Apparently, if you have a few billions to invest in Trump or to buy weapons.
Or even a few millions.
Seriously though, there may be an investment visa, I am not sure, all the info is online, look it up. Developed countries usually have all their info accessible online for everyone to look up, unlike how it is in Lebanon.
However if there is a US investment visa it is very difficult to obtain. Definitely not guaranteed.
Gah. Since I have no life, I looked it up for you:

There are other countries where you can be legible for residency and immigration by making a "small" investment such as buying a house. Maybe Lithuania, or Cyprus, I am not sure. There are also countries with exotic immigration laws, such as "Svalbard" where everyone is welcome to immigrate, you don't even need a visa, as long you show that you can survive in the arctic conditions there.
Oh, by the way I found the link to this article I read:
