There isn't really such a thing as an immigrant visa. These non-immigrant visas are the only legal route to come here, by and large, excluding a few obvious exceptions like marriage to an American.
Also, it's quite hard to become a permanent resident/immigrant even without the obstacle of this being categorically prohibited. My family, for instance, overcame some very low odds of success to make this happen (highly educated, both PhDs, for what it's worth).
I have learned that most Americans, probably through no fault of their own, have absolutely no understanding of how their own immigration system works. The options for legal immigration were _extremely_ limited and byzantine, and have been for decades, long before Trump.
