How long does it take for American immigrants from successful appeal to notification of visas?

Maybe I'm just ignorant, but both investment immigrants and political immigrants should get green cards, that is, residence permits in the United States. It may take six months to two years for a temporary green card to become a permanent green card, but as long as you have a green card, you don't need a visa to enter and leave the United States, let alone a citizen.
