Well, I've been looking for myself in order to leave the US actually. Especially in the height of the fear-based pandemonium and the push to take away our liberties. I've changed my mind since then, but I can try to summarize what I have learned.
It seems the basis for legal immigration in many countries is dependent on having an existing job offer from an employer in that country for a specialized field that can't be filled by a native of that country, having familial relations or being the spouse of someone already a citizen or permanent resident of that country, or being an entrepreneur with some proof/plan that your business will be successful. Some countries allow you to immigrate there on a student visa and you may get a permanent residency if you find an employer there upon your graduation from school. There are also the odd countries that will allow you to immigrate there based on your bloodline (Italy and Hungary will make you a citizen if you can show Italian or Hungarian ancestry, for example) or a large donation (Morocco, I believe).
In the US, there are a couple of different visas that allow you stay temporarily; it seems you are wanting to become a legal permanent resident. You would probably have to start out with a temporary visa and go from there. Here is a link from the US website of all the visa categories:
https://travel.state.gov/content/travel/en/us-visas/visa-information-resources/all-visa-categories.htmlYou may look at the H-2A visa (for temporary agricultural workers). Then when you have this you might talk to your employer about sponsoring you (look at the section of the link where it says "Employer Sponsored - Employment" under Immigrant Visas.)
Another option is the Diversity Immigrant Visa, where people are randomly selected from. That information is here:

https://travel.state.gov/content/travel/en/us-visas/business.html I was wrong in thinking that maybe we had an entrepreneurship visa, like Belgium.
If you are serious about immigrating to the US, you should talk to the closest embassy near you. (Same if you decide on another country). Don't rely on non-governmental websites on the internet for advice. Here is a link to find a US Embassy near you:
