holds. That is why I say that there are a lot highly 'American' people have never been to our country and may not have even considered it. Unlike the above (scrape other nations for talent), this construct is a fairly recent invention of mine.
I've never been much of a patriot of flag waver and only fairly recently started to appreciate certain of the positives of the country as I study things more. Now I am quite interested to retain hold on what we have left and hopefully claw back some of what we've lost. Immigration could help a bunch or hurt a bunch depending on who is implementing it. It could be the case that so many native born Americans are so brainwashed and fucked up that immigrants are actually our only hope.
