It should only take you about a minute to read what I wrote above but whatever. Your new question would take much longer to answer thoroughly but I'll help get you started.

The Immigration and Nationality Act of 1965, also known as the Hart–Celler Act and more recently as the 1965 Immigration Act, was a federal law passed by the 89th United States Congress and signed into law by President Lyndon B. Johnson.^[1] The law abolished the National Origins Formula, which had been the basis of U.S. immigration policy since the 1920s.^[2] The act formally removed de facto discrimination against Southern and Eastern Europeans as well as Asians, in addition to other non-Western and Northern European ethnicities from the immigration policy of the United States.

Emanuel Celler was born on May 6, 1888, in Brooklyn, New York. His parents, Josephine (née Müller) and Henry H. Celler, were each the children of German immigrants. His paternal grandparents and maternal grandmother were Jewish.

Before that jew wrote that bill and got it passed the USA mostly just let in Northern Europeans, aka the best people for a modern society. It's all been downhill for American genetics since the 1965 immigration act.

The United States Department of Homeland Security (DHS) is the U.S. federal executive department responsible for public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management.

That's run by Alejandro Mayorkas. His father, Charles R. "Nicky" Mayorkas, was born in Cuba. He was a Cuban Jew of Sephardi (from the former Ottoman Empire, present-day Turkey and Greece) and Ashkenazi (from Poland) background.

I'm not sure if you've noticed but the demographics of the USA are getting dark pretty fast. The jews made it legal to bring in a bunch of them 60 years ago and in the past decade or two they have been bringing them in illegally, by the tens of millions.

That's just scratching the surface but there is much much more. Follow the money of the NGOs that are helping settle Haitians in Ohio and niggers all over the place. They are trying to do the same in Japan and Asia in general, but the Asians aren't bending, at least not yet. They don't let a lot of Africans or Arabs into Israel though. Strange since in the jews in the USA like Chuck Schumer, the senate majority leader, are such big proponents of ethnic diversity and giving citizenship to illegal immigrants here, but not in his home country.

I've explained my line of reasoning about genetic differences in an earlier post. I said that blackies run and jump faster and higher than whites on average because they spent the last 100,000 years or so chasing their dinners through the planes and jungles of Africa. You are the one trying to reason that it is something about the way blacks raise their children that makes them really bad at math but really good at running and jumping. Can you please explain what you think it is about black parenting that leads to these results?

I've looked into the downfall of Detroit and Kansas City and New Orleans, Flint, Jackson Mississippi, and countless others. The story is always the same, too many niggers. You think poverty and violence comes out of nowhere, it follows the niggers around wherever they go. They are the cause of the poverty and violence, hence why I don't want them around. Prosperous cities don't just become poor out of nowhere, they don't become prosperous out of nowhere either. White people build great cities out of nothing and then blacks destroy them. Look at the nigs in England, Sweden, Ireland, France, Germany. They are overall poor and violent in every country that will let them in. It happens every time everywhere on Earth. Find me one place in the world where an area went from majority white to majority black and got better. It doesn't exist. The nigs fuck it up every single time.

Check out South African crime data before and after Apartheid, and make sure you check the demographics of the criminals. South Africa was the greatest nation in Africa when it was controlled by whites, now it is controlled by blacks and is deteriorating rapidly. Also look into Orania, an all white South African town that is a really wonderful place, and improving everyday. 

Israeli jews have a comparable standard of living to that of the people in the USA. It is much higher than that of the average African country. The USA has given Israel so much money it works out to something like half a million dollars per Israeli jew. They are living just fine. They shouldn't be, but they are thanks to whites. I'm sure the Arabs still left in Israel have it rough since the jews are evil bastards but Arabs have it rough everywhere. 

You seem to be interested in scientific truth, which is great, good for you, but a lot of modern "science" is retarded. I remember when science said that men had XY chromosomes and women had XX. Now "science" says that doesn't matter and chicks have dicks. Chopping off a kids dick and then cutting out some of his colon to attach to the hole left in his body that has to be stretched open daily to prevent the wound from healing and calling that a vagina used to be criminal child mutilation, now it's healthcare and good parenting. You've obviously had the firmware update but I'll stick with my tried and true white guy science.

Don't trust the Government or their agencies either. It used to be when you found a laptop worth a bunch of pictures, videos, and emails from a guy and he's smoking crack, fucking prostitutes, and talking about colluding with foreign governments in return for large bribes, that was a crime and that person would be arrested and the laptop would be used as evidence in his trial. Now the intelligence agencies, president, and the media all just call it "Russian disinformation" for a few years, then admit it was in fact a real laptop and just tell everyone to forget about it, and a lot of people do forget.

Don't be a sheep. Think about what you believe, and if you truly believe something then live it. I moved out of a shitty mixed race area into a very white one and it was a great decision for me and my family.
